A description and evaluation of (1) the development of the 4-column process which completes the behavioral objective data base, (2) the development of the computer retrieval capability, and (3) the pilot testing of the product in high school classrooms are included in this summative evaluation of Project CAREER/CAN. (Goals of Project CAREER/CAN, which is a component of the larger Project CAREER, focused on the development of information and delivery systems which would cut across grade lines and provide career information to students and teachers in Grades K-l4. The Project structure enabled further development of the behavioral objectives product to include four columns of curricular information: prerequisite learnings, component tasks, environment, and concepts.) This report contains a review of the component in terms of project administration and personnel, achievement of stated objectives, and cost effectiveness. Major conclusions presented are: (1) The product is about 90% complete and is a highly transportable product, (2) computer retrieval capability is available for several useful configurations of data, and (3) although the pilot test established the feasibility of using this product in the classroom, it was too limited and ineffectively monitored to provide more than rudimentary data for further product development. Appended are a report from a pilot high school on use of Project CAREER learning activity packages, teacher survey questionnaire, and the editor's manual for 4-column development. (Author/RG)
