Antilogism and the Validity of Categorical Syllogisms

Antilogism is another method to test the validity of categorical syllogisms. This test of validity is a type of indirect proof in which the conclusion of the syllogism to be tested is replaced by its contradictory. The antilogism of a valid syllogism must meet the three requirements, namely:

  1. There must be two universal propositions and one particular proposition, or two equations and one inequation.
  2. The two universal propositions (two equations) must have a common term between them which is once negative and once affirmative.
  3. The other two terms must appear unchanged in the particular proposition (inequation).

Let us consider the example below.

Antilogism and the Validity of Categorical Syllogisms

Antilogism is another method to test the validity of categorical syllogisms. This test of validity is a type of indirect proof in which the conclusion of the syllogism to be tested is replaced by its contradictory. The antilogism of a valid syllogism must meet the three requirements, namely:

  1. There must be two universal propositions and one particular proposition, or two equations and one inequation.
  2. The two universal propositions (two equations) must have a common term between them which is once negative and once affirmative.
  3. The other two terms must appear unchanged in the particular proposition (inequation).

Let us consider the example below.

Example 1:

All men are mortal.
All Filipinos are men.
So, all Filipinos are mortal.

How do we determine the validity of the syllogism above using the antilogism method?

First, let us symbolize the syllogism in the algebraic notation. Let M stand for men and F for Filipinos. The algebraic notation of the above syllogism is as follows:

antilogism

Next, let us construct its antilogism by replacing the conclusion with its contradictory. The contradictory of a proposition in algebraic form is easily formulated by changing an inequality (particular) to an equality (universal), or an equality (universal) to an inequality (particular). Thus, the antilogism of the example above is:

antilogism

Now, let us check to see if the antilogism meets the three requirements  mentioned above. As we can see:

  1. There are three equations, namely: propositions (that is, premises) 1 and 2, and 1 inequation (that is, the conclusion).
  2. There is a common term between the equations (universal propositions), which is once negative and once affirmative, namely: antilogism
  3. The other two terms are unchanged in the inequation (conclusion), namely:antilogism

Hence, the above syllogism is valid because it meets the three requirements for antilogism of valid syllogisms.

Let us consider another example.

Example 2:

All professionals are former amateurs.
But some former amateurs are wealthy persons.
Therefore, some wealthy persons are professionals.

antilogism

Let us check whether the syllogism is valid or invalid.

  1. The first requirement is met: the first premise and the conclusion are equalities, that is, universal propositions.
  2. The second requirement is also met: there is a common term between the equations (universal propositions) which is one negative and the other affirmative, namely:
antilogism

3. But the third requirement is not met: the other two terms in the equations (that is, universal propositions), namely

antilogism

are changed in the inequation (that is, particular proposition), namely: F and W.

Hence, the above syllogism is invalid because it does not meet the three requirements for the antilogism of a valid syllogism.

Practice Test

Determine the validity of the arguments or syllogisms below using the antilogism method.

Example 1:

All criminals are guilty of a felony.
But some politicians are guilty of a felony.
Therefore, some politicians are criminals.

Example 2:

Some drivers are traffic law violators.
Some government employees are drivers.
Therefore, some government employees are traffic law violators.

Example 3:

Nurses are sweet lovers.
But Kit is a nurse.
Therefore, Kit is a sweet lover.

An argument consists of two or more propositions offered as evidence for another proposition. In logic and critical thinking, the propositions that are offered as evidence in the argument are called the premises, while the proposition for which the evidence is offered is called the conclusion. Thus, when one gives an argument, one is providing a set of premises as reasons for accepting his or her conclusion. It is important to note that when one gives an argument, one does not necessarily attack or criticize the other. In this way, an argument can also be viewed as a support of someone’s viewpoint.

Types of Arguments

Arguments can either be inductive or deductive. On the one hand, an inductive argument is one in which it is claimed that if the premises are true, then it is probable that the conclusion is true. Hence, even if all of the premises are true, inductive argument or reasoning allows the conclusion to be false. It is also important to note that inductive arguments go from the specific (or particular) to the general. In other words, inductive arguments make broad generalizations from specific observations. Consider the example below.

Example 1:

Ninety percent of the mongo seeds germinate in day 1.
And in day 2, ninety percent of the mongo seeds germinate.
Therefore, ninety percent of the mongo seeds germinate.

Based on the example above, we can also say that inductive arguments are based on observations or experiments.

Deductive arguments, on the other hand, is one in which it is claimed that if the premises are true, then the conclusion is necessarily true. And unlike inductive arguments, deductive arguments proceed from the general to the particular. Thus, a deductive argument or reasoning begins with a general statement or hypothesis and then “examines the possibilities to reach a specific, logical conclusion”. 

Let us consider the example below.

Example 2:

Anybody who kills a person is guilty of a felony.
Jim kills Jack.
Therefore, Jim is guilty of a felony.

Syllogisms

Syllogisms are arguments which consist of three propositions which are so related so that when the first two propositions (that is, premises) are posited as true the third proposition (that is, the conclusion) must also be true. In other words, a syllogism is an argument arranged in a specific manner in such a way that it contains a major premise, minor premise, and a conclusion. Consider the classic example of a categorical syllogism below.

Example 1:

All men are mortal.
Socrates is a man.
Therefore, Socrates is mortal.

How do we determine the major premise, minor premise, and the conclusion?

The major premise is the premise that contains the major term, while the minor premise is the premise that contains the minor term. The conclusion is the third proposition whose meaning and truth are implied in the premises.

How do we determine the major term, minor term, and the middle term?

The major term is the predicate of the conclusion, while the minor term is the subject of the conclusion. The middle term is the remaining term which does not (and cannot) appear in the conclusion.

If we look at the example above, then we know that the major term is “mortal” because it is the predicate of the conclusion and the minor term is “Socrates” because it is the subject of the conclusion. The middle term is “man” or “men” because it is the remaining term and which does not appear in the conclusion. As we can see in the example below, the major term is in red color, the minor term in blue, and the middle term in purple.

Rules of Syllogism

Now that we have presented the key concepts in arguments or syllogisms, let us proceed to the determination of their validity. Logicians have formulated eight (8) rules of syllogism, but of course they can be expanded to 10 or reduced to 6. But let us follow what logicians commonly used, that is, the 8 rules of syllogism. It must be noted that all of the 8 rules of syllogism must be met or satisfied for the argument or syllogism to be valid. If at least one of the 8 rules of syllogism is violated, then the argument or syllogism is invalid.

The 8 rules of syllogism are as follow:

  1. There should only be three terms in the syllogism, namely: the major term, the minor term, and the middle term. And the meaning of the middle term in the firs premise should not be changed in the second premise; otherwise, the syllogism will have 4 terms.
  2. The major and the minor terms should only be universal in the conclusion if they are universal in the premises. In other words, if the major and the minor terms are universal in the conclusion, then they must also be universal in the premises for the argument to be valid. Hence, if the major and minor terms are particular in the conclusion, then rule #2 is not applicable.
  3. The middle term must be universal at least once. Or, at least one of the middle terms must be universal.
  4. If the premises are affirmative, then the conclusion must be affirmative.
  5. If one premise is affirmative and the other negative, then the conclusion must be negative.
  6. The argument is invalid whenever the premises are both negative. This is because we cannot draw a valid conclusion from two negative premises.
  7. One premise at least must be universal.
  8. If one premise is particular, then the conclusion must be particular.

Now, let us apply these 8 rules of syllogism to the arguments below. Let us color the terms to avoid confusion. So, let us assign the color red for the major term, blue for the minor term, and purple for the middle term.

