This courseware evaluation rates the Drugs--Effect and Control program developed by Marshware/Marshfilm. (The program--not contained in this document--includes Drugs--Who's in Control and Their Effect on You.) Part A describes the program in terms of subject area and hardware requirements (Apple II, color monitor); indicates its suitability for use as application, drill, tutorial, simulation, or gaming in grades 7-12; and gives a time estimate (30 minutes). Accompanying material includes teacher guides. Availability information includes backup policy ($10.00 within 30 days of purchase). Part B contains the evaluation criteria in eight categories; reviewer ratings appear as yes, somewhat, no, and not applicable, with explanatory comments. Part C summarizes the evaluation. The program received yes ratings in all categories: subject matter, technical presentation, student and program interaction, documentation, student evaluation, work behaviors, and application programs. Reviewers found the program easy to use and a good introduction to drug information and group interaction, but expressed a need for more difficult questions for upper-level students. The program is highly recommended. (SK)
