We describe a recent project that explored combined use of Internet client-server technology and interactive computer modeling software for improving secondary science teaching. We envisioned a constructivist network in which teachers make contributions to the resources available. The purpose of the network was to promote the emerging field of computer modeling in high school science. Our approach coupled the networking and curricular initiatives with evaluation of changes in classroom core practices—those which have a traceable impact on student learning. Distribution of work, ideology of science, teaching styles, and curricular goals come together dynamically to influence teachers' use of modeling technology in the high school science classroom. A combination of Internet tools, each affording a different contribution to the spread of innovation, provides the best promise for future networks of this kind. 相似文献

We describe a recent project that explored the use of interactive computer software for teaching Einstein's special theory of relativity to secondary school studients. Our approach couples results from recent cognitive science research with modern techniques for using computers to help students visualize and experiment with otherwise inaccessible phenomena. One the products of this research is RelLab, a computer-based exploratory tool for constructing gedanken, or thought experiments involving physical systems in relative motion. We will describe our efforts in designing and testing this software for affecting change in students' concepts of space and time. Relativity is ideally suited for such a study because understanding it requires a radical reconceptualization of these quantities.Advanced Physics from an Elementary Viewpoint, NSF grant MDR-9016417. 相似文献