Rule #1 of the 8 rules of syllogismThere should only be three terms in the syllogism, namely: the major term, the minor term, and the middle term.

If we analyze the syllogism above, it would appear that the argument is invalid because it violates rule #1. As we can see, the syllogism above contains 4 terms because the meaning of the middle term “stars” in the first premise is changed in the second premise. The term “stars” in the first premise refers to astronomical bodies or objects, while the term “star” in the second premise refers to celebrities.

Let us consider another example.

As we can see, the syllogism above contains only three terms. Hence, this syllogism is valid in the context of rule #1.

Rule #2 of the 8 rules of syllogism: The major and the minor terms should only be universal in the conclusion if they are universal in the premises.

As we can see, the minor term “terrorist” in the conclusion is universal because of the universal signifier “no”. And since the minor term “terrorist” in the second premise is universal because of the universal signifier “no”, then the syllogism above does not violate rule #2 in the context of the minor term. However, the major term “brilliant” in the conclusion is universal because the proposition is negative; as we already know, the predicate terms of all negative propositions are universal. But if we look at the major term in the first premise, it is particular because, as we already know, the predicate terms of all affirmative propositions are particular. In the end, the syllogism above is invalid because it violates rule #2. This is what logicians call the “fallacy of illicit major”.

Let us consider another example.

Because the major term “creative” in the conclusion is particular, as it is a predicate term of an affirmative proposition, then it does not violate rule #2 because the rule is not applicable here. As we can see, rule #2 is applicable only to universal minor and major terms. But if we check the minor term “weird people” in the conclusion, we learned that it is universal because of the universal signifier all. Since the minor term “weird people” is universal in the conclusion, then it must also be universal in the second premise for this syllogism to be valid. If we look at the minor term in the second premise, it is particular because it is a predicate term of an affirmative proposition. Therefore, in the end, the syllogism above is invalid because it violates rule #2. This is what logicians call the “fallacy of illicit minor”.

Let us consider a valid argument below in the context of rule #2 of the 8 rules of syllogism.

rules of syllogism

The syllogism above is valid in the context of rule #2 of the 8 rules of syllogism because rule #2 is not violated. As we can see, the minor term “Greg” in the conclusion is particular; hence, rule #2 is not applicable. Of course, if a rule is not applicable, then it cannot be violated; and if no rule or law is violated, then the argument is automatically valid. Now, if we look at the major term “liar” in the conclusion, it is universal because it is a predicate term of a negative proposition. But because the minor term “liar” is also universal in the first premise because, again, it is a predicate term of a negative proposition, then this argument satisfies rule #2.

Let us consider another valid argument in the context of rule #2 of the 8 rules of syllogism.

rules of syllogism

Both the minor and major terms in the conclusion of the syllogism above are particular. For this reason, rule #2 of the 8 rules of syllogism is not applicable. Hence, the syllogism is automatically valid in the context of rule #2 of the 8 rules of syllogism.

Rule #3 of the 8 rules of syllogismThe middle term must be universal at least once.

rules of syllogism

The syllogism above is valid in the context of rule #3 of the 8 rules of syllogism because the middle term “beans” in the first premise is universal. In fact, rule #3 of the 8 rules of syllogism asks that at least one of the middle terms must be universal.

Let us consider another example.

rules of syllogism

As we can see, both middle terms in the first and second premise are particular. But because rule #3 of the 8 rules of syllogism asks that at least one of the middle terms must be universal, then the syllogism above is invalid.

Rule #4 of the 8 rules of syllogismIf the premises are affirmative, then the conclusion must be affirmative.

rules of syllogism

The syllogism above is valid because it satisfies rule #4 of the 8 rules of syllogism. As we can see, both premises are affirmative and the conclusion is affirmative.

Let us consider another example.

The syllogism above is invalid because it does not satisfy rule #4 of the 8 rules of syllogism. As we can see, both premises are affirmative, but the conclusion is negative.

Rule #5 of the 8 rules of syllogismIf one premise is affirmative and the other negative, then the conclusion must be negative.

rules of syllogism

The syllogism above is valid in the context of rule #5 of the 8 rules of syllogism. As we can see, the first premise is affirmative, the second premise is negative, and the conclusion is negative.

rules of syllogism

The syllogism above is invalid in the context of rule #5 of the 8 rules of syllogism. As we can see, the first premise is affirmative, the second premise is negative, but the conclusion is affirmative. Hence, it violates rule #5 of the 8 rules of syllogism.

Rule #6 of the 8 rules of syllogismThe argument is invalid whenever the premises are both negative.

Obviously, the above syllogism is invalid because both premises are negative.

Rule #7 of the 8 rules of syllogismOne premise at least must be universal.

The above syllogism is valid in the context of rule #7 of the 8 rules of syllogism because it qualifies the rule. As we can see, the first premise is universal.

Rule #8 of the 8 rules of syllogismIf one premise is particular, then the conclusion must be particular.

The first premise of the above syllogism is particular, and the conclusion is particular too. Therefore, this syllogism is valid in the context of rule #8 of the 8 rules of syllogism.

Categorical Syllogism

categorical syllogism is a simple argument that contains only three categorical propositions, of which the first two are called premises and the third is called the conclusion. Any valid categorical syllogism contains three terms, namely: major term, minor term, and middle term, and each of them must appear exactly but not in the same proposition.

Example 1:

All Filipinos are Asians.
All Cebuanos are Filipinos.
Therefore, all Cebuanos are Asians.

The major term is defined as the predicate of the conclusion. In the example above, the major term is “Asians” because it is the predicate term of the conclusion.

The minor term is the subject term of the conclusion. In the example above, the minor term is “Cebuanos”.

The middle term is the term that occurs in the premises but not in the conclusion. Hence, in the example above, the middle term is “Filipinos”.

In any standard form of a categorical syllogism, the premise that contains the major term must be stated first, which is then called the major premise, followed by the minor premise, which contains the minor term, and then the conclusion.

Going back to the example above, “All Filipinos are Asians” is the premise that contains the major term “Asians”. The proposition “All Cebuanos are Filipinos” is the premise that contains the minor term; hence, it is the minor premise. The conclusion which contains the minor and major terms must be stated last. In short, in a standard form of a categorical syllogism, the order of the premise should be:

However, not all arguments are stated in their standard form. In some cases, the standard order of the terms is not followed, so the structure is hard to determine. Also, it could happen that the basic structure is concealed in a long paragraph so that not only that the structure is difficult to determine but also the validity itself. Logicians solved this problem this way: though the argument is not arranged in a standard form, it is still possible to determine its structure through the clues given by the logical indicators.

Premise indicators: For, Granted that, As indicated by, Since, As shown by, The facts are, Because, For the reason that, Assuming that, Inasmuch as, In view of, and the like.

Conclusion Indicators: Therefore, Thus, Leads to the belief that, Hence, In conclusion, It may be deduced that, So, Proves that, Implies that, Consequently, It follows that, Entails that, For this reason, Indicate that, Then, It is evident that, It must be that, and the like.

Now, if the statement starts with any of the indicators (either premise or conclusion indicators), then it means that the statement that follows is a premise or a conclusion.

Exercises

  1. Some preachers are people of unfailing vigor. No preachers are non-

intellectuals. Therefore, some intellectuals are persons of unfailing vigor.

