A project was conducted to determine if interactive video programs could produce positive results in literacy programs. During the project, staff from a technical college developed a task analysis, curriculum, and evaluation measures for the training of facilities maintenance workers in mathematical concepts. From this activity, an instructional design, workbook activities, and a videodisc were developed. Thirty physical plant employees volunteered for training and participated based on their level as determined by assessment. Each participant worked individually on a prescribed lesson plan for 6 hours per week, completed videodisc units, and used workbook exercises. The project was able to increase the skills of all participants, with those who scored lowest on the preliminary evaluation making the largest gains. There were no significant differences in results based on age or gender. The results of the project indicated that videodisc technology is an effective and convenient method of delivering instruction. A third-party evaluation concurred with the project staff evaluation. Project results were disseminated at conferences and demonstrations to companies interested in workplace literacy.
