This document provides critical reviews of 18 computer software programs designed to provide some form of substance abuse education for students in elementary and secondary schools. Evaluation and review procedures used to create this publication are discussed in the introduction and the products which were evaluated are listed. Overall results of the review are summarized in a section on findings and an evaluation summary table gives the final scores each program package received on each evaluation criteria used. The findings section notes that: (1) 11 of the 18 programs were linear tutorials with very little branching and all of the tutorials were very text-intensive, requiring a considerable amount of reading; (2) most of the packages did a fairly good job of stressing the harmful effects of alcohol and other drug use, but legality of alcohol and drug use was addressed in only a few instances; (3) none of the programs were intended to be comprehensive for all grades; and (4) programs received low scores for supplementary materials which accompanied the program disk. The products reviewed were rated as good at accurately presenting content, avoiding stereotyping, and being easy to use. For each of the 18 programs, the product description section lists the program title, hardware needed, cost, copyright year, audience, a brief description, possible uses, strengths, weaknesses, and additional comments. A list of producer contact information is included and the software evaluation form is appended. (NB)