  1. Some metals are rare and costly substances, but no welder’s materials are non-metals. Hence, some welder’s materials are rare and costly substances.
  2. Some oriental nations are non-belligerents. Since all belligerents are allies either of the United States or of the Soviet Union, and some oriental nations are not allies either of the united states of Soviet Union.
  3. Some non-drinkers are athletes, because no drinkers are persons in perfect physical condition, and some people in perfect physical condition are not non-athletes.
  4. All things inflammable are unsafe things, so all things that are safe are non-explosives, since all explosives are flammable things.
  5. All worldly goods are changeable things, for no wordly goods are things immaterial, and no material things are unchangeable things.
  6. All those who are neither members nor guests of members are those who are excluded; therefore, no conformists are either members or guests of members, for all those who are included are conformists.
  7. All mortals are imperfect beings, and no humans are immortal, whence it follows that all perfect beings are non-humans.
  8. All things are non-irritants; therefore no irritants are invisible objects, because all visible objects are absent things.
  9. All useful things are objects no more than six feet long, since all difficult things to store are useless things, and no objects are six feet long are easy things to store.

Categorical Statements in Traditional Logic

A categorical statement in categorical logic is a statement or proposition that asserts or denies something without qualification. It is a statement or proposition that is not hypothetical. Aristotle divided the categorical statement into two, namely, the subject class and the predicate class.

There are four interpretations in which these two classes can be related to one another. Only four types of propositions must be translated into one of these types, namely:

  1. Every member of one class is also a member of the other class;
  2. No member of one class is a member of another class;
  3. Some members of one class are also members of another class; and
  4. Some members of one class are not members of another class.

A standard way of writing these four types of propositions to illustrate their relationship is as follows:

  1. All men are mortal.
  2. No men are mortal.
  3. Some men are mortal.
  4. Some men are not mortal.

The four categorical statements or propositions above suggest the inclusion or exclusion of one class (subject class) in the other class (predicate class). If it affirms the inclusion of the subject class in the predicate class, it is called an affirmative statement. If it denies the inclusion of the subject class in the predicate class, it is called a negative statement. Furthermore, it the suggestion is total inclusion, it is a universal affirmative statement; if total exclusion, then it is a universal negative statement. If it means only partial inclusion, then it is called a particular affirmative statement; if partial exclusion, it is called a particular negative statement.

Thus, going back to the examples above, we can say that the first categorical statement is universal affirmative because it suggests the total inclusion of the subject class “men” in the predicate class “mortal”. The second example is universal negative because it suggests a total exclusion of the subject class “men” in the predicate class “mortal”. The third example is particular affirmative because it suggests partial inclusion of the subject class “men” in the predicate class “mortal”. And the last example is particular negative because it suggests a partial exclusion of the subject class “men” in the predicate class “mortal”.

Where letter S and P are used to represent the subject and the predicate terms respectively, the examples above can be schematically represented as follow:

It is customary to use the letters A and I to represent the universal and particular statements respectively, taken from the first two vowels of the Latin word Affirmo, which means “I affirm”. The letters E and O are used to represent the universal and particular negative statements respectively, presumed to come from the Latin word Nego, which means “I deny”.

As we may already know, our main goal in logic is to determine the validity of arguments. 

And in categorical logic, we will employ the Eight (8) Rules of Syllogisms for us to be able to determine the validity of an argument. But since the 8 rules of syllogisms talk about the quantity and quality of terms and propositions, then it is but logical enough to discuss the nature of terms and propositions before we delve into the discussion on the 8 rules of syllogisms. In what follows, I will discuss the nature of terms and propositions.

First of all, logicians define a term as an idea expressed in words either spoken or written. Of course, an idea is understood as the mental representation of something. Hence, when one says, for example, “a table”, then we have at term, that is, a “table”.

Classification of Terms

There are four (4) classifications of terms in terms of quantity, namely: singular, collective, particular, and universal.

A singular term is one that stands for only one definite object.

Examples:

1) Table

2) Peter

3) Tree

A collective term is one that is applicable to each and every member of a class taken as a whole but not to an individual taken singly.

Examples:

1) Orchestra

2) Platoon

3) Choir

A particular term is one that refers to an indefinite number of individuals or groups. Some signifiers of a particular term are: some, a number of, several, almost all, a few of, practically all, at least one, not all, and the like. Hence, if a term is signified by at least one of these signifiers, then we conclude that that term is a particular one.

Examples:

1) Some Asians

2) Almost all students

3) Several politicians

A universal term is one that is applicable to each and every member of a class. Some of the signifiers of a universal term are: no, all, each, every, and the like.

Examples:

1) All Asians

2) Every politician

3) No student

A proposition, on the other hand, is a judgment expressed in words either spoken or written. When we say a judgment, it refers to the mental act of affirming or denying something.

Example:

1) President Trump is a good president.

2) President Trump is not a good president.

The first example above is an act of affirmation because the copula (or linking verb) is does not contain a negation sign “not”. The second example is an act of negation because the copula (or linking verb) is contains a negation sign “not”.

Kinds of Propositions used in Logic

There are two types of propositions used in logic, namely, categorical and hypothetical propositions. On the one hand, a categorical proposition is one that expresses an unconditional judgment. For example, we may say “The Japanese people are hard-working.” According to logicians, this proposition is a categorical one because it does not pose any condition. On the other hand, a hypothetical proposition is one that expresses a conditional judgment. For example, we may say “If it rains today, then the road is wet.” Please note that in categorical logic we always use categorical propositions.

Elements of a Categorical Proposition

A categorical proposition has three elements, namely: Subject (S), Copula (C), and Predicate (P).

Example:

terms and propositions

Quantity of a Categorical Proposition

In terms of quantity, a categorical proposition can be classified into two, namely: 1) particular and 2) universal.

A particular proposition is one that contains a particular subject term.

Example:

  1. Some Asians are excellent basketball players.

A universal proposition is one that contains a universal subject term.

Example:

1) All men are mortal.

As we can see, it is the quantity of the subject that determines the quantity of the proposition. Thus, if the subject is particular, then the proposition is particular, and if the subject is universal, then the proposition is universal.

Now if the subject of the proposition does not contain a signifier, then the quantity of the proposition must be based on what the proposition denotes. Consider the example below:

Nuns are girls.

As we can see, the subject of the proposition does not contain a signifier. But if we analyze it, it would become clear that the proposition is universal. This is because there is not at least 1 nun that is not a girl. In other words, all nuns are girls. Let us consider another example:

Americans are rich.

Obviously, the example above denotes particularity because it’s not sound to assume that all Americans are rich. Of course, many Americans are rich, but reason tells us that not all of the Americans are rich. Hence, the above proposition can be translated as follows: “Some Americans are rich”.

Quality of a Categorical Proposition

Categorical propositions can be either affirmative or negative.

A proposition is affirmative if the copula of the proposition does not contain a negation sign “not”.

Example: 1) Some students are brilliant.

A proposition is negative if the copula of the proposition contains a negation sign “not”.

Example: 1) Some students are not brilliant.


Four Basic Types of Categorical Propositions

If we combine the quantity and quality of propositions, the result is the four (4) types of categorical propositions, namely: 1) Universal Affirmative, 2) Universal Negative, 3) Particular Affirmative, and 4) Particular Negative. Logicians use the letter “A” to represent a universal affirmative proposition, “E” for universal negative, “I” for particular affirmative, and “O” for particular negative. Consider the examples below:

Universal Affirmative (A)  : All men are mortal.

Universal Negative (E)      : No men are mortal.

Particular Affirmative (I)   : Some men are mortal.

Particular Negative (O)     : Some men are not mortal.

Distribution of Terms

In a universal proposition, the subject term is distributed, while in a particular proposition subject term is undistributed. And in a negative proposition, the predicate term is distributed while in an affirmative proposition the predicate term remains undistributed. In other words, the subject terms of all universal propositions are always universal, while the subject terms of all particular propositions are always particular. And the predicate terms of all affirmative propositions are always particular, while the predicate terms of all negative propositions are always universal.


