Electronic troubleshooting expertise was explored in the three contexts (design, production, and repair) that reflect distinct problem solving task environments. The purpose of the effort was to provide a more precise definition of the boundaries of expertise in electronics troubleshooting and the relationship of context to the development of…

To explore the potential of computer controlled videodiscs for simulating undergraduate science laboratory instruction, the Annenberg/CPB (Corporation for Public Broadcasting) Project funded the University of Nebraska to create and field test six videodisc laboratory experiments, two each in biology, chemistry, and physics. The six discs were…

Research was undertaken to investigate various methods of presentation of a computer based science simulation as it related to student content knowledge of the simulation concepts. Three treatment groups of sixth grade students were used in the study: (1) two students per computer interacting with the simulation; (2) a total class presentation of…

Designed to focus on student learning and to illustrate techniques that might be used with computers to facilitate that process, this paper discusses five types of computer use in educational settings: (1) learning ABOUT computers; (2) learning WITH computers; (3) learning FROM computers; (4) learning ABOUT THINKING with computers; and (5)…

Describes an approach to teaching population genetics and evolution and some of the ways models can be used to enhance understanding of the processes being studied. Discusses the instructional plan, and the use of models including utility programs and analysis with models. Provided are a basic program and sample program outputs. (CW)

Describes a microcomputer program that simulates the pattern of evolution and produces clade diagrams and summary statistics. Allows users to vary the odds affecting the fate of a species. (TW)

Reports on a study which was designed to determine if computer assisted instruction (CAI) can be used effectively in biochemical education. Results indicate that CAI in the drill and practice mode and computer simulations had no detrimental effect on the students' academic achievement and the students would like more CAI. (TW)

Reviews two studies whose results indicate that students who share computers develop better work skills and social attitudes. One study, using eighth graders and a computer simulation, measured performance on worksheets and final exams. The second study used language learning via computer-assisted instruction to compare results on achievement…

Discusses the Civil Servant Module, a new component of Global Systems Simulation, a comprehensive person-computer model for investigating international affairs. Its telecommunication capability, logistics, functions, spatial flexibility, and advantages are described and its implications for applying Global Systems Simulation as a research and…

Describes the development of a collaborative Internet-based simulation game for learning to solve knowledge management problems. The game builds on two starting points: on psychological and pedagogical developments in learning and instruction, and on a perceived need for better training of people working in the emerging field of knowledge…

Offers several LOGO programs to study the behavior of simple nonlinear systems. Suggests that LOGO is an excellent tool for studying chaotic systems. Offers suggestions for different forms of LOGO. Builds upon programs presented in a previous article. (MVL)

"Spreadsheets in Physical Chemistry" contains reviewed and classroom tested Lotus 1-2-3 and SuperCalc IV templates and handouts designed for use in physical chemistry courses. The 21 templates keyed to Atkins' physical chemistry textbook, the 7 numerical methods templates, and the 10 simulation templates are discussed. (MVL)

Describes a chemistry software program that emulates a modern binary gradient HPLC system with reversed phase column behavior. Allows for solvent selection, adjustment of gradient program, column selection, detectory selection, handling of computer sample data, and sample preparation. (MVL)

Discusses ways to generate and present images to students to study chemicals and chemical reactions. Contrasts current technologies with traditional means of displaying images. Summarizes experiences with the use of interactive videodisk-based lessons for chemistry instruction. (MVL)

Presents reviews by classroom teachers of software for teaching science. Includes material on the work of geologists, genetics, earth science, classification of living things, astronomy, endangered species, skeleton, drugs, and heartbeat. Provides information on availability and equipment needed. (RT)
