All the 11 publications in this annotated bibiliography explore the department head's dual role as teacher and instructional leader. Three articles characterize principals' role as managerial and recommend that primary instructional and curriculur responsibilities be delegated to department heads with clearly designated positions in the school's administrative hierarchy. According to the third article, a team approach involving four key stages (diagnosis, allocation, implementation, and evaluation) works best in secondary schools. At least three publications address the role conflict and ambiguity experienced by heads as line or staff supervisors, change agents, or helping professionals susceptible to burnout. The eighth publication discusses one chairperson's facilitative approach to peer review in an English department. The ninth article describes a leadership training program to help secondary school principals and department heads work more competently with teachers, use meetings more effectively, and improve performance of long-range planning and evaluation functions. The last two publications discuss department head responsibilities in detail; both stress the value of shared decision making, cooperation, and the evolution of an effective work group or "esprit de corps."