Translating Categorical Propositions into their Standard Form:

To avoid confusion when we analyze the 8 rules of syllogisms, it is helpful to translate categorical propositions into their standard form. Below are the standard forms of an A, E, I, and O propositions.

A proposition  : All + subject + copula + predicate

E proposition   : No + subject + copula + predicate

I proposition    : Some + subject + copula + predicate

O proposition  : Some + subject + copula + not + predicate

Examples:

A: Every priest is religious.

Standard form:  All priests are

E: Every priest is not religious.

Standard form:  No priest is religious.

I: Almost all politicians are corrupt.

Standard form:  Some politicians are corrupt.

O: Several politicians are not corrupt.

Standard form:  Some politicians are not corrupt.

Notes in Categorical Logic

Terms, Judgments, and Propositions

Term: an idea expressed in words either spoken or written

Classification of Terms:

Singular : one that stands for only one definite object

  Examples: 
1) Table
2) Socrates
3) Tree

Collective : one that is applicable to each and every member of a class taken as a whole but not to an individual taken singly.

  Examples:

1) orchestra
2) platoon

Particular : one that refers to an indefinite number of individuals or groups. Some signifiers of a particular term: some, a number of, several, almostall, practically all, at least one, a few of, not all, and the like.

  Examples:

1) some Sillimanians
2) almost all students
3) several politicians

Universal : one that is applicable to each and every member of a class. Some signifiers of a universal term: No, All, Each, Every

  Examples:

1) All Sillimanians
2) Every politician

Judgment: the mental act of affirming of denying something.

Proposition: judgment expressed in words either spoken or written.

Example:

1) President Noynoy Aquino is a good president.
2) President Noynoy Aguino is not a good president.

Kinds of Propositions used in Logic

Categorical : a proposition that expresses an unconditional judgment.

  Example: 1) The Japanese people are hard-working. 

Hypothetical : a proposition that expresses a conditional judgment

  Example: 1) If it rains today, then the road is wet.

Elements of a Categorical Proposition

  • Subject (S)
  • Copula (C)
  • Predicate (P)

Quantity of a Categorical Proposition

Particular : one that contains a particular subject term. 

  Example: 1) Some Sillimanians are foreigners.

Universal : one that contains a universal subject term.

  Example: 1) All Filipinos are Asian.

Note: It is the quantity of the subject that determines the quantity of the proposition. Thus, if the subject is particular, then the proposition is particular; if the subject is universal, then the proposition is universal.

Note: If the subject of the proposition does not contain a signifier, the quantity of the proposition must be based on what the proposition denotes.

Quality of a Categorical Proposition

Affirmative : if the copula of the proposition does not contain a negation sign “not

  Example: 1) Some Sillimanians are brilliant.

Negative : if the copula of the proposition contains a negation sign “not

  Example: 1) Some Sillimanians are not brilliant.

Four Basic Types of Categorical Propositions

Universal Affirmative (A) : All men are mortal.

Universal Negative (E) : No men are mortal.

Particular Affirmative (I) : Some men are mortal.

Particular Negative (O) : Some men are not mortal.

Translating Categorical Propositions into their Standard Form:

Standard Forms:  

A proposition : All + subject + copula + predicate

E proposition : No + subject + copula + predicate

I proposition : Some + subject + copula + predicate

O proposition : Some + subject + copula + not + predicate

Examples:

  1. A:  Every priest is religious.

Standard form:  All priests are religious.

  1. E: Every priest is not religious.

Standard form:  No priest is religious.

  1. I: Almost all politicians are corrupt.

Standard form:  Some politicians are corrupt.

  1. O: Several politicians are not corrupt.

Standard form:  Some politicians are not corrupt.

  1. Nuns are girls.

Standard from: All nuns are girls.

  1. Cheaters are not trustworthy.

Standard from: No cheaters are trustworthy.

  1. Fruits are delicious.

Standard form: Some fruits are delicious.

  1. Flowers are not fragrant.

Standard form: Some flowers are not fragrant.

Square of Opposition

Contrary: A E; differ only in quality

Rules: If one of the contraries is true, the other is false.

If one is false, the other is doubtful.

Examples:

1) A:

Argument and Syllogism

Argument: consists of one or more propositions offered as evidence for another proposition

Syllogism: an argument which consists of three propositions which are so related so that when the first two propositions are posited as true, the third proposition must also be true.

Example: All lawyers are professionals.

Some criminals are professionals.

Therefore, some criminals are lawyers.

Elements of a Syllogism:

Major premise: the proposition that contains the major term 

Minor premise: the proposition that contains the minor term 

Conclusion: the third proposition whose meaning and truth are implied in the premise

Terms used in Syllogisms:

Major term (T): the predicate of the conclusion

Minor term (t): the subject of the conclusion

Middle term (M): the remaining term in the syllogism which does not appear in the conclusion

8 Rules of Syllogism: refer to the rules used in determining the validity of an argument

1) There must only be three terms in the syllogism: the major, minor, and middle terms.

2) The major and/or the minor term should only be universal in the conclusion if they are universal in the premises.

3) The middle term must be universal at least once.

4) If both of the premises are affirmative, the conclusion must also be affirmative.

5) If one premise is affirmative and the other negative, the conclusion must be negative.

6) The argument (syllogism) is invalid if both of the premises are negative.

7) One premise at least must be universal.

8) If one premise is particular, the conclusion must also be particular.

Meta-analysis: Meaning and Key Concepts

Gene Glass coined the term meta-analysis to describe an empirically-based research method, which synthesizes research findings from numerous empirical studies. In short, a meta-analysis is a synthesis of results of many researchers about the field or topic of interest.

Meta-analysis had its beginning in the social science literature, but its applicability extends to behavioral and physical sciences research and to any discipline where individual study findings are too meager to test a theory. Meta-analysis can address policy issues. It has also been a popular research methodology.

Meta-analysis is related to the review of related literature presented in research reports. What makes it different from an ordinary literature review is that it is more rigorous and exhaustive and requires the original empirical data or summaries, such as means, standard deviations, and correlation co-efficient.

While a literature review simply reports the results of a study as significant or not, meta-analysis requires statistical analysis of original data from the studies being integrated. The real strength of meta-analysis lies in its ability to relate conditions that vary across studies to outcomes. For example, Gene Glass and Mary Smith made a meta-analysis of 375 psychotherapy outcome studies and calculated 833 effects. They found a mean effect size of 68 which indicates that the average treated group was two-thirds of a standard deviation better than its control group. Furthermore, 88% of the effects were positive, showing that most treatment groups exceeded their respective control groups on all kinds of outcomes.

Quantitative Methods and Meta-analysis

Quantitative meta-analysis employs quantitative methodology similar to that used in the primary researches that are being integrated. Statistical significance and estimation of effect size provide summaries of study in quantitative integrated reviews. As pointed by R. Rosenthal, the general relationship between tests of significance and effect size is given by the relation: Test statistics is a product of size of effect and sample size.

Effect is determined by dividing the control and experimental group difference by the standard deviation of the control group (the standard deviation being presumed to have been unaffected by treatment). The result is similar to a Z score. This results in standardized measures of effect for comparability of results across studies. The information from each study is presented as the number of standard deviations by which the experimental group exceeds the control group. Estimation of effects is difficult if standard deviations and means are not available. One course of action is to write the authors and request for these data. The other alternative is to estimate effects from other statistics presented. A method of estimating effects, given the t value and the sample sizes of the control and the experimental groups (assuming that the variance of the control group is unaffected by the treatment) is given by Rosenthal and Rubin:

Effects may also be computed from reported correlation coefficient, but there is a need for transformations to produce comparable correlation statistics.

