A theoretical integration of the storage and processing functions of working memory in language comprehension is presented. A computational theory is described in which storage and processing are fueled by activation. Capacity is expressed as the maximum amount of activation available in working memory for either storage or processing. (SLD)

Discusses methods of browsing in online public access catalogs (OPACs) and describes one method that uses information pertaining to the physical description of books from MARC records to simulate images of books on a library shelf. Electronic browsing through MARC is discussed, and methods of enhancing OPACs are reviewed. (51 references) (LRW)

Discussion of instructional transaction theory focuses on knowledge representation in an automated instructional design expert system. A knowledge structure called PEA-Net (processes, entities, and activities) is explained; the refrigeration process is used as an example; text resources and graphic resources are described; and simulations are…

The methodology of P. E. Holland and P. R. Rosenbaum (1986) to assess unidimensionality of binary data is outlined and illustrated through a simulation with 36 items for 2,000 examinees. How to interpret the results is discussed. (SLD)

Defines transposition operations (changing the way the display of the model proceeds) in diagrams within computer graphics. Describes transpositions that are spatial (moving the point of view or the point viewed), procedural (changing the flow of time), or organizational (arranging multiple simultaneous views and interjecting auxiliary measuring…

Discusses the use of behavioral simulations to study the processes that underlie strategy formulation and implementation. Seven behavioral simulations that attempt to mirror top management interactions in an organization are described and compared; research measures used are discussed; and implications for studies of strategic processes are…

A simulation study compared the performance of the Mann-Whitney "U" test, Student's "t" test, and the alternate (separate variance) "t" test for two mutually independent random samples from normal distributions, with both one-tailed and two-tailed alternatives. Type I error probabilities were computed with equal and…

Computerized Clinical Simulation Testing is an uncued, dynamic, interactive test that permits examinees to simulate the clinical decision-making skills used in the nursing management of client needs. It has the potential for helping boards of nursing to make more valid assessments about who is competent to practice nursing. (JOW)

Studied the one-parameter Item Response Theory model with normal item-characteristic curves in a longitudinal context. Results of a simulation suggest that the proposed procedure is rather robust against departures from normality. However, the estimation of the correlations between regression parameters can be seriously biased. (SLD)

Proposes a model for constrained computerized adaptive testing in which the information in the test at the trait level (theta) estimate is maximized subject to the number of possible constraints on the content of the test. Test assembly relies on a linear-programming approach. Illustrates the approach through simulation with items from the Law…

When business students created a learning organization in the classroom, they experienced group process issues, the need to deal with setbacks and manage change, and personal growth and development. In the process they developed organizational and management knowledge and skills. (SK)

Evaluated the effectiveness of gaming to create an interactive, stimulating learning environment as a review format for the Dental Hygiene National Board examination. Students (n=28) participated in either the gaming or a lecture review format. The gaming group scored higher on the exam on eight of 12 topics as well as on the case-based learning…

Describes the use of video simulation for teachers' self-assessment of their training needs in five teaching skill areas. Explains the diagnostic/prescriptive training model for teacher professional development; simulation-based assessment, including feedback reports; and developing a teacher professional development program. (LRW)

Suggests the use of written debriefing, in addition to oral debriefing, to improve learning through simulations. Discusses journal writing; the written concept technique; letters; written answers; guidelines for writing; and the evaluation of written debriefing. (LRW)

Illustrates the potential of simulation techniques for the teaching of German as a foreign language at the beginner's level. Reviews arguments for the use of simulations in language teaching, suggests a step-by-step procedure for using simulations, and presents a set of ready-to-apply simulation scripts on the topic of eating and drinking in a…
