This article examines the potential contribution of latent trait models to the study of intelligence. Nontechnical introductions to both unidimensional and multidimensional latent trait models are given. Multidimensional latent trait models can be used to test alternative multiple component theories of test item processing. (Author/CTM)

Two procedures are presented for detecting violations of the unidimensionality assumption made by latent trait models without requiring factor analysis of inter-item correlation matrices. Both procedures require that departures from unidimensionality be hypothesized beforehand. This is usually possible in achievement tests where several content…

As achievement in basic reading declines, the content validity of tests in special subjects may be reduced because examinees cannot read the test items. This study found that reading ability and item format affected test scores in the area of health science for a sample of high school students. (Author/JKS)

Distinguishing between two types of test questions, constructed-response (essay/completion) and selected-response (multiple-choice/true-false), the author considers both in relation to the specificity of learning outcomes being tested, the use of criterion or norm-referenced measurement, and the formative or summative nature of the evaluation.…

Commenting on the preceding article, pages 8-13 of this journal issue, the author critiques Mason's assessment of the utility of selected-response and constructed-response test questions. (SJL)

A study with 804 undergraduates finds that Minnesota Multiphasic Personality Inventory-2 protocols that contain random responding with an onset after item 370 can be distinguished from protocols with an earlier onset of random responding. Results suggest that protocols with late random responding may be interpretable in terms of basic clinical and…

Four guidelines that make tables more effective data displays are presented. The need for these guidelines and their application are illustrated with data from the National Assessment of Educational Progress (NAEP). A theoretical structure is presented to help develop test items to assess students' proficiency in extracting information from…

This article outlines the advantages and disadvantages of various question types in tests for library classes, including selected-response, constructed-response and alternative-response test items. It examines a test case in which students in a for-credit library course were given a take home quiz with search story problems. Sample "search story"…

Examined effects of item characteristics on cloze text performance. Focus was on the relationship between cloze item characteristics and scoring methods. Item characteristics examined were: content/function words; parts of speech; word frequency; number of occurrences of a word in text; alternative answers; syntactic variation; amount of content;…

The relationship of an expert-system-scored constrained free-response item type to multiple-choice and free-response items was studied using data for 614 students on the College Board's Advanced Placement Computer Science (APCS) Examination. Implications for testing and the APCS test are discussed. (SLD)

A group of eight educators and one law student discusses the most recent changes in the Scholastic Aptitude Test content and format, which will include a reasoning test and a battery of subject tests. Comments focus on general reactions, specific additions and deletions, test bias, implications for admissions, and coaching. (MSE)

Findings of studies examining the effects of presentation media on item characteristics are reviewed. The effect of medium of presentation independent of adaptive methodology in computer-assisted testing was studied through tests of 763 Marine trainees. Conditions necessary for score equivalence between item presentation media are described. (SLD)

Discusses factors that should be considered when designing multiple-choice diagnostic tests for use with microcomputer systems. Item content and characteristics are described, presentation of feedback and results are examined, database management functions are discussed, and benefits for students with learning problems and physically disabled…

Investigates similarities and differences of science and mathematics teachers' teaching practices related to critical thinking. Compares the two groups of teachers in terms of objectives and assessment techniques, teaching preferences, various activities, and use of cooperative groups. Reports the results for all of 53 items.

The modified caution index's use in identifying judges whose patterns of item judgment appear aberrant when compared with the pattern produced by the entire group (N=158) of judges was studied. Effects on test standards and passing rates of removing test standards of these judges were also assessed. (TJH)
