Reviews three chemistry software programs at the high school and college general chemistry level for the Apple II family. Includes "Chemical Nomenclature and Balancing Equations,""Principles of Stoichiometry," and "Solubility." (MVL)

Describes a full day of chemistry fun and competition for high school chemistry students. Notes teams have five students from each high school. Lists five competitive events for each team: titration, qualitative analysis, balancing equations, general chemistry quiz, and quantitative analysis with atomic absorption spectroscopy. (MVL)

Describes a prototype for the use of local area network (LAN) technology in a sixth grade earth science curriculum. Classroom activities that focus on cooperative small group learning are discussed, coordinated investigations as a framework for scientific activities in the classroom are explained, and possible future work with LAN environments is…

Discussed are problems encountered when a gas absorption experiment with strong measurement error is used. Notes students either avoid the experiment or report it as defective. Provides ideas to make lab experiments more instructive. (MVL)

Describes research conducted on the organization of information from many disciplines to teach social issues raised by nuclear technology. States that the social sciences provided the organizational base for most courses examined, courses emphasized moral responsibility and political choice, and syllabi emphasized technological, strategic, and…

Reviews a monograph which addresses children's higher-order thinking skills. Suggests the following for teaching problem solving: identify and develop content-independent and content-dependent problem-solving skills, connect developed skills through workshop-style activities to subject discipline, and help students identify and reconstruct their…

Announces the development of a videodisc module which provides access to the U.S. Department of Agriculture information network. Relates sources of information, module description, recommendations for use, and software specifications. Describes the equipment needed. (RT)

Describes a course which has been designed to develop oral and written communication skills appropriate for engineering graduate students and for the demands of their post-graduate careers. Provides course strategy and content. (MVL)

Discusses two weather computer programs that allow users to see current weather maps and readings across the United States by modem hookup. Describes the features of "Weather Brief" and "Accu-Weather Forecaster" and includes the approximate daily phone cost of each. (MVL)

Describes the use of computer spreadsheet programs in physical chemistry classrooms. Stresses the application of bar graphs to fundamental quantum and statistical mechanics. Lists the advantages of the use of spreadsheets and gives examples of possible uses. (ML)

Describes a demonstration showing the chemical reversibility between the chromate and dichromate ions. Includes reaction equations and listing of equipment needed. Recommends a demonstration for illustrating Le Chatelier's principle and stoichiometric relationships. (ML)
