The HyperCard-based computer-assisted instructional environment described--called the Virtual Computer (VC)--uses simulation to help learners acquire basic concepts about the functioning of computers. Discussion of the instructional design of the program includes Elaboration Theory, four learning phases, use of metaphors and analogies, other…

An exemplar-based model of social judgment is presented in which specific past experiences and more abstract schematic knowledge influence judgments and perceptions of people and groups. Computer simulations illustrate the way the model accounts for social influences on exemplar access and use and on the content of social judgments. (SLD)

Describes a set of six instructional simulation games in economics. Identifies simulation goals as increasing students' understanding of economic variables and political policy issues and enabling students to question, express views, and hold decision makers accountable. Suggests that by increasing economic awareness, the games will promote the…

A model-based modification of the standardization index based on a multidimensional item response theory bias modeling approach is presented that detects and estimates differential item functioning (DIF) (item bias) simultaneously for several items as well as differential test functioning (DTF). This SIBTEST procedure is tested through a computer…

Research has shown that learning is most effective when job-related. The ideal solution for many young students would be work-study programs or apprenticeships that closely relate learning and experience. Industry stresses the need for a fourth "R" beyond the basic literacy skills--readiness for change. Computer simulation programs may help enrich…

Discusses the use of educational technology for science and math instruction in elementary and secondary schools through conversations with six curriculum specialists and administrators. Highlights include the use of IBM and Macintosh hardware and software; hand-held computers; integrated learning systems; math workstations; computer simulations;…

Some commercially available software tools that have potential applications in the analytical chemistry curriculum are surveyed and evaluated. Tools for instruction, analysis and research, and courseware development are described. A list of the software packages, the compatible hardware, and the vendor's address is included. (KR)

Ignorance of the characteristics of a mixed population may lead to bias in a summary measure of a phenomenon. A test based on sample kurtosis is demonstrated by a simulation study to be more powerful than six other known tests in detecting a class of mixed normal distributions. (SLD)

Combining Rasch and latent class models is presented as a way to overcome deficiencies and retain the positive features of both. An estimation algorithm is outlined, providing conditional maximum likelihood estimates of item parameters for each class. The model is illustrated with simulated data and real data (n=869 adults). (SLD)

Contends that microcomputers were introduced into the social studies classrooms to teach higher order thinking skills. Maintains that computers can aid in teaching both process and content. Reviews new computer software programs and points out each programs' educational objectives and problems. Contends microcomputers are an invaluable tool of…

This study examined the application of the marginal maximum likelihood-EM algorithm to the parameter estimation problems of the normal ogive and logistic polytomous response models for Likert-type items. A rating scale model, based on F. Samejima's (1969) graded response model, was developed. (TJH)

Two issues in analysis of interactions in complex linear models are considered. One is the omnibus test for interaction, and the other concerns follow-up tests when the omnibus test is significant. Reconsidered omnibus and follow-up tests are illustrated on an educational data set analyzed using the Statistical Analysis System. (SLD)

Describes work at the National University of Singapore on the Internet in expanding a simulation game used in supporting a course in decision technology. Topics include decision support systems, multilingual support for cross-cultural decision studies, process support in a World Wide Web-enhanced multiuser domain (MUD) learning environment, and…

Investigates the effects of implementing individual and small-group learning structures with a computer simulation in college accounting. Results indicate students working alone expressed significantly more continuing motivation for their learning structure than did partnered students; students using extensive small-group structure exhibited…

Studies the use of a computer-assisted learning simulation episode during a unit on the growth curve of microorganisms in grade ten. Finds no significant gender differences in either the experimental or control groups. Contains 25 references. (DDR)
