A study of career education was done in California to develop a conceptual model that describes the cooperative activities (intradisciplinary, interdisciplinary, multidisciplinary) within the school setting, identify promising practices that use cooperative activities to enhance the implementation of career education, and make recommendations regarding the incorporation of the results into an inservice program media presentation. A list of six factors (administrative, personnel development, community, guidance, instructional, and curriculum) used to organize and structure school programs was prepared to direct the inquiry about cooperative activities (helpful relations, actions, and pursuits carried on between school resources and program factors which are aimed at the accomplishment of a goal). Data were collected from six career education demonstration sites in southern California via a telephone interview with a site contact person followed by onsite systematic exploratory interviews with the contact person, school personnel, students and parents, and members of the business, industrial, labor, and general community. The nine promising school practices identified are curriculum legalization, communications, community resources, instructors' handbook, career guidance centers, careers fair, minisocieties, community classrooms, and construction technology. (Each practice is described and strategies for and considerations affecting implementation are discussed; six conclusions are presented; and the program factors, telephone interview form, and systematic exploratory interview form and technique are appended.)
