Preschoolers 4 and 5 years of age were found to use four strategies differing in temporal characteristics as they solved simple addition problems with sums of 10 or less. Three strategies had visible and/or audible aspects, and one was covert, involving retrieval from memory. The harder the problem, the more often the children used an overt…

Two methods for solving problems are presented, designed to help people overcome difficulties that often occur in the problem-solving process. One difficulty people have is in using their knowledge to reach the decisive solution idea. The proposed "method of description" for eliminating this difficulty is based on a directed enrichment of the…

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…

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)

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)

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 the construction of a knowledge representation from the identification of the problem (nephrotic syndrome) to a running computer simulation of causal reasoning to provide a vertical slice of the construction of a cognitive model. Interactions between textbook knowledge, observations of human experts, and computational requirements are…

Analyzes how 20 groups of management specialists in charge of a computer-simulated company behaved when confronted with complex problems that arose. Difficulties stemmed from an incorrect use of available knowledge, a tendency to avoid risks and reduce uncertainty, and a motivational process which sheltered the subjective sense of competence. (AEF)

Defines instructional roles of dynamic visual displays (DVDs), including animation and interactive video, and provides guidelines for using them in media-based instruction. Topics addressed include theoretical bases; examples of strategic applications of DVDs; six instructional conditions for using DVDs; and considerations for the design and…

The teaching and learning potential of interactive video (IV) are explored. Some of the programs currently in use are described. The use of IV for simulations, practical work, problem solving, and presentational skills are discussed. (KR)

This article discusses 5 approaches that secondary researchers might use to obtain robust estimates in structural equation modeling analyses when using data that come from large survey programs. These survey programs usually collect data using complex sampling designs and estimates obtained from conventional analyses that ignore the dependencies…

For the thirty-seventh year, the Research and Theory Division and the Division of Instructional Design of the Association for Educational Communications and Technology (AECT) sponsored the publication of these Proceedings. Papers published in this volume were presented at the annual AECT Convention in Jacksonville, Florida. This year's Proceedings…

Complex decision-making environments often demand that a range of alternative strategies be identified and compared for their shared value in achieving desired ends. Simple parametric statistical procedures such as analysis of variance and discriminant function analysis can be used in such situations to compare (using selected criteria) the value…

Utah State University's intensive Spanish program uses video simulations of real-life experiences as the basis for classroom instruction in lieu of following a textbook, allowing the class to become student-centered, rather than instructor-centered, through a problem-solving group endeavor.

How the microcomputer can be used to reinforce basic statistical concepts and techniques is presented. The methods for achieving this include specific statistical problems, projects, games, and simulations for use with microcomputers. (MNS)
