Computer software packages that are commercially available for physics instruction are compiled in this paper. Information for each program includes: the broad subject category (i.e., mechanics, waves and sound, heat and thermodynamics, electricity and magnetism, optics and light, modern physics, mathematical models, or general reference/testing material); level of instruction; computer compatability; intended purpose (e.g. demonstration, simulation, data handling, remedial, exercises); and citations concerning where, if at all, the software has been reviewed. A key is provided that explains the coding systems used in the listing. Vendor addresses are also provided. (Prices are not given.) (ML)
