The application of technology in classroom settings has equipped educators with innovative tools and techniques for effective teaching practice. Integrating digital technologies at the elementary and secondary levels helps to enrich the students' learning experience and maximize competency in the areas of science, technology, engineering, and…

Presented is a simulation program for Apple II computer which assays the effects of a series of variables on bacterial growth and interactions between microbial populations. Results of evaluation of the program with students are summarized. (CW)

Discusses hardware and software used to teach scientific method, ecology, evolution, mitosis and meiosis, photosynthesis, cellular respiration, circulatory and respiratory systems, reproduction and drugs, behavior, and genetics. (MKR)

Explains a study that proposed and tested how graphical representations influence what is learned and recalled from text. Results highlighted the importance of graph-focusing strategies for text learning and support the creative use of interactive computer presentation. (ML)

Described is a computer program, AQUASIM, which simulates interaction between environmental factors, phytoplankton, zooplankton, and fish in an aquatic ecosystem. The conceptual flow, equations, variables, rate processes, and parameter manipulations are discussed. (CW)

Presents a method of calculating acceleration resulting from gravity using computer-controlled photogates. (ZWH)

Describes a way to use computers in teaching chemistry, in this case in a demonstration lesson on supercooling using a thermister in a game port to interface the computer with cooling phenyl salicylate. Discusses the advantages over the traditional method of instruction. (CW)

Resistance probes for the laboratory can be divided into two main categories: (1) those involving direct use of resistance; and (2) those involving an indirect use of resistance. Described are several applications of both types related to chemistry and physics. (RH)

Asynchronous computer-based conferencing offers several unique capabilities as a medium. Participants can read and write messages at whatever time is convenient for them, groups can interact even though participants are geographically separated, and messages are available to readers almost instantly. Because the medium has served for over a decade…

Described is the use of a spreadsheet to model dynamic phenomena using numerical iterative methods. Uses the discharge of a capacitor, simple and damped harmonic motion, and the flow of heat along a bar as examples. (Author/CW)

Examines 92 Canadian secondary school teachers for their familiarity with categories of educational computer applications. Reports relationship of variables such as teacher age, gender, subject area specialization, and teaching experience as they related to knowledge and use of computers. Lists 16 references. (YP)

Scientists need to measure and communicate, to handle information, and model ideas. In essence, they need to process information. Young scientists have the same needs. Computers have become a tremendously important addition to the processing of information through database use, graphing and modeling and also in the collection of information…

Reviews the use of spreadsheets and gives examples of how they can be adapted for data analysis in a science laboratory situation. Highlights the benefits and limitations of this approach for students. (ML)

Illustrates a method used to handle class size experimental data. Demonstrates this method using the SUPERCALC 3A spreadsheet program for an Apple II computer. Details an example of its use. Shows how to eliminate erroneous data. Gives examples of screens and graphical illustrations from the example experiment. (CW)
