ANSWER TO SELF ASSESSMENT

3.3.2 Supply Test Items

This is the type of test item, which requires the testee to give very brief

answers to the questions. These answers may be a word, a phrase, a

number, a symbol or symbols etc. in order to write effective supply test items, you should make use of these tips; construct the questions so as to be as brief as possible. The questions should be carefully worded so as to require an exact answer. Make sure that the questions have only one

answer each.

Supply test items can be in the form of:

a.

short-answer test items: which requires that the testee should

provide a short answer to the question asked. Example

* Who is the senate president of the Nigerian senate?

*

What is the technical drawing instrument used for measuring

angles?

* The two instruments used for cutting screw threads are tap and

………..

* Which of the energies is used for motion?

b.

Completion test items: which require the testee to provide or

complete one or more missing words in a sentence. Examples

* A triangle with all sides and all angles equal is called

………..

*

The process of splitting a leg of wood into planks is called

………..

* ………. is a special chord passing through the center of circle.

3.3.3 Selection Test Items

This is the type where possible alternatives are provided for the testee to

choose the most appropriate or the correct option.

Can you mention them? Let us take them one by one.

a. True-False: In this type a statement is presented to the testee and he is required to state whether it is true or false, Yes or No, Agree or disagree etc. there are only two options.

Examples: In the statement below, answer true or false if the statement is correct and false if the statement is wrong.

* The Tee Square is used for drawing horizontal lines.

* Wood can be hardened and tempered to improve its qualities.

* Any material which obstruct the flow of magnetic flux is called resistor.

The use of flowing garment in a workshop can cause accident.

b. Multiple choice: this is very useful in measuring students achievement in schools. It is very popular and a widely used type

of objective test items. It has two parts. The first is called the stem or premise, which is the question, while the second is the suggested answers called alternatives, options or choices.

The correct option is the answer or the key while other options

are called distractors or distracters. Now develop an objective item of the multiple choice type and indicate the parts. Before we

give examples of multiple choice items, let us examine the

following tips on how to make good multiple choice items.

*

The stems must be simple and clear.

*

All alternatives should be possible answers, related to the stems but with only one most correct or best answer to the question.

*

The distractors should be as attractive as the key and very

effective in distracting testees who are not sure of the key.

*

To avoid guessing the correct answers should not be positioned in a particular way so as to form a patter. It should be randomly positioned.

*

There should be a minimum of four options for each item. Five options are generally preferred.

*

Avoid as much as possible the options ‘none of the above’, ‘all of the above’ or a combination of options like ‘canded’

You can now construct good multiple choice items using these hints. Let us see some examples.

*

The two forms of oblique projections are:………

a. axonometric and planometric b. cavalier planometric c.cavaliers and cabinet
