Described is an activity in which a computer is used to acquire temperature and humidity data useful in investigating transpiration in plants. Materials and procedures are discussed and examples of results are presented. Factors which influence the rate of transpiration are discussed. (CW)

Presented is a computer simulation called "The Great Chemical Bead Game" which can be used to teach the concepts of equilibrium and kinetics to introductory chemistry students more clearly than through an experiment. Discussed are the rules of the game, the application of rate laws and graphical analysis. (CW)

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…

Background information, data input, data analysis, and advantages of using this method with this software are discussed. A flowchart of the event-trapping program structure and a printout of the program are included. (CW)

Investigates the many different desktop publishing packages available today. Lists the steps to desktop publishing. Suggests which package to use with specific hardware available. Compares several packages for IBM, Mac, and Apple II based systems. (MVL)

Provides explanations of 15 experiments, laboratory activities, demonstrations, and lessons for use in instruction. Includes information on Daphnia, wild garlic, crystals, gas chromatographs, bleaches, alcohols, reactivity series, chemistry formula, electronic keyboards and waveforms, interference and diffraction gravity, Moire fringe patterns,…

Discusses two computer problem solving programs: rule-based expert systems and decision analysis expert systems. Explores the application of expert systems to automated chemical analyses. Presents six factors to consider before using expert systems. (MVL)

Considers three questions regarding computer science courses: (1) Can performance be predicted?; (2) Does a solid mathematical background provide the student with an advantage?; and (3) Is gender a factor in performance or aptitude? Reports a strong math background was related to achievement in a beginning course while gender was not related. (MVL)

Examines current use of computers by historians and teachers of history. Attempts to predict extent of their use in next decade. Focuses on the use of four types of computer programs: word processors; spreadsheets and statistical packages; database management programs; and simulations. States that the computer is a tool historians can use to make…

Presents an overview of three ways that the computer can bridge the gap between reading and writing instruction: (1) word processing in the Language Experience Approach; (2) software to combine text and graphics; and (3) software to facilitate interactive reading and writing experiences. (MG)

Reviewed is the use of computer-assisted instruction in college science laboratories. Examples of computer interfacing are discussed. (CW)

Presents an overview of educational technologies available for use with special education students in rural areas, including teleconferencing, computers, electronic mail, and interactive videodisc. Examines benefits and weaknesses of telecommunications use for students, teachers, and administrators. (SV)

Presents an example using a computer to illustrate concepts graphically in an introductory course on differential equations. Discusses the algorithms of the computer program displaying the solutions to an equation and the inclination field of the equation. (YP)

Examines the effect of solar radiation on colored shingles. Describes the experimental procedure, results, and discussion. Presents a picture of the experimental arrangement and three graphs of data measured at different dates. (YP)
