This report provides information about the 54-hour module in ownership and/or management of a small business, Mind Your Own Business, that was taught to all twelfth grade students at the Norwich Regional Vocational Technical School. A twelve-page abstract outlines the topics/ business principles studied, describes the program, and summarizes setting, funding, and program design. The introduction discusses the problem that led to development of the course--lack of student understanding of business skills--reviews pertinent literature, and lists 17 project objectives. In the next section entitled Summary are presented results of the pretests, unit tests, posttest, two-part student evaluation questionnaire, and class of 1980 graduate survey. These conclusions are reported: the course is a model for other vocational-technical schools, overall program rating was good, posttest scores were higher than pretest scores indicating learning, and students indicated a need for the program. The final section, Project Design, overviews activities, participants, methods, evaluation, time schedule, results, and dissemination. Appendixes, amounting to approximately one-half of the report, include a bibliography, tests, questionnaire, survey, test results, and sample materials. (YLB)
