Why trialling? Collect data to be analyzed: Do items test what they were meant to test? Do they distinguish between masters or non- masters? Are the ambiguous? Inform about test administration procedures: time instructions answer keys Bank items to generate new tests: determine characteristics of items keep/revise/reject

Psychometric approaches vs. mentalistic approaches empirical validity theoretical validity • concurrent validity • face validity • predictive validity • content validity • construct validity QUANTITATIVE APPROACHES EXAMINE PSYCHOMETRIC PROPERTIES OF THE TEST QUALITATIVE APPROACHES PROVIDE MORE INFORMATION ON TEST CONTENT, TEST TASK PROPERTIES AND TESTTAKING PROCESSES
What is verbal report analysis? a special label used to describe the verbal data gathered a technique that draws inferences about the cognitive processes that produced the verbalization comprised of ‘protocols’ - utterances made by an individual invaluable at the trialling and pretesting stage supplement other quantitative data

Stages in collecting and analyzing verbal reports DATA COLLECTION STAGES • Task identification • Task analysis • Selecting an appropriate procedure • Selecting subjects • Training subjects • Collecting verbal reports • Collecting supplementary data • Transcribing verbal reports DATA ANALYSIS STAGES • Developing an encoding scheme • Segmenting protocols • Encoding protocols • Calculating encoder reliability • Analyzing data Source: Green, A.

Examples of verbal report methodology Cohen (1994) five test-takers 2. a two-part test 3. concurrent reports 4. observe test-takers during the test-taking process 5. give test-takers a questionnaire 6. conduct in the test-takers’ L 1 Buck (1994) 1. six test-takers 2. 54 -item test based on a single listening text 3. 13 short sections, one at a time 4. attend a post-test interview 5. take the test items again 1.
Advantages vs. disadvantages reveals test validity provides direct information has wide application commitment in time disruption of behaviour individual differences

Points to note reveals the dynamics of the test taking processes uncovers students’ unobservable behavior resourceful feedback concerning the mental processes or test-taking strategies complements the analysis generated from quantitative investigation a developing and maturing method
