This paper describes the use of Java to develop a variety of educational materials to supplement both traditional instruction and Internet-based instruction. Efforts have focused on three projects that vary in course level, content, and style of interaction. Unlike the simple Java applets on the Web, these are very sophisticated simulation…

The purpose of this study was to determine the procedural knowledge brought to, and created within, a pond ecology simulation by students. Environmental Decision Making (EDM) is an ecosystems modeling tool that allows users to pose their own problems and seek satisfying solutions. Of specific interest was the performance of biology majors who had…

Investigates the impact of computer simulation on students' academic achievement and their mastery of science process skills with regard to their cognitive stages. Based on the computer simulation program "The Growth Curve of Microorganisms" which requires 10th grade biology students to use problem solving skills while simultaneously…

Presents model of instructional strategy planning that links specific cognitive learning and thinking processes with specific computer-based instructional strategies. Topics discussed include memory systems; types of knowledge; drill and practice; tutorials; task-oriented simulations; problem-oriented simulations; and self directed experiences.…

Reports the results of a study that examined the patterns of interactions of high school student partners engaged in problem-solving activities while working through computer simulation activities in an astronomy lab. Observations, interviews with teachers and students, and a software program evaluation are discussed. (LRW)

A study investigated whether rotating three-dimensional objects using virtual reality would affect flexible thinking in 14 children (ages 8-11) with hearing impairments. Children played virtual 3-D Tetris individually, 15 minutes once weekly over 3 months. Before-and-after testing showed significantly improved flexible thinking in the experimental…

Two studies were conducted to determine the effects of gender, reasoning level, and inductive and deductive computer-simulated experiments (CSE) on problem-solving abilities in introductory general chemistry. In the pilot study, 254 subjects were randomly assigned to control (computer-assisted-instruction tutorials), inductive or deductive CSE…

This report characterizes human problem solving in digital circuit design. Protocols of 11 different designers with varying degrees of training were analyzed by identifying the designers' problem solving strategies and discussing activity patterns that differentiate the designers. These methods are proposed as a tentative basis for assessing…

As drill and practice programs in computer assisted instruction (CAI) in English give students a chance to test their understanding and free the teacher from test grading, they seem a legitimate if unexciting use of the computer; but what seems less defensible is that, according to some estimates, 90% of available CAI software is of this drill and…

For decades, every chemical engineer has been asked to have a background in separations. The required separations course can, however, be uninspiring and superficial because understanding many separation processes involves conventional graphical methods and commercial process simulators. We utilize simple, user-­friendly mathematical software,…

The effectiveness of environmental simulations in developing students' awareness of environmental issues, whether perception of environmental relationships was affected by the simulations, and whether the use of microcomputers as the medium of instruction affected student attitudes towards computers were investigated in this study. Undergraduates…

In the late 1960s and early 1970s a considerable amount of research was conducted on methods for authoring and structuring instructional materials by researchers who did not, at that time, have access to the existing delivery systems necessary to fully implement their ideas. One of these methodologies is Structural Communications, developed by…

The Educational Technology Center (ETC) Complex Systems Project was initiated to explore ways of using computers to help students understand systems which have often proven too complex for most high school students to understand. Preliminary work concentrated on the cognitive processes involved in modeling simple systems. This paper describes an…

Recent research on solving addition and subtraction word problems has resulted in the construction of theoretical models of children's problem-solving processes. Some of these models have been translated into computer programs. Characteristics and predictions of the theoretical analysis developed by Riley, Greeno, and Heller (1983) are discussed…

Promotes the use of computer modelling in physics instruction. Describes Dynamic Modelling System (DMS) and the procedures employed in applying it to problem solving in physics. Provides fundamental information on BASIC language and techniques for using DMS. (ML)
