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)

Technology can be useful in physics classrooms, though teachers must be careful not to let technology remove students from first-hand experiences with nature through observation and experimentation. The paper examines how to enhance physics instruction using computers as graphing tools, for data collection, and as real-world simulators. (SM)

Discusses the use of intelligent tutoring systems as opposed to traditional on-the-job training for training operators of complex dynamic systems and describes the computer architecture for a system for operators of a NASA (National Aeronautics and Space Administration) satellite control system. An experimental evaluation with college students is…

Two methods of assessing student learning of a hands-on instructional unit are compared. One method involves manipulation of concrete materials, and the other method involves manipulation of icons on a computer to solve an electric circuits problem. Sixth-grade students in an inquiry-based science program completed both assignments. (LZ)

Presents results of a 1991 national survey conducted in The Netherlands that investigated the use of computer-assisted learning (CAL) in higher education. Topics addressed include academic disciplines using CAL; types of CAL, including drills, tutorials, and simulations; level of learner control; authoring languages and programing languages; and…

Describes a project that uses a computer and a dot matrix printer to simulate the holographic recording process of simple object structures. The process' four steps are (1) superposition of waves; (2) representing the superposition of a plane reference wave on the monitor screen; (3) photographic reduction of the images; and (4) reconstruction of…

Utilizes a quasiexperimental design to examine the impact of microcomputer simulations on environmental problem solving by community college students. The experimental group of students (n=34) showed a highly significant improvement in problem-solving skills after being exposed to three simulation models that focused on lake pollution analysis,…

Discusses virtual reality (VR) technology and its possible uses in military training, medical education, industrial design and development, the media industry, and education. Three primary applications of VR in the learning process--visualization, simulation, and construction of virtual worlds--are described, and pedagogical and moral issues are…

Information on student learning in terms of amount and efficiency when using interactive video instead of traditional laboratory methods as well as questions on the use of live animals for instruction is provided. The methods, results, discussion, and summary are included. (KR)

Considered are several mathematical models that can be used to study different waiting situations. Problems involving waiting at a red light, bank, restaurant, and supermarket are discussed. A computer program which may be used with these problems is provided. (CW)

This study of 40 undergraduates examined whether aiding as cognitive support (i.e., offering computer users knowledge they are missing) can supplement lack of knowledge and capacity under tasks with high mental loading, such as dealing with irregularities in process control. Users of a railway traffic control simulator dealt better and faster with…

Describes changes in scientific research methods that have been brought about by the use of computers. Presents an example of the falling of a body in a fluid to show students how computers can be used to experiment with mathematical models and to automate experiments. Contains 11 references. (Author/WRM)

Two evaluations of video programs that involved groups of learners interacting with LaserVision software are presented. One concerns counselling skills for student teachers. The other is a geography simulation program. Program structure, group interaction, and the role of the instructor are discussed. Learners in both studies found the visual…

Describes the objectives and format of a course developed at the University of British Columbia (Canada) that was designed to introduce information technology to preservice science teachers. Sample student microcomputer-based laboratory projects are described that include computer simulations, multimedia presentations, and videodiscs; and…
