Designed to assist chemistry teachers in selecting appropriate software programs, this publication is the third in a series of six teacher's guides from Project SERAPHIM, a program sponsored by the National Science Foundation. This guide is keyed to the chapters of the text "Modern Chemistry." Program suggestions are arranged in the same order as the chapters of the textbook and are classified by topic and by type of classroom use. Information on each program includes: (1) name; (2) disk number; (3) topics; (4) grade levels; and (5) a description. Guidance is also offered regarding methods by which each program can be used most effectively. Summary lists of recommended programs for Apple, IBM, and Commodore systems, as well as for other microcomputers, are provided. Specified in these lists are the SERAPHIM disk number, the hardware availability, the program's name(s), and the recommended chapters for use. (ML)
