Discusses three trends in computer-oriented chemistry instruction: (1) availability of interfaces to integrate computers with experiments; (2) impact of the development of higher resolution graphics and greater memory capacity; and (3) role of videodisc technology on computer assisted instruction. Includes program listings for auto-titration and…

Outlines different ways to use microcomputers in science laboratories: (1) as electronic blackboards (simulations, data presentation, number crunching); (2) as universal laboratory instruments (control technology, sound output, time measurement, digital-analog conversions); (3) for educational management; and (4) for computer assisted learning.…

Adjunct questions were inserted after each of 12 computer-animated graphics sequences shown to 160 eighth-grade science students. These sequences presented two relationships in a purely spatial fashion. Four randomly assigned treatment groups received questions targeting one of the two relationships (temperature or molecular motion) over all or…

Presents a computer program which prints out a calendar corresponding to any year A.D. and states the objectives for such a program. Shows an example of a sample run. (RT)

A computer program, making use of interactive computer graphics, has been developed to help students become fluent in the mathematical procedures needed to understand concepts of addition of waves. Background theory, use of the program, and technical and educational features of the program (written in Fortran) are discussed. (Author/JN)

Discusses a microcomputer-based laboratory (MBL) study (n=75) which uses multiple temperature gathering devices (mercury thermometer, digital thermometer, and computer probe) and graphing methods (hand graphs, delayed computer graphs, and real-time graphs). Reports that MBL real-time graphing provides significant increases in graphing skills. (MVL)

Discusses chaotic behavior (movement) in a nonlinear system using LOGO programs. Presents several examples with program listings. (MVL)

Describes computer program (available on diskette for Apple IIe/II-plus, Commodore PET/CBM, or Commodore 64) providing drill/practice on concepts of electric charge, electric current, and electric potential difference. A second diskette provides a test of fifteen multiple-choice questions, with option to print score and areas of weakness. (JM)

Discusses under what conditions computer simulations should be used. Considers the aspects and qualities of computer simulations used in simulating science laboratory experiments. Provides suggestions for selecting or designing simulations. Examines the idea of transfer when using simulations. (MVL)

Identifies six computer-oriented approaches to teaching concepts in chemistry. Describes courseware and equipment involved in various experiments dealing with such topics as polymer configurations, stepper motors, conductometric titration, kinetic spectrophotometry, and overlap integrals. (TW)

This ERIC Digest presents a brief description of some applications and findings of the microcomputer in science classrooms. It is suggested that microcomputer simulations are at least as effective as hands-on experiences for some cognitive outcomes and may in fact enhance these outcomes when the simulations are sequenced to follow hands-on…
