When teachers work in successful teams, they have an opportunity to observe each other at work in order to improve their own practice. They can get group assistance with problem-solving; together they can examine student work, address issues of classroom management, learn a new curriculum, provide support for new teachers, and give veteran teachers roles as mentors. What teachers are unable to accomplish alone, or only with great difficulty, they can accomplish more successfully in a team. The Transformative Power of Teacher Teams is designed specifically for teachers and administrators, in their specific context, to enable them to develop their own unique teacher-teams that will directly improve both teaching practice and student learning. Further, the book fulfills the promise inherent in its title '¬ ; it demonstrates not only how effective teams can transform the practice of teaching, but also how its model of teacher collaboration can transform the culture of schools into communities of learning that foster and value teacher leadership.
