This book provides a more comprehensive discussion of collaborative school efforts than any other single source currently available. Specifically, multiple disciplinary perspectives are presented, addressing the complexity or "promises and pitfalls" of school collaboration efforts. The book is organized in terms of major considerations in school collaboration initiatives—the organizational structure; the change process; inter-agency and intra-school collaborative efforts; and implications for instruction, leadership, and leadership preparation. Also, the book informs the design of educator preparation programs emphasizing collaborative schools and cross-disciplinary teaching.The chapters address many issues regarding school collaboration, such as which organizational structures will enhance collaborative efforts; which change processes are important in building school collaboration; the costs (in effort, energy, time, or other resources) of collaborating with other external agencies; how teachers' work can be redesigned to enhance collaboration between teachers and the anticipated outcomes for teachers and students; how educators can overcome their separate role socializations to build collaborative work relationships within schools; and the implications of school collaboration for teaching and learning, school leadership, and leadership preparation. The closing chapter offers five synthesizing issues or dilemmas for school collaboration.
