The first college mathematics course a student enrolls in is often affected by performance on a college mathematics placement test. Yet validity evidence of mathematics placement tests remains limited, even for nationally standardized placement tests, and when it is available usually consists of examining a student's subsequent performance in…

Although computerized adaptive tests have enjoyed tremendous growth, solutions for important problems remain unavailable. One problem is the control of item exposure rate. Because adaptive algorithms are designed to select optimal items, they choose items with high discriminating power. Thus, these items are selected more often than others,…

Two quasi-experimental field studies were conducted to evaluate the psychometric equivalence of computerized and paper-and-pencil job satisfaction measures. The present research extends previous work in the area by providing better control of common threats to validity in quasi-experimental research on test mode effects and by evaluating a more…

An algorithm for updating the means of variances of a norm group after each computer-assisted administration of a test is described. The algorithm does not require storage of the whole data set, and provides for unlimited, continuous expansion of the test norms. (Author)

The predictive ability of a mathematics test organized into a branching test for computer-interactive administration was investigated. Twenty-five blocks of five items were used in the branching. Each testee took 25 items, with each subsequent block being determined by prior performance. Results supported the branching technique. (JKS)

The concurrent validity of a computer assisted test construction system designed to measure information in the medical sciences was assessed. Results support the usefulness of the system. (Author/JKS)

Factor analysis was used to determine whether computerized patient management problems had the same factor structure as multiple choice examinations and rating scales. It was determined that the factor structure was similar to the examinations but not the rating scale. (JKS)
