Item bias has been a major concern for test developers during recent years. The Mantel-Haenszel statistic has been among the preferred methods for identifying biased items. The statistic's performance in identifying uniform bias in simulated data modeled by producing various levels of difference in the (item difficulty) b-parameter for reference…

This paper highlights the need for a systematic, content aware, and theoretically-based approach to test design. The cognitive components approach is endorsed, and is applied to the development of a computerized perceptual speed test. Psychometric literature is reviewed and shows that: every major multi-factor theory includes a clerical/perceptual…

A method of automatically selecting items for inclusion in a test with constraints on item content and statistical properties was applied to real data. Tests constructed manually from the same data and constraints were compared to tests constructed automatically. Results show areas in which automated assembly can improve test construction. (SLD)

This study was undertaken to determine reliability and validity estimates for a newly developed preschool inventory of cognitive functioning which provides many advantages over traditionally utilized measures. A predominantly pictorial stimulus-psychomotor response set was the format for the test. The test consisted of a series of 61 items divided…

The power of the procedure of W. Stout to detect deviations from essential unidimensionality in two-dimensional data was investigated for minor, moderate, and large deviations from unidimensionality using criteria for deviations from unidimensionality based on prior research. Test lengths of 20 and 40 items and sample sizes of 700 and 1,500 were…

This study reports the preliminary results of a research project that focuses on the development of an abbreviated measure of computer anxiety, the Computer Anxiety Scale (CAS)-Short Form (SF), designed for use with upper elementary and secondary school students. The subjects involved in the study included 1075 students in grades 4 through 12,…

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…

Forty three-option multiple choice (MC) statements on a midterm examination were converted to 120 true-false (TF) statements, identical in content. Test forms (MC and TF) were randomly administered to 50 undergraduates, to investigate the validity and internal consistency reliability of the two forms. A Kuder-Richardson formula 20 reliability was…

To investigate the psychometric feasibility of replacing a paper-and-pencil licensing examination with a computer-administered test, a validity study was conducted. The computer-administered test (Cadm) was a common set of items for all test takers, distinct from computerized adaptive testing, in which test takers receive items appropriate to…

The goal of this study was to assess the relative merit of various ranges and types of response scales in terms of respondent satisfaction and comfort and the nature of the elicited information in a population of seventh grade students. Three versions of an attitudinal questionnaire, each containing the same items but employing a different…

This study investigated the relationships among the symbolic representation of problems given to students to solve, the mental representations they use to solve the problems, and the accuracy of their solutions. Twenty eleventh-grade science students were asked to think aloud as they solved problems on the ideal gas laws. The problems were…

The estimation of the internal consistency of a newly constructed instrument using Cronbach's coefficient alpha is demonstrated. This study sought to determine the relationship, if any, between an individual's cognitive style and the preference for certain kinds of information used in making decisions. Cognitive style was determined with the Myers…

This study used multiple methods to assess basic community needs and attributes of community atmosphere (cohesion, religious involvement, and recreational activities) in two psychometric studies. Part 1 revised self-report community assessment measures, developed multi-item scales for each construct, and tested reliabilities and factor structures…

Sixteen goal-like statements were developed around P. Reed's contention that university-public school partnerships promote interdependence between groups, a balanced exchange of valued commodities, shared decision making, adaptations to inherent barriers, and an enabling support structure. The questionnaire was pilot tested with members of other…

Over 2,000 writing samples were collected from four undergraduate institutions and compared, where possible, with scores on a multiple-choice test. High correlations between ratings of the writing samples and multiple-choice test scores were obtained. Samples contributed substantially to the prediction of both college grades and writing…
