This study was performed to develop a competency-based professional education sequence (termed "spiral curriculum") which would provide pre-service and in-service training for new vocational instructors hired directly from trade and industry. Specific objectives were (1) to identify a comprehensive list of professional education competencies needed by a vocational teacher, (2) to select survival competencies and identify the appropriate level needed for first-year teachers, (3) to structure a pre-service educational experience, (4) to develop curriculum plans for follow-up in-service training, and (5) to articulate the plan into the existing Wisconsin certification requirements. A comprehensive list of first-year survival competencies was developed for phase 1 of the spiral curriculum based on a review of studies which list professional education competencies needed by vocational teachers. Phase 2 competencies were selected for follow-up in-service and met the requirements of two courses: methods of teaching and course construction. A curriculum management system including a student competence evaluation system was devised to provide a structured framework for effective use of the performance based modules. In phase 3 students will complete courses in classroom evaluation, principles of vocational education, educational psychology, and introduction to guidance. (Competencies identified for each phase are appended.) (LRA)
