Describes a problem-solving activity integrating a laboratory investigation with a database activity using Appleworks. Presents typical displays of the databases. The objective of the laboratory was to determine the identity of a pure substance by measuring physical properties and searching the database. (Author/YP)

Presented is a science activity designed to help students monitor the pH of rainfall. Materials, procedures and follow-up activities are listed. A list of domestic and foreign sources of information is provided. Topics which relate to acid precipitation are outlined. (CW)

Examined student behaviors during laboratory activities and the amount of time involved in each behavior. Approximately 89 percent of the student time was spent interacting with others. The amount of time spent on various activities appeared to be dependent on the nature of the activity and on the make up of the laboratory group. (YP)

Presented is a review of a computer learning package "Lab Partner & Lab Master" for Apple II computers. Hardware requirements, components, functions, costs, and student reactions are discussed. Graphic analysis capabilities are stressed. (CW)

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)

Reviews five Apple II computer programs: (1) The Research Companion: Supreme Court Decisions, grades 9-12; (2) Rebus Writer--vocabulary, problem solving, wordplay, grades 3-12; (3) Playing with Science: Temperature--MBL for grades K-7; (4) Exploring Science: Temperature--MBL for grades 6-12; and (5) ShowOff--graphics, desktop presentations for…

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)

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 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)

In the mid-1980s, data were collected on international science achievement as part of the Second International Association for the Evaluation of Educational Achievement Science Study. The seven articles of this collection report on various facets of the practical skills testing of this study in which six countries participated. (SLD)

Describes a mobile computer lab set up in a converted bus that is used by fourth graders as part of the math curriculum. The program, which emphasizes problem solving and spatial visualization, also addresses gender differences and in-service teacher training. The physical arrangements, including provisions for computer security, are described.…

Reports on a naturalistic study conducted with 24 low-achieving high school biology students that determined how the teacher and students used two computer-based videodisk programs, a print-based activity, and a dissection laboratory to learn about frog anatomy and to conduct a frog dissection. Future research is suggested. (Contains 14…

This second in a series of articles on planning for instructional computer networks focuses on site preparation, installation, service, and support. Highlights include an implementation schedule; classroom and computer lab layouts; electrical power needs; workstations; network cable; telephones; furniture; climate control; and security. (LRW)

This study documented the teaching practices of 2 exemplary biology teachers of grades 11 and 12 by means of an interpretive research methodology. Teaching practices are identified that may be considered exemplary and worthy of attention and analysis by other science teachers and science teacher educators. (PR)

The development of scientific explorations in schools and a framework for their assessment within the context of Britain's Graded Assessment in Science Project (GASP) scheme is described. The criteria for assessing the planning, implementing, concluding, and evaluating of explorations are provided. (KR)
