What are the stages of test construction??? Take a minute and try to think of these stages???
Stages of testing 1- Statement of the problem. • It is important to know what you want and for what purpose. • What kind of test is it?? Achievement, ..Proficiency...)? • What is the purpose of the exam?? (What do you want to know?) • What abilities are to be tested? • How detailed must the results be? (long, short, detailed knowledge language abilities...)
2- Providing a solution to the problem • Writing specifications for the test • Content • You need to decide the potential content of any versions. What to include in the writing of any version of the test. • Operation • The tasks the students should carry out. For example, scan the reading, guess the meaning of the context.
Types of text • You need to relate it to the topic and interest. For example, if it is writing, letters, forms, academic essays. • Addressees • The kinds of people that the student is expected to be able to write or speak to. For example, the people for whom reading and listening materials are primarily intended, for example native speaker university students.
Topics • Topics are selected according to suitability for the students and the type of test. • Format and timing • We need to specify the test structure, including time allocated for each component, item types, and procedures. How many scores should be allocated to each part, how many passages should we include or required. • Scoring procedure • Are you going to score it subjectively or objectively?
3- Writing the test • Sampling • It is important to sample widely and predictably from the whole content. You should not concentrate on areas that are easy to test. You should sample widely and unpredictably.
Item writing and moderations • Of course it is difficult to construct perfect test items. It is normal that some of these items should be rejected, or re-written. We can do this through teamwork and asking colleges. We should be open to accept any criticisms. • Writing the scoring key
Test techniques Definition / conditions • A test technique is a mean of eliciting behavior from students which will tell us about their language abilities. • We need techniques which : • will elicit behavior which indicate the abilities we are interested in. • economical in time and effort . • have beneficial wash back effect
Multiple choice items John has been here ______ half an hour. stem ( complete statement, incomplete statement, question) • during b. for c. while d. since Options ( one correct – distracters) (The distracters should not be too long, nor too difficult)
Advantages of multiple choice items • Scoring is reliable. • Scoring is fast and economical. • The test will be more reliable because we can include more items.
Disadvantages of the multiple choice items • It tests only recognition knowledge. (production vs. receptive skills) e.g. grammar test ?? • Guessing may have a considerable effect on test scores. (33% - four options)
It restricts what can be tested. (distracters may not be available ) • It is difficult to write a successful items. (common mistakes: more than one answer, no correct answer, clues in the option, ineffective distracters) • Backwash might be harmful. (harmful effect on teaching / learning) • Cheating might be facilitated.
How to construct a multiple choice item I ……………………... Here for two years. • had lived • have lived • have been living • had been living • Each multiple choice item should have ONLY ONE answer.
I never knew where ……………. • had the boys gone • the boys have gone • have the boys gone • the boys had gone • One feature at a time should be tested.
Someone who designs houses is a …… • designer • builder • architect • plumber • Each option should be grammatically correct when placed in the stem.
It should be at a level appropriate for the proficiency of the students. • It should be brief and clear as possible.
Exercise • Take a look at these examples and try to figure out if the following items are good multiple choice items. • After the guests .............., I went to bed. • left • had left • have left • would leave
I ................. in the class when it began to rain. • was sit • were sitting • was sitting • sit • The present tax reforms have benefited ............... poor. • that • the • a • this
Cloze test • (Cloze test, C-test , and dictation are used to measure the overall ability in a language) • How to write cloze test • The cloze test involves deleting a number of words in a passage, leaving blanks. • After short lead-in, it is usually every seventh words which are deleted.
Advantages and disadvantages of cloze test • Advantages • Easy to construct, administered and score. • Disadvantages • It is not possible to predict accurately people’s abilities with respect to separate skills. • We need careful selection of texts and some pretesting. • Can not tell us about oral ability.
The C- test • How to write C- test C- Test is a variety of cloze test. Instead of deleting the whole word, the second half only is deleted.
Advantages • Exact scoring is necessary • Shorter texts are possible. • Wide range of topics, styles, and levels of abilities. • It takes little space and less time to complete. Disadvantages • It has a puzzle-like nature. It is harder to read • Correct answer can be found in the surrounding text
Yes/No and True/False items Disadvantage: • Encourage guessing (50%) So..?? We can ask the students to correct the false statement…however. this might be problematic?? 1- writing is not meant to be tested here. (validity problem) 2- difficult to score (reliability and validity)
Short answer items • Advantages: • guessing contributes less to the students’ scores. • it is not restricted by the need of distracters. • cheating is more difficult. • It is easier to write.
Disadvantages: • Responses may take longer, so this might reduce the number of items. • Students has to produce language in order to respond. • Scoring can be invalid or unreliable. • Scoring might take longer.
Gap filling items • It is a valuable technique. • It has the same advantages of the short answer techniques , but with greater control. • However, it does not work well for grammar and vocabulary ..???
