Test construction and the different types of test questions Test Writing Tests are generally used to determine students’ grades- marks. Help students recognize their strengths and weaknesses in the subject. Help you to access the quality of your teaching and make corrections as you go on. Determine the different learning levels of your students. Common Students Complaints “For hours I studied material that was hardly covered on the exam!” “I didn’t know what was going to be on the exam!” “The test had nothing to do with the classes!” “The test required more skills than those taught in class!” The Learning Cycle 1 Test Plan What objectives do you want to cover? How difficult should you make the test? Who is taking the test? How much time has been provided for testing? How many questions should you have on your test? What type of questions should be included in the test? Questions Sources You own class notes. Particular emphasis on examples and homework well covered. Exercises in the textbook or close related text. Old exams that you had administered in the past. Tests from other instructors. In all cases, revise the items carefully and try to adapt them to your overall teaching approach during the current semester. Planning the Test Step1: Teacher uses course objectives to develop test items by considering the following: 1. The course content or objectives 2. The thinking skills that an instructor wishes to develop in students Bloom’s Taxonomy of Educational Objectives Knowledge 1 Remembering facts, terms, and principles 2 No real understanding is implied at this level Comprehension 3 Relating facts to each other and the generalization of facts 4 Understanding 2 Application 5 Requiring students to use information and ideas and demonstrate that they comprehend this information in a concrete situation Analysis 6 Determining the structure of something; breaking something down into its component parts Synthesis 7 Using a number of facts together to come up with the solution to a problem or the creation of something new (writing) Evaluation 8 Making judgments about the value of material for specified purposes Step 2: Assign relative weights 1-How much time was devoted to each content area during instruction? 2- How much time was devoted to each educational objective during i n s t ru c t i o n ? 2- Which thinking skills were emphasized during instruction? Step 3: Determine the actual number of test items that should be constructed for each category Step 4: Write the actual test items Different types of test Items The focus of this lecture 1. True or False True/False best suited for: 1 knowledge level learning 2 understanding of popular misconceptions 3 when 2 logical responses are possible 3 Advantages 4 Answer many questions in short time 5 Relatively easy to construct Disadvantages 6 Easy; might not discriminate well 7 50-50 chance of correct guess 8 Low in reliability Rules for constructing true/false Rule 1: Avoid double negatives Rule 2: Avoid long or complex statements Rule 3: Specific determiners should be used with caution Rule 4: Include only one central idea is each statement Rule 5: Avoid emphasizing the trivial parts Rule 6: Controversial issues should not be used Rule 7: The test should consist of a greater number of false than true statements 2. Matching Matching best suited for: 1- knowledge level learning of the who, what, when, where variety 2- certain comprehension-level outcomes Types of Matching Terms or words with Definitions Symbols with Names Causes with Effects Problems with Solution Parts with Unit to which they belong Advantages 3 Maximum coverage of knowledge level learning with a minimum of 4 space and preparation time 4 Valuable in subject fields in which a great variety of facts must be learned Disadvantages 5 Time-consuming for the student 6 Not well suited for measuring higher level learning outcomes 3. Multiple-Choice (stem and responses or distractors ) Multiple choice is considered by experts to be the most effective of all the test items. Advantages - It can be used with different knowledge areas and skills -Compromise between essay and true/false -Guessing is reduced -Minimum writing -Wide range of content can be covered on one test Disadvantages - Difficult to construct - quality and quantity of distracters - Time-consuming to construct Forms of Multiple Choice - Question Form - the stem is stated in the form of a question - Incomplete Statement Form - student identifies the remaining part of an incomplete statement - Right Answer Form - student identifies the one and only correct answer -Best Answer Form - student selects the best answer from a series of possible answers. It requires student to use judgment, reasoning, and other types of understanding. 5 The different Alternatives in Multiple Choice items should be -listed on separate lines - indented four spaces from the stem - separated from the stem by a blank line - identified by letters rather than numbers 4. Fill-in the ______, Completion, or Short-answer In Writing Fill-in, Completion or Short-Answer Items, the Item is usually a question or incomplete statement and Response is usually a word, number, short phrase, or sentence. Advantages - Easy to construct - Excellent for who, what, when and where information - Minimizes guessing correctly - Encourages more intensive study by student. Disadvantages -Instructor may use to many since they are easy to construct and therefore, over emphasizes memorization of facts - More than one answer may be correct - Scoring may be difficult 5. Essays Essays are more effective at the higher levels of learning to test synthesis and evaluation. Advantages - Easy to construct - Demonstrates students’ ability to organize knowledge, express opinions and show originality - Minimizes guessing correctly - Stimulates superior study methods. 6 Disadvantages - Limited sampling of the material covered - Inadequate scoring key can make the scoring subjective and unreliable - Scoring may be extremely time-consuming Extended Response Essay Gives the student a great deal of freedom in how to respond to the question Restricted Response Essay - Places limits or boundaries on how the student should respond - Allows the scorer to be more consistent - Question is stated more clearly Rules for Constructing Essay Questions Rule 1: Use essays to measure analysis, synthesis, and evaluation. Rule 2: Provide reasonable time limits for each question. Rule 3: Avoid permitting students a choice of questions. Rule 4: Be sure essay questions have a definitive task. 1 Underline critical words such as “compare,” “contrast,” “criticize,” and “evaluate.” 2 Break the question down into the major areas to be covered. Rule 5: Score restricted response answers by the “checklist point method” using a model answer as a guide. 1 Write an outline or model answer for each question. 2 Determine how many points are to be assigned to the question as a whole and its various parts. Rule 6: Score the essay without the knowledge of the name of the student. Rule 7: Score all of the students’ answers to one question before moving 7 to the next question. Rule 8: Don’t let scoring be influenced by handwriting, spelling, or neatness. Putting the Test Together: Some Dos and Don’ts 1 Don’t crowd too much material on a page. 2 Do include complete instructions. 3 Don’t make the test too long. 4 Do write “power tests” not “speedy tests.” 5 Do group all items of the same type together. 6 Do announce the dates of major tests. Test Assembly Make an effort to use a typesetting software. Avoid: - Misspelled words and mis-numbered items or pages. - An item split between two pages. - Different page format. - Not to include enough space for constructed response items. Other Considerations Take the test yourself and record time. Students usually need to spend three times the time you spent solving the test. Return the graded exam quickly. Discuss the exam after graded. This is a very valuable learning activity. Show students score distribution in the test. The end Dr Hanaa Al Baz 8
