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 manufacturing production, the report contains sections describing the simulation context, evaluation procedures, results, and a Reviser's Information Summary (RIS). In the simulation, students set up and put into operation a 38-step assembly line producing extension speakers for transistor radios. Safety rules, administrative procedures, and job training were introduced. Occupational roles included supervisory positions and assembly line production. The experimental design involved two Colorado schools, with a total of four experimental and four control groups involving 77 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 did not have a positive impact on student occupational knowledge but did have some positive impact on student occupational preferences. The RIS records and extrapolates trends related to the strengths, weaknesses, and recommendations from all data sources. Appended materials include the evaluation instruments used and a teacher evaluation log. (MW)
