The evaluation report is one of seven produced for the Occupational Exploration Program (OEP), a series of simulated occupational experiences designed for junior high school students. Describing the pilot testing of the simulation dealing with product services, the report contains sections describing the simulation context, evaluation procedures, results, and a Reviser's Information Summary (RIS). In the simulation dealing with bench electrical repair, students had the opportunity to repair defective transistor radios, provide supplies to product service personnel, or direct other product service workers. Occupational roles included foreman, repairman, and supplyman. The experimental design involved two Colorado schools, with a total of four experimental and four control groups involving 87 eighth and ninth graders. Instrumentation included knowledge and affective testing, student and teacher questionnaires, and a panel review. Analysis of variance and other descriptive statistics were employed, and reliability estimates were calculated. Analysis of variance results revealed that the simulation had a positive impact on both the student's occupational knowledge and occupational preferences. The RIS records and extrapolates trends related to the strengths, weaknesses, and recommendations from all data sources. Appended materials include the evaluation instrument used and the observer form. (MW)