Other standard quantitative techniques used in meta-analysis include: traditional vote counting, methods for testing the statistical significance of combined results and statistical methods based on vote counts, omnibus combined significance tests, Rosenthal’s fail-safe number, and the possibility of combining raw data, and testing variation among effect sizes, analogues to the ANOVA and regression analysis for effect sizes, and the use of conventional statistical methods like ANOVA and regression analysis with effect sizes or correlations. Estimators of effect size may be adjusted for sources of bias, and correlations may be transformed to standard mean differences.

R. Rosenthal provides dear explanations of how to conduct tests of differences among research results. These include methods for research results represented as effects of magnitude, as well as those represented as p-value or significance level (that is, terms of omnibus procedures for testing differences among the results of three or more studies, as well as procedures for testing specific contrasts among research results), procedures for combining estimates, and standard errors for optimally weighted estimates.

It must be noted that research integration does not have to be solely quantitative (that is, the use of quantitative such as tests of combined significance) or qualitative (that is, the use of purely narrative procedures) because it might be necessary to combine quantitative and qualitative information such as narrative information in quantitative studies, case studies, expert judgment, and narrative research reviews.

H. Cooper delineates five stages in doing a meta-analysis, namely, 1) problem formulation (that is, deciding about what questions or hypotheses to address and what evidence needs to be included in the review), 2) data collection (that is, specification of procedures to be used in finding relevant evidence), 3) data evaluation (that is, deciding about which of the retrieved data should be included in the review), 4) analysis and interpretation (that is, selection of procedures for making inferences about the literature as a whole, and 5) public presentation (that is, deciding what information should be included in the report of the integrated review). On the other hand, R. Light and D. Pillemer give the following strategy in doing a meta-analysis: 1) formulation of the precise question, 2) exploration of available information, 3) selection of studies, 4) determination of the generality of conclusions, and 5) determination of the relationships between study characteristics and study outcomes.

H. Cooper suggests the following basic structure in writing the research report of a meta-analysis: 1) introduction, 2) methods, 3) results, and 4) discussion. These are actually the basic sections of primary research reports.

Validity, Reliability, and other Issues

Threat to validity may arise from nonrepresentative sampling, subjective decisions that can lead to procedural variations that can affect the outcomes of the research review, and the “file drawer” problem in combined significance testing. The file drawer problem has something to do with the effects of selective sampling in doing an integrative research.

Studies that report larger effects or more statistically significant results are more likely to get published. If these studies are sampled in an integrative review, the effect of this selective sampling will seriously distort the conclusions of the integrated review. Mary Smith, for example, reported that published journal results in a meta-analytic study of sex bias in counseling differed from dissertations, with journal results showing bias (average effect of .22) and dissertations showing the opposite (-.24). R. Rosenthal also mentioned about these drawers being filled with studies of no significant difference. He provides a procedure for determining the number of null results that would be necessary to overturn the conclusion, based on a significant finding from a combined-significance test. If only a few unretrieved null results could reduce the combined significance test result to insignificance, then the file drawer threat must be seriously entertained as a rival hypothesis. If the number of null results required is implausibly large, the finding is robust against the file drawer threat.

Another problem confronting meta-analysts is the “apples and oranges” problem. This refers to the inadvertent comparison of studies that are not comparable. Gene Glass suggests inclusion of all research bearing on the topic of interest, carefully categorizing it so that comparisons among various categories will yield important differences in quality should they exist.

Experts differ in their opinion regarding what to include in a meta-analytic study. R. Light and M. Smith suggest stiff criteria for inclusion of research in meta-analysis. Other scholars, such as Gene Glass, insist on including all relevant literature so that statistical analysis can assist in decisions about the use of various classes of studies. V. Wilson and Putnam found a large and consistent difference between randomized and nonrandomized studies of pretest sensitization, which lead them to ignore nonrandomized studies in further meta-analyses. The experimental and logical evidence for pretest effect was lacking in the latter studies. On the other hand, M. Smith and G. Glass found no differences between randomized and nonrandomized psychotherapy outcome studies; hence, they aggregated the two in their latter syntheses.

Criticisms of Meta-analysis

R. Rosenthal gives six classes of criticisms of meta-analysis: those that concern sampling bias, the loss of information inherent in meta-analysis, heterogeneity of method or of study quality, problems of dependence between and within studies, the purported exaggeration of significance in meta-analysis, and the problem of determining the practical importance of effect size.

What is a Research Gap and How to Identify it?

This lecture will briefly discuss the meaning, nature, and dynamics of a research gap. In particular, it will address the following questions:

1) What is a research gap?

2) What is the importance of identifying the research gap?

3) How to identify a research gap?

In addressing these three important questions, this lecture will give more weight on the third question. This is because many fledgling scholars and master’s and doctoral students struggled in identifying the gap in their research, thesis, or dissertation. Hence, it is the goal of this lecture to spare them the unnecessary burden of circling the mountain several times before getting to the top.

So, what is a research gap?

Understood more broadly, a research gap is the problem that researchers would want to see addressed in the research. As the name suggests, it is the gap that researchers fill with their proposed research project.

Hence, a research gap is “what is missing” or “what is not addressed” in the current state of knowledge. Put simply, a research gap is the question or problem that has not been answered in your area of specialization. For this reason, the research gap establishes “the need” or the “importance, urgency, and necessity” of your proposed research project, thesis, or dissertation.

This explains why all types of research always begin with a research gap. Indeed, no research activity is possible without the research gap.

Please note that this is what experienced reviewers or thesis/dissertation panel members are looking for during thesis or dissertation proposal defense. Thus, if your proposed thesis or dissertation does not have or does not clearly articulate the research gap, then chances are your thesis or dissertation proposal will be rejected and you have to do your research again from scratch.

This is the problem with many master’s and doctoral students when they write their thesis or dissertation. In most cases, because they are inexperienced researchers and, sometimes, they do not consult their thesis/dissertation adviser regularly, they simply start with a research aim and thought that it’s already the research gap. But the research gap is not the same with the research aim. And in some cases, master’s and doctoral students just copied or patterned their thesis or dissertation on previous researches.

Let us consider the example below.

Supposed the working title of the thesis/dissertation proposal is “Imposed Career Study among University Students in Hong Kong”. With this title, we can have the following research aim:

“The proposed research aims to determine the lived experiences of those students who were just forced to take a certain career course according to the wishes of their parents or significant others and how it affects the psycho-emotional and social wellbeing of these students.”

Again, many master’s and doctoral students thought that the aim is already the problem or the research gap of the proposed research project. But as already mentioned, it is not.

So, what could possibly be the research gap of the above proposed research project?

Based on the above research aim, we can have, for example, the idea:

“The researcher may have learned from experience or through literature review that there are university students in Hong Kong who were just forced to take certain career course according to the wishes of their parents or significant others and that these students were devastated and became rebellious in schools. For this reason, these students may become social delinquents in the future. Now, based on the researcher’s initial review of related literature, it was found out that no study has been conducted on the topic.”

As we can see, the problem is that there are university students in Hong Kong who were just forced to take a certain career course according to the wishes of their parents or significant others. As a result of being just forced to take a certain career course, these students have become devastated and rebellious, which in turn will make them as social delinquents in the future. Also, there has been no study conducted on this topic in Hong Kong. This is exactly what we meant by a “research gap”. This is “what is missing” or “what has not been addressed” in the current state of knowledge in this field. And with this research gap, we can now formulate the research aims, which reads:

“The proposed research aims to determine the lived experiences of those students who were just forced to take a certain career course according to the wishes of their parents or significant others and how it affects the psycho-emotional and social wellbeing of these students.”

