Uses a traditional approach with problem solving, a concrete approach with manipulatives, and a visual approach with computer spreadsheets to teach the arithmetic mean to 22 children in grades 4-6 in three multiage groups. Differences among pretest, posttest, and interview performances suggest some advantage to the use of a visual instructional…

Discusses science educators' interest in Web-based learning (WBL). Provides a classification scheme by which scientifically-oriented educational websites can be evaluated for content level. Presents an example of site evaluation in the field of atomic structure and discusses the potential embedded in this taxonomy to assist the web site developer,…

Describes five existing classroom projects that use multimedia tools and computer technology to teach elementary and high school students multimedia authorship. Each project description discusses the type of computer software used and its uses to students. Projects teach students to incorporate video, audio, text, and graphics into…

Describes an introductory computing course in which first-year students registered their presence and submitted assignments by electronic mail. Returning assignments by e-mail was found to be an effective method of giving individual help to those needing it most; individual student misconceptions could be more easily detected; and class discipline…

Calling computers tools or "add-ons" overlooks their expanding capabilities and interactive possibilities. School computer systems should be viewed as structured learning environments with complex, comprehensive capabilities to access and manipulate information. Computer environments can support changes in educational structures,…

Comparison of the effectiveness of two computerized environments, Schemes for Problem Analysis (SPA) and Algebraic Proposer (AP), with two sixth-grade classes found that in solving easy word problems, both software systems were equally helpful, but in harder word problems, those students who learned with SPA experienced more success than those who…

Describes the use of manipulatives for solving simple combinatorial problems which can lead to the discovery of recurrence relations for permutations and combinations. Numerical evidence and visual imagery generated by a computer spreadsheet through modeling these relations can enable students to experience the ease and power of combinatorial…

Offers a description of cyberspace or the "Web" or "Net" and explains how to find information on it. (TB)

Lists helpful web sites for First Amendment research in an annotated format. (TB)

Navigates through a gopher site and then describes some common ways to use different mathematical gophers to obtain desired information. These skills include finding, reading, and downloading text-based files, searching a database, and downloading software. (AIM)

Describes the development, use, and evaluation of the "Osmosis Program" as a teaching tool to elicit and challenge college students' understanding about diffusion and osmosis. Results showed students using the program performed better on a diffusion and osmosis assessment test than students not using the program. (Author/MKR)

Describes the development of Casebook of Project Practices (CaPPs) to help teachers learn a constructivist approach to science teaching--project-based science. Presents a study using CaPPs in a teacher development institute. Implications concern backgrounds teachers bring to the use of multimedia and how these backgrounds influence how they use…

Presents strategies to enhance the use of technology by teacher education faculty. The strategies include the following: encourage creativity and peer coaching; support faculty in all ways; provide ongoing staff development; offer flexible technology choices; address faculty complaints; explain the relevance of educational technology; do not…

Reports a study with 27 adults, both native French-speakers and native English-speakers, on the effectiveness of using a spell-checker as the core element to teach French spelling. The method used authentic materials, individualized monitoring, screen and hard-copy text reading, and content sequencing based on errors. The approach generated…

The Baldufa project at the Polytechnic University of Catalonia (Spain) is designed to assist physics teachers and students with teaching and learning activities. It has established Web and electronic-mail servers, is creating physics-related documents to be shared, is elaborating teaching strategies for using stored information, and offers…
