Presents a computer interfaced experiment that relates the equations of force equals mass times acceleration and force equals the derivative of the pressure divided by the derivative of the time. Provides setup, sample data, and equations. (MVL)

Describes the software HyperCard for the Macintosh computer. Explains how it can be used as an information presenter and information expander. (PR)

Examines the effects of professional development in multimedia-based technology for 26 inservice and 14 preservice teachers on science and mathematics instruction. Focuses on three components critical to the success of this professional-development model: (1) linkage of pedagogy to technology; (2) collaborative teacher planning of instructional…

Offers free software for timing experiments, instructions for making a timing interface and a variety of switch sensors for any IBM-compatible computer, and suggestions for experiments. (AIM)

Many teachers have found that, no matter how enjoyable ecological studies are, students tend to dislike the computation of the large amounts of data gathered. Included is a description of an experiment that utilized time-saving features as well as the instructional and motivational benefits of using a computer spreadsheet program to analyze and…

Students in a grade 2-3, two-way bilingual classroom increased their understanding of scientific practice through a model-based methodology for science instruction. Students collaborated with peers and teachers to create computer models, construct physical models, and talk about their models in the classroom. Aspects of second language usage in…

Describes research within physical science courses for preservice elementary teachers, where groups of students had access to computers, examining how computers were used as representational tools to support meaning-making conversations within groups. Notes how special computer simulators facilitated student groups' construction of robust…

Discusses the impact of computer technology on education, highlighting concept maps, electronic learning logs, and computer simulations, which provide students deeper understanding of chemistry and research methods while doing real science and help teachers conduct ongoing formative assessment of class progress. Computer simulations help teachers…

Describes the evolution of the seven major physics syllabi used in all secondary schools in China and analyzes the shifts of these syllabi in terms of objectives, content, instructional hours and teaching methods. Suggests changes for China's future secondary-physics education, including the need for modern experimental equipment such as computers…

Describes a way of incorporating animations into spreadsheets using Excel software. (WRM)

Presents an online activity designed to teach middle- and upper-level elementary school students about the skeletal system. Students are given several questions about the human skeleton, then directed to several online science sites to find the answers. A student reproducible page is included. (SM)

To help students understand the connection that Earth and the solar system have with the cosmic cycles of stellar evolution, and to give students an appreciation of the beauty and elegance of celestial phenomena, the Chandra X-Ray Center (CXC) educational website contains a stellar evolution module that is available free to teachers. In this…

This paper reports design experiments on two Japanese elementary science lesson units in a sixth-grade classroom supported by computer support for collaborative learning (CSCL) technology as a collaborative reflection tool. We took different approaches in the experiments depending on their instructional goals. In the unit 'air and how things…
