This study examined how four commonly used test equating procedures (linear, equipercentile, Rasch Model, and three-parameter) would respond to situations in which the properties or the two tests being equated were different. Data for two tests plus an external anchor test were generated from a three parameter model in which mean test differences…

The Systems Thinking and Curriculum Innovation (STACI) project is a multi-year research effort intended to examine the cognitive demands and consequences of learning from a systems thinking approach to instruction and from using simulation-modeling software. This study tests the potentials and effects of integrating the systems approach into…

Recent theoretical developments in cognitive psychology imply both a need and a possibility for methodological development. In particular, the theory of problem solving proposed by Allen Newell and Herbert A. Simon (1972) provides the rationale for a new empirical method for the processing of think-aloud protocols--trace analysis. A detailed…

Some diverse fields in which the effects of mental representations have been noticed are first discussed, largely through illustrations of differing problem-solving experiences. Then the LAKOS Project (Logical Analysis of Cognitive Organizational Structures) at the University of Osnabruck is described. A central concern is the specification of a…

The results of computer simulations of each of 17 variations on 4 prototypical desegregation plans applied to the Los Angeles Unified School District (LAUSD) are reported in this document. The prototypes, each representing a category of proposals offered at one point or another during the litigation of the desegregation issues are: (1) an…

This document reports the results of computer simulations of each of 19 variations on 4 prototypical desegregation plans applied to the Los Angeles Unified School District (LAUSD). Each prototype represents one of the following categories of proposals offered during the litigation of the desegregation issue in the California courts: (1) an…

During distributed virtual laboratory experiment sessions, a major problem is to be able to collect, store, manage and share heterogeneous data (intermediate results, analysis, annotations, etc) manipulated simultaneously by geographically distributed teammates composing a virtual team. The electronic notebook is a possible response to this…

Discusses computer-presented social situations (CPSS), i.e., microcomputer-based simulations developed to provide a new methodological tool for social scientists interested in the study of social relations. Two CPSSs are described: DaySim, used to help identify types of parenting; and DateSim, used to study interpersonal attraction. (21…

Standard maximum likeliheed estimation was compared using two forms of robust estimation, BIWEIGHT (based on Tukey's Biweight) and AMTJACK (AMT-Robustified Jackknife), and Rasch model person analysis. The two procedures recovered the generating parameters, but Rasch person analysis also helped to identify the nature of a response disturbance. (GDC)

Research on intelligent tutoring systems is discussed from the point of view of providing moment-by-moment adaptation of content and form of instruction to the changing cognitive needs of individual learners. Implications of this goal for cognitive diagnosis, subject matter analysis, teaching tactics, and teaching strategies are analyzed. (Author)

Describes the field evaluation process used to assess the validity, effectiveness, and efficiency of an interactive microcomputer simulation program designed for teachers and student teachers preparing to work with emotionally or behaviorally handicapped elementary school-age children. Results indicate the simulation was judged to be useful. (MBR)

Reports results of studies with an unsupervised learning paradigm called competitive learning which is examined using computer simulation and formal analysis. When competitive learning is applied to parallel networks of neuron-like elements, many potentially useful learning tasks can be accomplished. (Author)

Alternatives to traditional, large-class lecturing are discussed. They include using canned lectures, demonstrations and lecture experiments, computer simulations, problem-solving strategies, breaks during lectures, and movies. Moving out of large classrooms to laboratories and resource rooms (or giving an examination) is also suggested. (JN)

Describes RESTSIM, an interactive computer simulation program for graduate and upper-level undergraduate management, marketing, and retailing courses, which introduces naive users to simulation as a decision support technique, and provides a vehicle for studying various statistical procedures for evaluating simulation output. (MBR)

A computer simulation was developed to estimate the number of medical residents one or two faculty teachers could supervise in a university-based primary medical care teaching clinic. With no non-teaching tasks, it was shown that two teachers could supervise 11 residents, while one teacher was able to supervise only three residents under similar…