If one may ask why the need for this study, then the researcher may add:

“The researcher argues that there is a need to determine the lived experiences of these students so that we can create a career decision-making program as an alternative in addressing the problem.”

As we can see, identifying the research gap and articulating it in the “background” or “rationale” of the study is important not only because it will spare the researcher the unnecessary toil of making major revision, but also because it will make the research publishable. For sure, if the researcher clearly identifies the research gap and articulates it in the background of the study, the reviewers or thesis defense panel members will be able to conclude right away that the proposed research project is unique and original because it is not a duplication of what have been done in the past. This will also send a message to the reviewers or thesis defense panel members that the researcher has deep knowledge of the topic under investigation. As is well known, finding original and innovative topics in the chosen field as well as identifying and articulating the research gap is never an easy feat.

Now that we have briefly discussed the nature and meaning of a research gap and its importance, the next question is how do we identify the research gap?

For experienced researchers, because they already have broad and deep knowledge on their chosen field of specialization, they can easily identify a research gap. However, for fledgling scholars as well as master’s and doctoral students, as already mentioned, identifying a research gap is never an easy feat. But the application of some proven techniques will somehow help ease the process. 

Let me briefly discuss the three important techniques in identifying a research gap. 

Of course, there are a number of techniques on how to identify a research gap, but the three points introduced below are the most effective ones. 

First, when thinking of a topic in your field of specialization, it would greatly help if you start with something that you are passionate about, something that would seem like second skin to you. 

For some obvious reason, being passionate at something makes you push yourself harder, and despite working long hours on it, you will still manage to smile. In fact, if you love what you are doing, then long and hard labor is turned into “play”. Hence, despite the hardships, you keep doing your research because you enjoyed it. 

Of course, starting with something that you are passionate about in relation to identifying a research gap involves “choosing a particular topic” in your discipline or field of specialization. For instance, if your discipline is “education”, then you might be passionate about doing research on “teachers’ burnout level”, “philosophy of education”, “critical pedagogy”, or “lived experiences of teachers handling subjects not in line with their field of specialization”.

If your discipline is psychology, then you might be passionate about doing research on “social cognition”, “social control”, “racism”, “verbal communication”, or even “attraction, romance, and love”.

Second, once you have chosen a topic that you are passionate about, the next step is to “determine the mega trends and recent debates” in your discipline or field of specialization. This is important because once you know the mega trends or recent debates in your discipline or field of specialization, you can easily identify what have and have not been done in your discipline.

Determining the mega trends and recent debates in your discipline is also important because it will ensure that your research is timely and necessary. You have to remember that you do not do research for the sake of doing research, of completing a master’s or doctoral degree. You do research because there is a problem that needs to be addressed. Hence, a particular research is timely if the topic is one of the mega trends and recent debates in the field and it is necessary if it attempts to address a serious problem that requires urgent consideration.

Of course, determining the mega trends and recent debates in your discipline implies doing a literature review. This leads us to the third and last point.

Needless to say, you need to review recent literature in your chosen discipline or field of specialization so you may know what scholars have done so far. In this way, you will be able to identify possible gaps that you can fill in. For example, if your discipline is anthropology and you are passionate about doing research on the indigenous peoples in Southeast Asia, then you need to review literature on indigenous peoples in Southeast Asia in the last, say, 3-5 years.

Now, suppose several famous scholars on indigenous peoples in Southeast Asia have published on “the marginalization” of the Dayak indigenous people in Borneo, then this is precisely one of the mega trends and recent debates in this field of specialization.

Suppose you are interested in joining the discussion or debate on this topic, then you need to identify what have not been done by those scholars. It could be a problem that remains unsolved or a new insight that may help shed light on the issue being debated upon.

How do you do this?

Suppose there are 5 famous scholars working on the topic “the marginalization” of the indigenous peoples in Southeast Asia, particularly the Dayak indigenous people in Borneo. What you need to do now is review these pieces of literature and identify their concepts and arguments. For instance, you may say:

Scholar 1, in her work titled “Modernism and the Dayak People of Borneo”, says that the Dayak indigenous peoples in Borneo have been pushed further to the periphery by the forces of modernity, such as consumerism. 

Scholar 2, in his work titled “Militarism in Borneo”, argues that one of the causes of the marginalization of the Dayak people in Borneo is the imposition of militarization in the island. 

Scholar 3, in her work titled “The Resiliency of the Dayak People”, says that despite the constant presence of social forces that marginalized the Dayak people, the researcher found out that the Dayak people are very resilient. In fact, they have overcome every challenge that they faced and easily returned to their normal life. 

Scholar 4, in his work titled “Different Faces of Marginalization in Borneo”, says that the Dayak people have been marginalized by different forces of globalization, such as the logging and mining companies. 

Lastly, scholar 5, in her work titled “Rights, Recognition, and the Dayak People”, narrates not only how the Dayak people have been marginalized by the forces of globalization but also the basic and inalienable rights of the Dayak people.

Now, after reviewing these important pieces of literature about the marginalization of the Dayak people, you realized that no scholar on the Dayak people, so far as you know, has done research on “the way in which the Dayak people resisted any forms of marginalization”. 

As you can see, this issue is one of the important topics on the debate about the marginalization of the Dayak people in Borneo, yet no scholar has brought this issue on the table. Hence, this could be a possible “gap” in this area of specialization that you can fill in with your research on the way in which the Dayak people resisted any forms of marginalization. 

With this “research gap”, you may work, for example, on “the Dayak people’s struggle for recognition of their rights to ancestral domain”. Your working title may read:

Self-Determination and the Dayak People’s Struggle for Recognition” 

And your research’s main goal reads: 

This proposed thesis aims to explore how the Dayak people in Borneo resisted the forces of globalization that marginalized them.” 

So, that’s what a research gap is and how to identify it.

Please note, however, that what I shared above are just some of the techniques on how to identify a research gap. There are other techniques that might help you in identifying a research gap or you may want to develop your own. What is important at this point is that through the discussion above you have now a basic understanding of what a research gap is and how to identify it. 

And lastly, please note that the principles that we applied in the above discussion on how to identify a research gap can be applied to all disciplines, be they social sciences, humanities, natural sciences, education, engineering, mathematics, or psychology.

Background of the Study in Research:
Definition and the Core Elements it Contains

Before we embark on a detailed discussion on how to write the background of the study of your proposed research or thesis, it is important to first discuss its meaning and the core elements that it should contain. This is obviously because understanding the nature of the background of the study in research and knowing exactly what to include in it allow us to have both greater control and clear direction of the writing process.

So, what really is the background of the study and what are the core elements that it should contain?

The background of the study, which usually forms the first section of the introduction to a research paper or thesis, provides the overview of the study. In other words, it is that section of the research paper or thesis that establishes the context of the study. Its main function is to explain why the proposed research is important and essential to understanding the main aspects of the study.

The background of the study, therefore, is the section of the research paper or thesis that identifies the problem or gap of the study that needs to addressed and justifies the need for conducting the study. It also articulates the main goal of the study and the thesis statement, that is, the main claim or argument of the paper.

