The placement and diagnostic tests used in instructional systems designed to be adaptive to the individual learner's characteristics are examined. The necessity of pretesting students before instruction is questioned. According to the author, both the necessity for and the content of the Individually Prescribed Instruction (IPI) type of pretest…

During a three-year project (1977-1980) on computerized adaptive achievement testing, item characteristic curve theory (ICC) and adaptive testing strategies designed almost exclusively for ability testing were applied to achievement testing. Adaptive techniques substantially reduced test length without reducing quality, when applied to three…

Detecting differential item functioning (DIF) on test items constructed to favor 1 group over another was investigated on parameter estimates from 2 item response theory-based computer programs--BILOG and LOGIST--using data for 1,000 White and 1,000 Black college students. Use of prior distributions and marginal-maximum a posteriori estimation is…

Reports on a study of 257 London Train Operators who viewed a short Computer-based Training Module (CBT), completed a Cognitive Styles Analysis, and then performed related tasks. Multivariate analysis revealed the influence on learning performance of age, cognitive style, and attitude to technology. Includes tables, graphs, and statistical…

This research investigated whether computer anxiety is different if the measure is administered by computer rather than by paper and pencil. The study compared two groups of students (N=83) who were gathered from three undergraduate sections and one graduate section of a required computer class for in-service and pre-service teachers using anxiety…

A study was undertaken at Amarillo College (AC), in Texas, to evaluate the services offered by the college and generate data to provide a basis for personnel planning, the continuation of programs, and the development of new programs. Computerized surveys were developed to ensure increased efficiency in tabulating results and to standardize the…

A situation in which computer-assisted instruction was combined with teacher-taught classes and computerized diagnostic adaptive testing was examined. The computerized diagnostic adaptive test for pre-algebra signed-number lessons was programmed along with a computer-managed routing system by which examinees were sent to the instructional unit…

Investigates the validity and reliability of performance assessments using data from over 300 fifth and sixth graders. Results demonstrate the gap between the reality of measurement through performance assessments and the political rhetoric that would institute these assessments in a national examination system in the immediate future. (SLD)

To examine the impact of transitioning 4th grade reading comprehension assessments to the computer, 219 fourth graders were randomly assigned to take a one-hour reading comprehension assessment on paper, on a computer using scrolling text to navigate through passages, or on a computer using paging text to navigate through passages. This study…

The family of Weibull distributions was investigated as a model for the distributions of response times for items in computer-based criterion-referenced tests. The fit of these distributions were, with a few exceptions, good to excellent according to the Kolmogorov-Smirnov test. For a few relatively simple items, the two-parameter gamma…

This study explores the utility of analytic scoring for the TOEFL® Academic Speaking Test (TAST) in providing useful and reliable diagnostic information in three aspects of candidates' performance: delivery, language use, and topic development. G studies were used to investigate the dependability of the analytic scores, the distinctness of the…

The College Board Computerized Placement Tests are intended for use by two- and four-year colleges in determining whether entering students are prepared for college-level work in English, reading, and mathematics, or whether they need developmental studies. Seventeen colleges and universities participated in pilot testing of the College Board…

The sequential probability ratio test (SPRT), developed by Abraham Wald, is one statistical model available for making mastery decisions during computer-based criterion referenced tests. The predictive validity of the SPRT was empirically investigated with two different and relatively large item pools with heterogeneous item parameters. Graduate…

This preliminary study examines what the effects of additional time and different media have upon the overall quality of English language learner's written assessment tests. Sixteen intermediate-level students (L1 Cantonese), enrolled at a satellite campus of an American university within Asia, manually wrote a 45-minute timed placement test in…

The purpose of this study was to examine the impact that proctored versus un-proctored testing would have on learning for an on-line content module; and examine the relationship between LASSI variables and learning. A randomized, pre-test/post-test control group design was employed. College students in a pharmacy curriculum, were randomized to two…
