Explains the hierarchic structure of the mammalian visual system. Proposes a model in which feedback pathways serve to modify sensory stimuli in ways that enhance and complete sensory input patterns. Investigates the functioning of the system through computer simulations. (ML)

Researched hypothesis-testing strategies (HTSs) used by counselors. Undergraduates and counselors-in-training interacted with a computer-simulated client counselor, then counselor. Of the three HTSs (confirmatory, disconfirmatory, and unbiased), the unbiased HTS was preferred choice of HTS, was stable across time and with different feedback, and…

Considers two basic models of the teaching-learning process, described as the didactic and the communication models, and applies them to computer assisted learning. Conventional and intelligent tutorials and simulation are used as examples to compare the amount of control students have over learning strategy, content manipulation, and domain…

Presents a computer-aided instruction model that uses the simulation of field battles to analyze the dynamic interrelationship of space and time in historical events. Implementation of the model is briefly discussed, and possible enhancements and applications for other areas are described. (Author/LRW)

Five papers on the use of computer simulation (CS) in educational research are presented. The impacts of CS on educational research, modeling task performance, use of CS in problem solving in subject-matter domains, an interpretation synthesis model of medical teaching rounds discourse for expert system interaction, and computer-based learning…

Described is a Monte-Carlo method for modeling physical systems with a computer. Also discussed are ways to incorporate Monte-Carlo simulation techniques for introductory science and mathematics teaching and also for enriching computer and simulation courses. (RH)

Use of a computerized simulation entitled "A Simulation of the First Year Teaching" by students in a teaching procedures class in physical education is described. (MT)

Uses examples from four exercises to show how computer-based education (CBE) is used to teach problem-solving in a physiology course. Screen prints are included to illustrate the exercises. Several benefits of using CBE strategies in physiology are also considered. (JN)

This study examined three statistical methods for selecting items for mastery tests: (1) pretest-posttest; (2) latent trait; and (3) agreement statistics. The correlation between the latent trait method and agreement statistics, proposed here as an alternative, was substantial. Results for the pretest-posttest method confirmed its reputed…

Presented are two problems that can be solved using a computer simulation by students who have completed Algebra II. The distance and bisector formulas and the various forms of the equations of a circle and straight line are the topics. Computer program listings are included. (MNS)

A microcomputer-based simulation, developed to promote preservice elementary school teachers' acquisition of fundamental feedback, time-management, and behavior-management skills through powerful reinforcement, prompting, and feedback training aids, was proven successful in several applications involving entry-level education students. (Author/CB)

Reliability and validity were examined for three computerized case management simulations in counseling, administered to experienced counselors, and three samples representing different levels of professional training and experience. Reliability coefficients were moderately high. Significant relations were found between performance on the…

Describes a laboratory exercise that introduces physics students to graphing. Presents the program format and sample output of a computer simulation of an experiment which tests the effects of sound intensity on the crawling speed of a snail. Provides students with practice in making exponential or logarithmic graphs. (ML)

The principle of the multiplier-accelerator interaction is explained, and how a computer program to model it can be developed is shown. A series of simulations that can be used to explore the model's behavior are suggested. The simulations can be used in college-level economics classes. (Author/RM)

Discusses the nature and development of computer software. Programing, programing languages, types of software (including dynamic spreadsheets), and software of the future are among the topics considered. (JN)
