This guide is designed to help the educational practitioner understand more fully how teachers fulfill their roles in integrating vocational and academic education. A description is provided of the field study during which more than 100 teachers, counselors, principals, and administrators were interviewed at 10 school sites using the Behavioral Event Interview (BEI) to explore behaviors, thoughts, and feelings of particular events both when teachers were effective in integrating vocational and academic education as well as when the interviewee would have changed what had been done. It discusses how a write-up was prepared for each event and information from write-ups was analyzed and grouped according to major themes and subthemes. The major section of the guide contains discussion and summary statements related to teachers' roles in integration drawn from the write-up analyses. Roles are described from the perspective of four major themes: faculty cooperation, curriculum development, instructional strategies, and administrative practices and procedures. The comments within each theme, arranged by subthemes, provide an easily accessible reference for educational practitioners in various stages of implementing integration; characterize roles that academic and vocational teachers must fulfill to achieve the integration successfully; and link the roles of teachers with administrators' practices needed to support these roles. A final section summarizes the stages of integration within the three themes and teachers' roles within those stages. (YLB)
