The performance of the following four methodologies for assessing unidimensionality was examined: (1) DIMTEST; (2) the approach of P. W. Holland and P. R. Rosenbaum; (3) linear factor analysis; and (4) non-linear factor analysis. Each method is examined and compared with other methods using simulated data sets and real data sets. Seven data sets,…

In this paper a quadratic curve equating method for different test forms under a random-group data-collection design is proposed. Procedures for implementing this method and related issues are described and discussed. The quadratic-curve method was evaluated with real test data (from two 30-item subtests for a professional licensure examination…

Results obtained using three methods for gathering attitude data were compared. The methods are ranking, paired comparisons, and the Likert-type scale. Three attitude objects, each consisting of five items, were selected or developed for this study. One set had been used with graduate students previously. Participants were 392 students in…

This paper reports the results of using a three-layer backpropagation artificial neural network to predict item difficulty in a reading comprehension test. Two network structures were developed, one with and one without a sigmoid function in the output processing unit. The data set, which consisted of a table of coded test items and corresponding…

The present study examines the influence of judges' item-related knowledge on setting standards for competency tests. Seventeen judges from different professions took a 122-item teacher-certification test in economics while setting competency standards for the test using the Angoff procedure. Judges tended to set higher standards for items they…

This paper explores the effectiveness of the Mantel-Haenszel (MH) statistic in detecting differentially functioning test items when the internal criterion is varied. Using a data set from the 1982 statewide administration of a 150-item life skills examination (the New Mexico High School Proficiency Examination), a randomly selected sample of 1,000…

This instructor's manual provides numerous suggestions for observational activities, out-of-class assignments and evaluative strategies for undergraduate and graduate students, and follows the organization of the textbook, "Applying Educational Psychology in the Classroom." The book is organized into two sections--the instructor's manual and test…

A commonly accepted rule for developing equated examinations using the common-items non-equivalent groups (CINEG) design is that items common to the two examinations being equated should be identical. The CINEG design calls for two groups of examinees to respond to a set of common items that is included in two examinations. In practice, this rule…

The 4th Grade Test (1984) of the Illinois Inventory of Educational Progress includes 18 reading items, 27 geometry items, 31 science items, a 27-item student questionnaire regarding science opinions, and 40 mathematics items. The test booklet only is included here. (PN)

The 11th Grade Test (1984) of the Illinois Inventory of Educational Progress includes 19 reading items, 45 geometry items, 46 science items, a 27-item student questionnaire regarding science opinions, and 49 mathematics items. The test booklet only is included here. (PN)

CSAR (Characteristic Storage And Retrieval) is the name of an interactive item bank system for the storage, retrieval, manipulation, and summarization of information about multiple choice test items. The purpose of the system is to facilitate the test construction process. The system has two main components: one or more item banks and an…

Biology 30 is a 12th-grade science course for students in Alberta, Canada. Intended for administration during June 1989, it contains 70 multiple-choice questions and 7 written-response questions. Two-and-one-half hours are allowed for completing the test. No answer key is included since scoring is done by the provincial education department. The…

Chemistry 30 is a 12th-grade science course for students in Alberta, Canada. This document is the final test for the course. Intended for administration during June 1989, it contains 56 multiple-choice questions and 3 written-response questions. Two-and-one-half hours are allowed for completing the test. No answer key is included since scoring is…

The MDT multi-digit technique, a development in testing technology, is described; and its application to science classrooms is discussed. Some actual materials for use in a cell biology class are included. The primary characteristic of an MDT multi-digit test is a long list of possible responses, with each term marked with a three-digit number…

The results of classifying test items on the basis of their Mantel-Haenszel (MH) alpha estimates were compared to the results of classifying these items using an item response theory (IRT) based procedure involving the comparison of item difficulties in the interest of identifying the alpha value that maximized the decision concordance between the…
