In April of 1982, the German Federal Armed Forces initiated the first empirical pilot project in the area of computerized adaptive testing (CAT). The configuration of hardware, psychological section, and physiological section is discussed, as well as two current problems (data transfer from the TEST 2000 microcomputer to a large sized computer for…

To date, the majority of computerized adaptive testing (CAT) systems for achievement and aptitude testing have been based on the dichotomous item response models. However, current research with polychotomous model-based CATs is yielding promising results. This study extends previous work on nominal response model-based CAT (NR CAT) and compares…

The DX SYSTEM of Diagnostic Testing is an easy-to-use computerized system for developing and administering diagnostic tests. A diagnostic test measures a student's mastery of a specific domain (skill or content area). It examines the necessary subskills hierarchically from the most to the least complex. The DX SYSTEM features tailored testing with…

A conventional verbal ability test and a Bayesian adaptive verbal ability test were compared using a variety of psychometric criteria. Tests were administered to 550 Marine recruits, half of whom received two 30-item alternate forms of a conventional test and half of whom received two 30-item alternate forms of a Bayesian adaptive test. Both types…

A brief overview of item response theory is provided, and a 186-item bibliography of books and articles on the subject dating from 1953 to June 1989 is presented. The overview includes a definition of the theory, a discussion of its development and application, and comparisons with classical test theory. All publications in the bibliography were…

A computerized flexilevel test was implemented and its ability estimates were compared with those of a Bayesian estimation based computerized adaptive test (CAT) as well as with known true ability estimates. Results showed that when the flexilevel test was terminated according to Lord's criterion, its ability estimates were highly and…

This paper reviews 18 microcomputer software item banks on an individual basis. Software Programs reviewed are AIMS (Academic Instructional Measurement System); CREATE-A-TEST; Exam Builder; Exams and Examiner; MicroCAT; Multiple Choice Files; P.D.Q. Builder; Quiz Rite; Teacher Create Series (5 programs); TAP (Testing Authoring Program); TestBank…

This research program was designed to investigate the applications of item response theory and computerized adaptive testing to the unique problems of the measurement of ability and the measurement of achievement. The research utilized a combination of monte carlo simulation studies and live-testing studies. The research approach for adaptive…

The initial development of a testlet-based algebra test was previously reported (Wainer and Lewis, 1990). This account provides the details of this excursion into the use of hierarchical testlets and validity-based scoring. A pretest of two 15-item hierarchical testlets was carried out in which examinees' performance on a 4-item subset of each…

This final report describes the outcomes of Project MAPS (Monitoring Authentic Problem Solving), a project that developed multimedia computer-managed assessment environments to overcome the barriers educators face in using problem-solving performance assessment (PSPA) with students with disabilities. MAPS software was developed for 6 alternate…

Three study cohorts involving 199 gifted fifth graders, 190 gifted sixth graders, and 683 typical sixth graders were used to construct, validate, and pilot a computerized adaptive math test for placing fifth graders in a middle school mathematics gifted program. Results suggest the adaptive test has potential for talent identification. (Author/CR)

Analysis of patterns in time (APT) is presented as a method for gathering information about observable phenomena so that probabilities of temporal patterns of events can be estimated empirically. APT is illustrated through a classroom study of 25 mentally handicapped students and in a study of 2 computer-based tests. (SLD)

Discussion of computerized adaptive testing focuses on a study of graduate students at Indiana University at Bloomington that examined three kinds of computerized adaptive testing procedures to determine their psychological impact and how they may affect test performance. Previous research is reviewed, and further research is suggested. (28…

Describes the workings of computerized adaptive testing (CAT). Focuses on the key concept of information and then discusses two important components of a CAT system: the calibrated item bank and the testing algorithm. Describes a CAT that was designed for making placement decisions on the basis of two typical test administrations and notes the…

Recent research studies have reported on how novices and experts differ in storing, organizing, and retrieving subject matter knowledge and on how they apply their knowledge to solve new problems. These findings have been integrated and implemented in a computer environment to help novices improve their problem-solving skills. An outline of this…
