Advantages and disadvantages of standard Rasch analysis computer programs are discussed. The unconditional maximum likelihood algorithm allows all observations to participate equally in determining the measures and calibrations to be obtained quickly from a data set. On the advantage side, standard Rasch programs can be used immediately, are…

This essay summarizes the theory and practice of computer simulation, assesses the state of the art of simulation with respect to pedagogically relevant processes like learning, and speculates about the impact of such simulations on pedagogical research and practice. Arguing that the use of computer simulation as a technique for building formal…

Designed to investigate whether or not science teachers can positively influence student achievement in, and attitude toward, science, this study focused on a specific teaching strategy and utilization of a computer-based simulation. The software package used in the study was the simulation, Volcanoes, by Earthware Computer Services. The sample…

One of a series of developmental projects that have produced and evaluated applications of an advanced multimedia, computer-based technology for basic skills education for Army enlisted personnel, this project focused on the development of an integrated curriculum to teach learning strategies and problem-solving skills. The first task was to…

This paper reviews the basic elements of the EM approach to estimating item parameters and illustrates its use with one simulated and one real data set. In order to illustrate the use of the BILOG computer program, runs for 1-, 2-, and 3-parameter models are presented for the two sets of data. First is a set of responses from 1,000 persons to five…

In this paper the theory that human thinking proceeds according to the computer model, or symbol manipulation, is reviewed and challenged. The research used as subjects five highly rated tournament chess players who "thought aloud" during a chess game to provide tape recorded protocols of decisions made while playing. These protocols…

The central purpose of the present study was to evaluate several statistical techniques (analysis of variance (ANOVA) on raw gains, standardized ANOVA, standard analysis of covariance (ANCOVA), and z-score ANOVA) under various quasi-experimental conditions (three levels of reliability, three levels of sample size, three levels of gain, and the…

Three research efforts that used computer-based simulations for maintenance training were in progress when this report was written: Game-Based Learning, which investigated the use of computer-based games to train electronics diagnostic skills; Human Performance in Fault Diagnosis Tasks, which evaluated the use of context-free tasks to train…

Expert reasoning in the natural sciences appears to make extensive use of a relatively small number of general principles and reasoning strategies, each associated with a larger number of more specific inference patterns. Using a dual declarative hierarchy to represent strategic and factual knowledge, a framework for a robust scientific reasoning…

The 63 papers in this collection include two keynote addresses: "Patient Simulation Using Interactive Video: An Application" (Joseph V. Henderson), and "Intelligent Tutoring Systems: Practice Opportunities and Explanatory Models" (Alan Lesgold). The remaining papers are grouped under five topics: (1) Artificial Intelligence,…

This report reviews local tax reform and describes an approach to simulating the effects of proposed tax reform on local school districts in Pennsylvania. The microcomputer spreadsheet simulation led to the development of a model able to meet the feasibility criteria established for such a simulation model. The model was designed to input…

Flight simulators, computer-based instruction (including both computer-assisted and computer-managed instruction), and maintenance training simulators are as effective, when used for training, as aircraft, conventional classroom instruction, and actual equipment, respectively. Data from about 100 studies are reported to support this finding. These…

There are two major concerns about the teaching of high school biology. One is the degree to which students memorize laws, facts, and principles, and the second involves the role of the classroom teacher. These aspects result in a discrepancy between the theory and practice of science education. The purpose of this report is to provide: (1) a…

The Transparent Computer, a computer simulation designed to teach programming concepts to non-programmers, provides a graphic representation of the computer and illustrates information flow within the units of the computer. The emphasis of the simulation is on the acquisition and application of concepts and comprehension of the structuring of…

Designed to offer direction for classroom teachers and administrators in the development of an exploratory computer literacy program for grades 9-12, this resource unit comprises four major sections, four appendices, and two resource lists. The introductory section provides information on the history of Hawaii's computer literacy program; cites…
