What are the advantage of a subjective type of test over objective type of test?

After reading this article you will learn about:- 1. Meaning of Objective Type Test 2. Merits of Objective Type Test 3. Limitations 4. Construction.

Meaning of Objective Type Test:

Simply, an objective type test is one which is free from any subjective bias either from the tester or the marker. It refers to any written test that requires the examinee to select the correct answer from among one or more of several alternatives or supply a word or two and that demands an objective judgement when it is scored.

Objective-Centered Test/Objective based Test:

When questions are framed with reference to the objectives of instruction, the test becomes objective-based. This type of test may contain essay type and objective type test items.

An essay test may be objective-centered or objective-based, though it may be difficult to score it objectively. An objective type test, on the other hand, can always be scored objectively, though it may not be objective-centered if it is not planned with reference to the objectives of instruction.

Objective-type tests have two characteristics viz.:

1. They are pin-pointed, definite and so clear that a single, definite answer is expected.

2. They ensure perfect objectivity in scoring. The scoring will not vary from examiner to examiner.

Merits of Objective Type Test:

1. Objective type test gives scope for wider sampling of the content.

2. It can be scored objectively and easily. The scoring will not vary from time to time or from examiner to examiner.

3. This test reduces (a) the role of luck and (b) cramming of expected questions. As a result, there is greater reliability and better content validity.

4. This type of question has greater motivational value.

5. It possesses economy of time, for it takes less time to answer than an essay test. Comparatively, many test items can be presented to students. It also saves a let of time of the scorer.

6. It eliminates extraneous (irrelevant) factors such as speed of writing, fluency of expression, literary style, good handwriting, neatness, etc.

7. It measures the higher mental processes of understanding, application, analysis, prediction and interpretation.

8. It permits stencil, machine or clerical scoring. Thus scoring is very easy.

9. Linguistic ability is not required.

Limitations of Objective Type Test:

1. Objectives like ability to organise matter, ability to present matter logically and in a coherent fashion, etc., cannot be evaluated.

2. Guessing is possible. No doubt the chances of success may be reduced by the inclusion of a large number of items.

3. If a respondent marks all responses as correct, the result may be misleading.

4. Construction of the objective test items is difficult while answering them is quite easy.

5. They demand more of analysis than synthesis.

6. Linguistic ability of the testee is not at all tested.

7. Printing cost considerably greater than that of an essay test.

Guidelines for Constructing Better Objective Type Test Items:

To be a good item writer, one should have:

(a) A thorough understanding of the subject matter;

(b) A thorough understanding of the pupils tested;

(c) Perseverance; and

(d) A little creativity to prepare fertile kind of items.

It is of paramount importance for him to be cognizant of the pitfalls involved in writing objective type test items.

We shall now offer some general guidelines for the writing of objective type test items:

1. Each item must be clearly expressed i.e. there must be precision in writing the test items.

2. Test for important facts and knowledge and not for trivial details; e.g.,

(a) Give the name of the ship that Columbus was on when he discovered America.

(b) Give the date (and/or time) when Edison invented the light bulb.

These items test the ability to recall or supple trivial details and therefore are unsound.

3. Avoid ambiguous statements. Each item should be subjected to one and only one interpretation.

Poor:

Rabindranath Tagore wrote Gitanjali in……….. The item is ambiguous because the examinee does not know whether the teacher wants to know the year, the date, the language or the place.

Better:

In which language did Rabindranath Tagore write Gitanjali?

4. Quantitative rather than qualitative words should be used. Words such as few, many, low, high, large, etc. are vague, indefinite, and, therefore, should be avoided.

Poor:

TF Many people are literate in Orissa.

Better:

TF About 85% of the people are literate in Orissa.

5. Use good grammar and sentence structure to improve clarity.

Poor:

TF In a triangle, whose one of the angle’s measure is 90°, the hypotenuse is equal to the square root of the sum of the squares of the other two sides.

Better:

TF In a right-angled triangle, the square on the hypotenuse is equal to the sum of the squares on the other two sides.

6. Avoid lifting statements verbatim from the text-book. The use of text book language in a test encourages a pupil to memorise rather than to understand the subject matter.

7. There should be only one correct answer.

Poor:

Fill in the blank by inserting an operational symbol.

2……… 2 = 4

Here, some students may write +, others may write X.

8. Avoid negative questions whenever possible. An indiscriminate use of the negative should be avoided. It takes more time to answer.

Poor:

TF The longitude of Bombay is not 73°E.

Better:

TF The longitude of Bombay is 73°E.

9. Directions to questions should be specific. Ambiguous wording and double negatives should be avoided in questions.
