This main volume (SP 002 155-SP 002 180 comprise the appendixes to this volume) explains the ComField (competency based, field centered) Model--a systems approach to the education of elementary school teachers which entails specifications (1) for instruction and (2) for management of the instructional program. In an overview, the ComField Model is described as a process; the conceptual frameworks on which it is based are detailed; and specifications for instruction and management are outlined. Part 1 provides specifications for the instructional program in terms of (1) entry behaviors, (2) instructional competencies (three phases include foundations, laboratory, and practicum), (3) noninstructional competencies, (4) facilitating competencies, and (5) the personalization of professional competencies. Part 2 details specifications for program management, including explanations of the nature of the management system--instruction, policy, adaptation, program execution, supply, personnel, research and development, costing, information transmission, and evaluation. Factors involved in implementing a ComField based program, including commitment, resources, adaptability, and time, are considered in Part 3. ED 018 677 is a related document. (SG)
