A longitudinal study was undertaken in Alberta to pilot an evaluation model which was devised by Robert E. Stake and which could provide feedback on the merit and effectiveness of vocational education in the provincial high school curriculum. Using both student records and questionnaires administered to the students, information was gathered over an eight-year period ending in 1977 about 2,754 students who were in grade 11 in 1970. The study focused on the following areas: course selection and student programs, occupational achievements, student evaluation of present curriculum, and student recommendations for future directions in curriculum. Areas found to be in need of further research, development, and evaluation included (1) modern languages and fine arts; (2) dropout rates from business education, science, and second languages; (3) language laboratories and library research; (4) counselling services; (5) extracurricular programs; (6) experiential work programs and preparation for the world of work; and (7) the division of the school year into semesters. Besides identifying problem areas and indicating program effectiveness, the results of this study provided curriculum planners and resource allocators with guidance in future curriculum directions and emphasis. It was recommended because of the success of this pilot project that an ongoing evaluation program be established in the province. (ELG)
