Illustrates different types of opportunities for using computer assisted instruction (CAI) on personal computers in the teaching of economics with four examples of currently available software. Describes the difficulties in providing and supporting CAI, and concludes with an analysis of the difficulties caused by the "public goods character" of…

Describes a variety of computer software. Subjects reviewed include history simulations and wordprocessing programs. Some of the eleven packages reviewed are Thog, North Utilities, HBJ Writer, Textra, Pro-cite, and Simulation Construction Kit. (BSR)

Describes the simulation of a nearest neighbor searching algorithm for document retrieval using a pool of microprocessors. Three techniques are described which allow parallel searching of a binary search tree as well as a PASCAL-based system, PASSIM, which can simulate these techniques. Fifty-six references are provided. (Author/LRW)

Learning about the physical environment from computer simulation models is discussed in terms of three stages: exploration, experimentation, and calibration. Discusses the effective use of models and presents two computer simulations written in BBC BASIC, STORFLO (for catchment hydrology) and SLOPEK (for hillslope evolution). (Author/GEA)

Reviews the uses of DEMOS, a set of demographic computer simulations which can be used to improve instruction in introductory sociology courses. Gives examples of both interactive and noninteractive exercises, concluding that DEMOS is easy to use and enjoyable, with approximately 90 percent of students recommending its continued use. (GEA)

Expert systems are computerized databases that can diagnose and recommend treatment for persons who are ill. The database contains information on more than 7,600 diseases generated from exhaustive questioning of experts. These systems supplement human expertise but do not replace the good teaching of physicians. (VM)

Discusses a program in Belgium which studied the use of computers as teaching devices for economics and business education in secondary schools. Describes three courses in which the computer is used as a source of information, as a tool for computer assisted instruction, and as a tool for simulation. (GEA)

The use of the arc-sine transformation in analysis of variance can lead to difficult inference situations and pose problems in interpretation. It can also produce tests of noticeably lower power when the null hypothesis is false, and is not recommended as a standard tool. Simulated illustrations are provided. (Author/GDC)

Discusses advantages and disadvantages of using computer simulations (including those involving application of mathematical models) in teaching physiology and pharmacology, indicating that the major benefit is in performing experiments that cannot be performed in the laboratory. Also considers a simulation on the interaction of drugs with…

Computer sampling from a multivariate normal spherical population was used to evaluate the type one error rates for a test of sphericity based on the distribution of the determinant of the sample correlation matrix. (Author/LMO)

A simulation model of episodic memory, MINERVA Z, is applied to the learning of concepts, as represented by the schema-abstraction task. The model successfully predicts basic findings from the scheme-abstraction literature, including some that have been cited as evidence against exemplary theories of concepts. (Author/LMO)

A model of information processing has been developed that combines concepts from the study of attention and the study of problem solving. The model has been realized as a computer program and used to simulate a variety of phenomena from the attention and performance literature. (Author/LMO)

This article presents an interview with Robert Taylor, a leading figure in educational computing. Among the topics covered are: (1) current developments in educational computing, (2) the changing role of teachers, (3) the resources computer technology will provide to social studies teachers, and (4) whether the probable future uses of computers…

This article provides a diverse collection of examples of computer use in elementary and secondary school social studies. Names and addresses are provided for contacting many of the projects. (JDH)

Examines the extent to which a process control computer system is assisting departmental research (by providing a comprehensive and flexible data logging and plant control system) and providing a teaching facility for the department by live demonstrations of plant monitoring and control applications, simulation, and student implementation of…