Given this brief understanding of the background of the study, we can anticipate what readers or thesis committee members expect from it. As we can see, the background of the study should contain the following major points:

1) brief discussion on what is known about the topic under investigation;
2) An articulation of the research gap or problem that needs to be addressed;
3) What the researcher would like to do or aim to achieve in the study (research goal);
4) The thesis statement, that is, the main argument or contention of the paper (which also serves as the reason why the researcher would want to pursue the study);
5) The major significance or contribution of the study to a particular discipline; and
6) Depending on the nature of the study, an articulation of the hypothesis of the study.

Thus, when writing the background of the study, you should plan and structure it based on the major points just mentioned. With this, you will have a clear picture of the flow of the tasks that need to be completed in writing this section of your research or thesis proposal.

Now, how do you go about writing the background of the study in your proposed research or thesis?

The next lessons will address this question.

How to Write the Opening Paragraphs of the Background of the Study?

To begin with, let us assume that you already have conducted a preliminary research on your chosen topic, that is, you already have read a lot of literature and gathered relevant information for writing the background of your study. Let us also assume that you already have identified the gap of your proposed research and have already developed the research questions and thesis statement. If you have not yet identified the gap in your proposed research, you might as well go back to our lesson on how to identify a research gap.

So, we will just put together everything that you have researched into a background of the study (assuming, again, that you already have the necessary information). But in this lesson, let’s just focus on writing the opening paragraphs.

It is important to note at this point that there are different styles of writing the background of the study. Hence, what I will be sharing with you here is not just “the” only way of writing the background of the study. As a matter of fact, there is no “one-size-fits-all” style of writing this part of the research or thesis. At the end of the day, you are free to develop your own. However, whatever style it would be, it always starts with a plan which structures the writing process into stages or steps. The steps that I will share with below are just some of the most effective ways of writing the background of the study in research.

So, let’s begin.

It is always a good idea to begin the background of your study by giving an overview of your research topic. This may include providing a definition of the key concepts of your research or highlighting the main developments of the research topic.

Let us suppose that the topic of your study is the “lived experiences of students with mathematical anxiety”.

Here, you may start the background of your study with a discussion on the meaning, nature, and dynamics of the term “mathematical anxiety”. The reason for this is too obvious: “mathematical anxiety” is a highly technical term that is specific to mathematics. Hence, this term is not readily understandable to non-specialists in this field.

So, you may write the opening paragraph of your background of the study with this:

“Mathematical anxiety refers to the individual’s unpleasant emotional mood responses when confronted with a mathematical situation.”

Since you do not invent the definition of the term “mathematical anxiety”, then you need to provide a citation to the source of the material from which you are quoting. For example, you may now say:

“Mathematical anxiety refers to the individual’s unpleasant emotional mood responses when confronted with a mathematical situation (Eliot, 2020).”

And then you may proceed with the discussion on the nature and dynamics of the term “mathematical anxiety”. You may say:

“Lou (2019) specifically identifies some of the manifestations of this type of anxiety, which include, but not limited to, depression, helplessness, nervousness and fearfulness in doing mathematical and numerical tasks.”

After explaining to your readers the meaning, nature, and dynamics (as well as some historical development if you wish to) of the term “mathematical anxiety”, you may now proceed to showing the problem or gap of the study. As you may already know, the research gap is the problem that needs to be addressed in the study. This is important because no research activity is possible without the research gap.

Let us suppose that your research problem or gap is: “Mathematical anxiety can negatively affect not just the academic achievement of the students but also their future career plans and total well-being. Also, there are no known studies that deal with the mathematical anxiety of junior high school students in New Zealand.” With this, you may say:

“If left unchecked, as Shapiro (2019) claims, this problem will expand and create a total avoidance pattern on the part of the students, which can be expressed most visibly in the form of cutting classes and habitual absenteeism. As we can see, this will negatively affect the performance of students in mathematics. In fact, the study conducted by Luttenberger and Wimmer (2018) revealed that the outcomes of mathematical anxiety do not only negatively affect the students’ performance in math-related situations but also their future career as professionals. Without a doubt, therefore, mathematical anxiety is a recurring problem for many individuals which will negatively affect the academic success and future career of the student.”

Now that you already have both explained the meaning, nature, and dynamics of the term “mathematical anxiety” and articulated the gap of your proposed research, you may now state the main goal of your study. You may say:

“Hence, it is precisely in this context that the researcher aims to determine the lived experiences of those students with mathematical anxiety. In particular, this proposed thesis aims to determine the lived experiences of the junior high school students in New Zealand and identify the factors that caused them to become disinterested in mathematics.”

Please note that you should not end the first paragraph of your background of the study with the articulation of the research goal. You also need to articulate the “thesis statement”, which usually comes after the research goal. As is well known, the thesis statement is the statement of your argument or contention in the study. It is more of a personal argument or claim of the researcher, which specifically highlights the possible contribution of the study. For example, you may say:

“The researcher argues that there is a need to determine the lived experiences of these students with mathematical anxiety because knowing and understanding the difficulties and challenges that they have encountered will put the researcher in the best position to offer some alternatives to the problem. Indeed, it is only when we have performed some kind of a ‘diagnosis’ that we can offer practicable solutions to the problem. And in the case of the junior high school students in New Zealand who are having mathematical anxiety, determining their lived experiences as well as identifying the factors that caused them to become disinterested in mathematics are the very first steps in addressing the problem.”

If we combine the bits and pieces that we have written above, we can now come up with the opening paragraphs of your background of the study, which reads:

As we can see, we can find in the first paragraph 5 essential elements that must be articulated in the background of the study, namely:

1) A brief discussion on what is known about the topic under investigation;
2) An articulation of the research gap or problem that needs to be addressed;
3) What the researcher would like to do or aim to achieve in the study (research goal);
4) The thesis statement, that is, the main argument or claim of the paper; and
5) The major significance or contribution of the study to a particular discipline. So, that’s how you write the opening paragraphs of your background of the study. The next lesson will talk about writing the body of the background of the study.

How to Write the Body of the Background of the Study?

If we liken the background of the study to a sitting cat, then the opening paragraphs that we have completed in the previous lesson would just represent the head of the cat.

This means we still have to write the body (body of the cat) and the conclusion (tail). But how do we write the body of the background of the study? What should be its content?

Truly, this is one of the most difficult challenges that fledgling scholars faced. Because they are inexperienced researchers and didn’t know what to do next, they just wrote whatever they wished to write. Fortunately, this is relatively easy if they know the technique.

One of the best ways to write the body of the background of the study is to attack it from the vantage point of the research gap. If you recall, when we articulated the research gap in the opening paragraphs, we made a bold claim there, that is, there are junior high school students in New Zealand who are experiencing mathematical anxiety. Now, you have to remember that a “statement” remains an assumption until you can provide concrete proofs to it. This is what we call the “epistemological” aspect of research. As we may already know, epistemology is a specific branch of philosophy that deals with the validity of knowledge. And to validate knowledge is to provide concrete proofs to our statements. Hence, the reason why we need to provide proofs to our claim that there are indeed junior high school students in New Zealand who are experiencing mathematical anxiety is the obvious fact that if there are none, then we cannot proceed with our study. We have no one to interview with in the first. In short, we don’t have respondents.

The body of the background of the study, therefore, should be a presentation and articulation of the proofs to our claim that indeed there are junior high school students in New Zealand who are experiencing mathematical anxiety. Please note, however, that this idea is true only if you follow the style of writing the background of the study that I introduced in this course.

So, how do we do this?

One of the best ways to do this is to look for literature on mathematical anxiety among junior high school students in New Zealand and cite them here. However, if there are not enough literature on this topic in New Zealand, then we need to conduct initial interviews with these students or make actual classroom observations and record instances of mathematical anxiety among these students. But it is always a good idea if we combine literature review with interviews and actual observations.

