Topics discussed include: (1) what is a simulation; (2) why simulate; (3) when to use simulations; (4) planning for instruction; (5) cautions and limitations; and (6) future developments. Suggests that computer simulation in science is both entertaining and motivating. (MP)

Presented are three computer projects: vector analysis, electric field intensities at various distances, and the Biot-Savart law. Programing suggestions and project results are provided. One month is suggested for each project. (MVL)

Provides a program listing in True BASIC which constructs several kinds of matrices: (1) matrices with integral entries that have inverses that have integral entries; (2) matrices with integral entries that have inverses that are rational numbers with reasonable denominators; and (3) matrices with integral entries and prescribed integer…

Examines if a self-paced, interactive microcomputer delivery system can decrease the time needed and improve the level of mastery as compared with a traditional self-paced instructional approach. Uses high school physics students with five activities and reports that no differences were found. (MVL)

Presented are some current facts about symbol manipulators and their relation to high school mathematics. The development of computer algebra systems is discussed. Five areas of computer algebra needing investigation (skill proficiency, understanding, curriculum content, student homework, and equity) are identified. (MVL)

Compares the computer assisted instruction (CAI) tutorial with its non-computerized pedagogical roots: the Socratic Dialog with Skinner's Programmed Instruction. Tests the effectiveness of a CAI tutorial on diffusion and osmosis against four other interactive and non-interactive instructional strategies. Notes computer based strategies were…

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 dimensionality in Euclidean geometry. Presents methods to produce fractals using LOGO. Uses the idea of self-similarity. Included are program listings and suggested extension activities. (MVL)

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

Reviews the Apple II program "Area and Volume" which investigates the areas and volumes of polygonal regions, circles, and solids for grades 6-12. Provides information updates on three programs: True BASIC 2.0, Turbo BASIC 1.0, and Microsoft QuickBASIC 3.0. (MVL)

Considers the development of a computer program for interactive, screen-oriented problem solving. Provides theoretical background and program development to determine internal energy, heat capacity, and entropy. Lists the program written in BASIC for Apple II computers. (MVL)

Uses a LOGO program and probability to solve systems of equations. Provides a physical model and a LOGO model. Lists programs and explains the methodology used. (MVL)

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)

Provides a software program for determining PI to the 15th place after the decimal. Explores the history of determining the value of PI from Archimedes to present computer methods. Investigates Wallis's, Liebniz's, and Buffon's methods. Written for Tandy GW-BASIC (IBM compatible) with 384K. Suggestions for Apple II's are given. (MVL)

Described are successful science activities which have been conducted on an international telecommunications network which links schools in the United States, Mexico, Japan, and Israel. Examined are several activities currently being developed. Reports an innovative way to involve a wide range of students in the scientific process. (MVL)
