This paper addresses the problem of probabilistic reasoning as it applies to Truth Maintenance Systems (TMS). A computer-based Belief Maintenance System (BMS) has been constructed which manages a current set of probabilistic beliefs in much the same way that a TMS manages a set of true/false beliefs. It may be thought of as a generalization of a…

Several studies were conducted in 1987 by the Multilevel Evaluation Systems Project, which focuses on developing a model for a multi-purpose, multi-user evaluation system to facilitate educational decision making and evaluation. The project model emphasizes on-going integrated assessment of individuals, classes, and programs using a variety of…

This document reports on the first year of the STACI (Systems Thinking and Curriculum Innovation) project, a two-year project which is examining the cognitive demands and consequences of using the STELLA (Structural Thinking Experimental Learning Laboratory with Animation) software to teach systems thinking, content knowledge, and problem solving.…

The Rasch Model and various extensions of this model can be formulated as a quasi loglinear model for the incomplete subgroup x score x item response 1 x ... x item response k contingency table. By comparing various loglinear models, specific deviations of the Rasch model can be tested. Parameter estimates can be computed using programs such as…

Geographers in the United States rely heavily on microcomputers. They employ microcomputers to enhance three general categories of tasks: word processing and other productivity needs, geographic instruction, and discipline-specific applications. Word processing and desktop publishing continue to be the primary uses of microcomputers by…

Developed to identify and qualitatively assess computer system evaluation techniques for use during acquisition of general purpose computer systems, this document presents several criteria for comparison and selection. An introduction discusses the automatic data processing (ADP) acquisition process and the need to plan for uncertainty through…

Describes the emphasis of decision support systems as being on the decision making process itself, rather than the flow of information; reviews the uses of microcomputers in libraries in recent years; and compares five decision modeling software packages. An appendix lists the name, manufacturer's address, price, and hardware requirements of each…

Routines developed for an ongoing course in research methods and statistics provides examples of the custom instructional applications that can be created using extended BASIC and a light pen, including title and transition displays, progressive disclosure, animation, overlays, and simulations. Strengths of this technique are reviewed. (MBR)

Using three new computer software programs in conjunction with role playing and class discussion, teachers introduce students to the stock market, Wall Street, economics, and business while simultaneously teaching computer applications. Each program and its classroom application are discussed; companies to contact are listed. (JL)

Describes the creation of the computer program "BOUNCE," designed to simulate a weighted piston coming into equilibrium with a cloud of bouncing balls. The model follows the ideal gas law. Utilizes the critical event technique to create the model. Discusses another program, "BOOM," which simulates a chain reaction. (CW)

Covariance structure modeling by LISREL was used in an analysis of relations between intellectual ability, as measured by the Finnish version of the Illinois Test of Psycholinguistic Abilities (ITPA), and achievement in reading, writing, foreign language, and mathematics in longitudinal data on 234 Finnish school children. The validity of the ITPA…

This article reviews five modes of computer-assisted software so that teachers will be more aware of them and use computers more in their classrooms. The five modes are the following: (1) drill and practice; (2) tutorial; (3) simulation; (4) demonstration; and (5) instructional games. Teachers should review softwares and choose those that meet…

This overview of computer uses in occupational training discusses three computer-based training modes--embedded, stand-alone, and adjunct training. An adjunct training system is described which captures task realism through a simulation to teach the use of a command and control system. A pilot study of this adjunct system's use is described.…

Describes use of computer simulation which generates bird songs so that students can analyze song motifs and sequences as an introduction to descriptive analysis of behavior in an animal behavior course. Advantages of the simulation are discussed together with computer hardware/software needed and data presentation, analysis, and generation…

Portrays development of a personal-computer laboratory for engineering majors at Washington Univertsity, St. Louis; reviews issues addressed by the lab including access, security, administration, and standardization of personal-computer configuration; and describes computer-based courses offered by the lab and computer software developed for…