Assuming you already have the data, then you may now proceed with the writing of the body of your background of the study. For example, you may say:

“According to records and based on the researcher’s firsthand experience with students in some junior high schools in New Zealand, indeed, there are students who lost interest in mathematics. For one, while checking the daily attendance and monitoring of the students, it was observed that some of them are not always attending classes in mathematics but are regularly attending the rest of the required subjects.”

After this sentence, you may insert some literature that will support this position. For example, you may say:

“As a matter of fact, this phenomenon is also observed in the work of Estonanto. In his study titled ‘Impact of Math Anxiety on Academic Performance in Pre-Calculus of Senior High School’, Estonanto (2019) found out that, inter alia, students with mathematical anxiety have the tendency to intentionally prioritize other subjects and commit habitual tardiness and absences.”

Then you may proceed saying:

“With this initial knowledge in mind, the researcher conducted initial interviews with some of these students. The researcher learned that one student did not regularly attend his math subject because he believed that he is not good in math and no matter how he listens to the topic he will not learn.”

Then you may say:

“Another student also mentioned that she was influenced by her friends’ perception that mathematics is hard; hence, she avoids the subject. Indeed, these are concrete proofs that there are some junior high school students in New Zealand who have mathematical anxiety. As already hinted, “disinterest” or the loss of interest in mathematics is one of the manifestations of a mathematical anxiety.”

If we combine what we have just written above, then we can have the first two paragraphs of the body of our background of the study. It reads:

“According to records and based on the researcher’s firsthand experience with students in some junior high schools in New Zealand, indeed there are students who lost interest in mathematics. For one, while checking the daily attendance and monitoring of the students, it was observed that some of them are not always attending classes in mathematics but are regularly attending the rest of the required subjects. As a matter of fact, this phenomenon is also observed in the work of Estonanto. In his study titled ‘Impact of Math Anxiety on Academic Performance in Pre-Calculus of Senior High School’, Estonanto (2019) found out that, inter alia, students with mathematical anxiety have the tendency to intentionally prioritize other subjects and commit habitual tardiness and absences.

With this initial knowledge in mind, the researcher conducted initial interviews with some of these students. The researcher learned that one student did not regularly attend his math subject because he believed that he is not good in math and no matter how he listens to the topic he will not learn. Another student also mentioned that she was influenced by her friends’ perception that mathematics is hard; hence, she avoids the subject. Indeed, these are concrete proofs that there are some junior high school students in New Zealand who have mathematical anxiety. As already hinted, “disinterest” or the loss of interest in mathematics is one of the manifestations of a mathematical anxiety.”

And then you need validate this observation by conducting another round of interview and observation in other schools. So, you may continue writing the body of the background of the study with this:

“To validate the information gathered from the initial interviews and observations, the researcher conducted another round of interview and observation with other junior high school students in New Zealand.”

“On the one hand, the researcher found out that during mathematics time some students felt uneasy; in fact, they showed a feeling of being tensed or anxious while working with numbers and mathematical problems. Some were even afraid to seat in front, while some students at the back were secretly playing with their mobile phones. These students also show remarkable apprehension during board works like trembling hands, nervous laughter, and the like.”

Then provide some literature that will support your position. You may say:

“As Finlayson (2017) corroborates, emotional symptoms of mathematical anxiety involve feeling of helplessness, lack of confidence, and being nervous for being put on the spot. It must be noted that these occasionally extreme emotional reactions are not triggered by provocative procedures. As a matter of fact, there are no personally sensitive questions or intentional manipulations of stress. The teacher simply asked a very simple question, like identifying the parts of a circle. Certainly, this observation also conforms with the study of Ashcraft (2016) when he mentions that students with mathematical anxiety show a negative attitude towards math and hold self-perceptions about their mathematical abilities.”

And then you proceed:

“On the other hand, when the class had their other subjects, the students show a feeling of excitement. They even hurried to seat in front and attentively participating in the class discussion without hesitation and without the feeling of being tensed or anxious. For sure, this is another concrete proof that there are junior high school students in New Zealand who have mathematical anxiety.”

To further prove the point that there indeed junior high school students in New Zealand who have mathematical anxiety, you may solicit observations from other math teachers. For instance, you may say:

“The researcher further verified if the problem is also happening in other sections and whether other mathematics teachers experienced the same observation that the researcher had. This validation or verification is important in establishing credibility of the claim (Buchbinder, 2016) and ensuring reliability and validity of the assertion (Morse et al., 2002). In this regard, the researcher attempted to open up the issue of math anxiety during the Departmentalized Learning Action Cell (LAC), a group discussion of educators per quarter, with the objective of ‘Teaching Strategies to Develop Critical Thinking of the Students’. During the session, one teacher corroborates the researcher’s observation that there are indeed junior high school students in New Zealand who have mathematical anxiety. The teacher pointed out that truly there were students who showed no extra effort in mathematics class in addition to the fact that some students really avoided the subject. In addition, another math teacher expressed her frustrations about these students who have mathematical anxiety. She quipped: “How can a teacher develop the critical thinking skills or ability of the students if in the first place these students show avoidance and disinterest in the subject?’.”

Again, if we combine what we have just written above, then we can now have the remaining parts of the body of the background of the study. It reads:

So, that’s how we write the body of the background of the study in research. Of course, you may add any relevant points which you think might amplify your content. What is important at this point is that you now have a clear idea of how to write the body of the background of the study.

How to Write the Concluding Part of the Background of the Study?

Since we have already completed the body of our background of the study in the previous lesson, we may now write the concluding paragraph (the tail of the cat). This is important because one of the rules of thumb in writing is that we always put a close to what we have started.

It is important to note that the conclusion of the background of the study is just a rehashing of the research gap and main goal of the study stated in the introductory paragraph, but framed differently. The purpose of this is just to emphasize, after presenting the justifications, what the study aims to attain and why it wants to do it. The conclusion, therefore, will look just like this:

“Given the above discussion, it is evident that there are indeed junior high school students in New Zealand who are experiencing mathematical anxiety. And as we can see, mathematical anxiety can negatively affect not just the academic achievement of the students but also their future career plans and total well-being. Again, it is for this reason that the researcher attempts to determine the lived experiences of those junior high school students in New Zealand who are experiencing a mathematical anxiety.”

If we combine all that we have written from the very beginning, the entire background of the study would now read:

If we analyze the background of the study that we have just completed, we can observe that in addition to the important elements that it should contain, it has also addressed other important elements that readers or thesis committee members expect from it.

On the one hand, it provides the researcher with a clear direction in the conduct of the study. As we can see, the background of the study that we have just completed enables us to move in the right direction with a strong focus as it has set clear goals and the reasons why we want to do it. Indeed, we now exactly know what to do next and how to write the rest of the research paper or thesis.

On the other hand, most researchers start their research with scattered ideas and usually get stuck with how to proceed further. But with a well-written background of the study, just as the one above, we have decluttered and organized our thoughts. We have also become aware of what have and have not been done in our area of study, as well as what we can significantly contribute in the already existing body of knowledge in this area of study.

Please note, however, as I already mentioned previously, that the model that I have just presented is only one of the many models available in textbooks and other sources. You are, of course, free to choose your own style of writing the background of the study. You may also consult your thesis supervisor for some guidance on how to attack the writing of your background of the study.

Lastly, and as you may already know, universities around the world have their own thesis formats. Hence, you should follow your university’s rules on the format and style in writing your research or thesis. What is important is that with the lessons that you learned in this course, you can now easily write the introductory part of your thesis, such as the background of the study.
