Reviews two software packages: Graphical Analysis III and Lewis Diagrams. Finds Graphical Analysis III to be a fast and versatile graphing program for high school science classes with access to Apple II microcomputers. Lewis Diagrams is designed to aid in determining Lewis structures of molecules and ions for IBM computers. (MVL)

Describes two computer programs used to aid in data analysis: (1) Develops a method for the propagation of error involving the direct calculation of the error in the dependent variable using a spreadsheet; (2) Examines a simple numerical method for solving complex equilibria. Lists a FORTRAN 77 program. (MVL)

Describes a chemistry laboratory software package for interfacing the Apple IIe for high school and introductory college courses. Topics include: thermistor calibration, phase change, heat of reaction, freezing point depression, Beer's law, and color decay in crystal violet. Explains the computer interface and the tools needed. (MVL)

Argues that the changing informational content of biology, tightening cost constraints, improving electronic media, increasing pressures from advocates of animal rights, and the growing evidence of the effectiveness of electronic modes of instruction are undermining the traditional belief that all students in biology should have the benefit of…

Describes a case study of an advanced physics class that analyzes the implications of using computerized journalizing. Reports that this technique provides a vehicle for students and teachers to make their knowledge public, builds an atmosphere for valuing the conceptual understanding of others, and mediates an ongoing dialog between the…

Botany meets computer science in this activity, which challenges students to create a computerized seed catalog. Class members work together to develop a database of plants, much like the major seed companies do. (PR)

Discusses a study designed to understand 11th-grade students' learning during conversations with their teacher over and about a computer-based Newtonian microworld, Interactive Physics. Illustrates that students' learning was not local but persistent, in that they used appropriate canonical science talk without teacher support. (36 references)…

Spreadsheets are well suited to many geochemical calculations, especially those that are highly repetitive. Some of the kinds of problems that can be conveniently solved with spreadsheets include elemental abundance calculations, equilibrium abundances in nuclear decay chains, and isochron calculations. (Author/PR)

Described are four musical instruments constructed from polyvinyl chloride (PVC) pipe. The use of computerized synthesizers to play scales and chords is discussed. Suggestions for other illustrations of acoustics are included. (CW)

Modeling is important in science and in science education. Computer-based modeling opens up new possibilities for learning science, particularly now that appropriate software is available. This article describes high school students' use of Model Builder software in high school classrooms. (PR)

Investigates the conceptual-change process in grade 10 students during a computer-supported physics unit. Finds that many students vacillated between alternative and scientific conceptions from one context to another during instruction, and those few students who did exhibit context-independent and stable conceptual change appeared able to accept…

Discusses a project that was established to integrate computer technology, especially the Internet, into the science classroom. Argues for the importance of providing students with a program of study that exposes them to the widest possible range of ways of gathering information for problem solving. (Author/WRM)

Examines the relationship of microcomputer simulation graphics and alphanumeric modes of data presentation to ninth-grade biology students' science process skills and conceptual understanding of selected science topics (N=64). Concludes that use of microcomputers and appropriate software can result in significant learning and understanding of…

Introduces the Instructional Technology Project (ITP) which provides universal, 24 hours/7 days a week Internet access to both students and faculty and incorporates technology into the curriculum. Uses five different modules involving technology that include e-mail, electronic discussion board, CD-ROM and multimedia, internet browsers, and…

Reviews the use of interactive multimedia in teacher education. Explores design, development, and evaluation issues for four examples of multimedia learning environments in mathematics and science: the Student Learning Environment, Investigations in Teaching Geometry, Reflecting on Elementary Science, and the Project Support Environment.…
