xyZET: A Simulation Program for Physics Teaching

A simulation program, named xyZET, has been developed to support the teaching of physics and the preparation of interesting and challenging exercise material. xyZET offers a rich and complex user interface, which allows the development in 3D-space of numerous experiments in basic mechanics and electricity. It is also possible to visualize effects dependent upon relativistic changes of mass. In addition, the radiation of accelerated charge carriers can be demonstrated in accordance with the Linard Wiechert theory. A special learner mode has been implemented as an alternative to the normal working environment in which all the control elements are available to the user. In this learner mode, the program can be controlled by Java applets embedded in WEB pages. By clicking on active buttons, communication with the simulation program is established, using the TCP/IP protocol. This allows the learner to concentrate fully on the topic, and frees him or her from any control activity which might divert attention from the underlying science. Using xyZET and this external control feature a complete mechanics course has been developed, containing most of the traditional topics taught in 11th grade at German high schools (Gymnasium). The course material has been tested under classroom conditions and proven to be stable and effective. Further improvements can be expected if students have access to more powerful computers and more support and time is provided to allow exploratory and self-supported learning. xyZET was developed under UNIX and X-windows and runs on PC platforms under LINUX or Windows95/98.
