This article introduces a special issue on technology-based assessment within special education. It notes the effects of the 1988 Technology-Related Assistance for Individuals with Disabilities Act and briefly reviews the nine papers in the issue. (DB)

A model integrating latent trait and latent class theories in characterizing individual performance on the basis of qualitative understanding is presented. This HYBRID model is illustrated through experiments with 119 Air Force technicians taking a paper-and-pencil test and 136 Air Force technicians taking a computerized test. (SLD)

Incidents affecting the implementation of large-scale testing programs are described to illustrate associated problems. Issues addressed include creation of test materials, preparation of answer documents, transportation of test materials, scoring and analysis of tests, and dissemination and utilization of test results.

Six medical school faculty evaluated the overall performance of eight students completing a surgery clerkship at the Michigan State University College of Human Medicine. Students were also evaluated by the National Board of Medical Examiners' Computer Based Examination (CBX). Faculty ratings correlated highly with scores produced by the CBX's…

Computer simulations were run to measure the relationship between testlet validity and factors of item pool size and testlet length for both adaptive and linearly constructed testlets. Making a testlet adaptive yields only modest increases in aggregate validity because of the peakedness of the typical proficiency distribution. (Author/SLD)

Reviews the potential of word processors for changing the ways in which students process written text and think about writing. Three levels of computer-aided writing are considered: simple word processors; computer-aided writing programs; and higher-level computer-aided processing; and improvements in writing quality.

Using one simulated and two real data sets, the effects of the systematic variation of the item-selection procedure and the stepsize method on the operating characteristics of computerized adaptive testing (CAT) for instruments with polychotomously scored rating scale items were studied. The six rating scale CAT procedures used performed well.…

Implemented computerized adaptive testing (CAT) to measure students' attitudes toward alcohol. Administered a paper-and-pencil version and a CAT version of an attitudes toward alcohol scale to 113 undergraduates enrolled in health education classes. Findings showed a high correlation between scores from the CAT and the paper-and-pencil versions.…

Exploratory and confirmatory factor analyses were used to explore relationships among existing item types and three new computer-administered item types for the analytical scale of the Graduate Record Examination General Test. Results with 349 students indicate constructs the item types are measuring. (SLD)

Compares the effectiveness of textual feedback to video feedback during two computer-assisted biology lessons administered to secondary students. Lessons consisted of a brief text introduction followed by multiple-choice questions with text or video feedback. Findings indicated that video feedback resulted in superior learning and comprehension,…

The effect that mode of administration, computer versus paper and pencil, had on the performance of 120 middle school students on multiple choice and written test questions was studied. Results show that, for students accustomed to writing on computers, responses written on the computer were more successful. Implications for testing are discussed.…

Compared easy and difficult versions of self-adapted tests (SAT) and computerized adapted tests. No significant differences were found among the tests for estimated ability or posttest state anxiety in studies with 187 Spanish high school students, although other significant differences were found. Discusses implications for interpreting test…

Reports findings of a two-year study of undergraduates at a United Kingdom university concerning the development and implementation of a general-purpose computer-based assessment (CBA) system. Results of questionnaires, observations, interviews, and a comparative analysis of student scores in conventional examinations and computer-based…

Investigates two problems: (1) do learning effects accrue in accuracy or response time when computerized tests are administered in two sessions? and (2) what are the effects of tonal pattern order and contour types on average item difficulty and length of response time for children with different levels of achievement?

This article shares how four students with severe disabilities in one Kentucky classroom achieved a "distinguished" rating, the highest rating, on their alternate portfolios by using the IntelliKeys keyboard as an alternative computer input device for the production of the alternate portfolio. It discusses tips for customizing IntelliKeys…
