Ten item discrimination indices, across a variety of item analysis situations, were compared, based on the validities of tests constructed by using each of the indices to select 40 items from a 100-item pool. Item score data were generated by a computer program and included a simulation of guessing. (Author/CTM)

THE THEME OF THIS PROGRAM WAS THE USE OF PROBABILISTIC MODELS AS MEASUREMENT TOOLS FOR EXPERIMENTAL DESIGN IN TEST CONSTRUCTION AND FOR ANALYSIS OF TEST DATA. SOME CENTRAL ISSUES IN THIS FIELD ARE DISCUSSED AND RESOLVED IN THE FIRST FOUR CHAPTERS OF THE REPORT UNDER THE FOLLOWING TITLES--(1) CONTRIBUTIONS TO ITEM SELECTION, (2) CLUSTERING…

The basic concepts, practices, and considerations in assessment are outlined in order to provide the reader with a beginning knowledge of assessment techniques and procedures. Discussion includes the goals of assessment, types of tests, criteria for instrument selection, test construction, data collection procedures, and statistical analysis of…

A void exists between the rapid growth of post-high school trade and technical education and the development of educational management tools for that area. Hoping to help fill this void, this research effort concentrated on the development of psychometric instruments useful in measuring achievements. Trade and technical areas involved in the study…

Three methods of item selection were used to select sets of 38 items from a 50-item verbal analogies test and the resulting item sets were compared for internal consistency, standard errors of measurement, item difficulty, biserial item-test correlations, and relative efficiency. Three groups of 1,500 cases each were used for item selection. First…

This paper reports on an experiment designed to investigate the effect of structural and linguistic variables on level of difficulty in solving arithmetic word problems. Identification of such variables is intended to assist curriculum writers in preparing exercises at a specified level of difficulty for students at various age levels. The study…

This guide presents detailed information concerning the purposes and process of program evaluation, the role of the evaluator, and the development of an evaluation plan or design. Instruction is provided in selecting or developing assessment instruments, collecting and analyzing data, reporting evaluation results and applying the findings. The…

The twofold objective of this book is to enable the teacher of English to speakers of other languages both to improve his own classroom measures and to make sound assessments of standardized tests which he may from time to time be asked to select, administer, and interpret. Chapters 1 and 2 introduce the general purposes and methods of language…

Two types of student response inventories for appraising instruction, the Student Instruction Report (SIR) and the Inventory of Student Perceptions of Instruction (ISPI) were administered to 554 students in 30 classes at two Georgia colleges. Mean responses to items were used in principal components analyses with varimax rotation. The two…

Abstracts are presented of the major conference papers and thematic discussions delivered at the 1978 Measurement and Methodology Conference. The titles of the presentations are: Policy-Responsive Evaluation (Wiley); When Educators Set Standards (Glass); Comments on Wiley and Glass (Schutz); Key Standard-Setting Considerations for Minimal…

This chapter should not only acquaint the reader with the present state of the art on Criterion-Referenced (CR) measurement but also suggest possible directions for further inquiry. The goal of the first part of this chapter is to deal with the definitional dilemma of CR measurement by proceeding from the more traditional view of CR measurement to…
