The most valued means of support and learning cited by new teachers at Poland Regional High School in rural Maine are the collegial interactions that common workspace, common planning time, and common tasks make possible. The school has used these everyday structures to enable new and veteran teachers to converse about curricular and pedagogical decisions, student learning, administrative logistics, and professional learning. Teachers share classrooms. Co-teaching teams, cross-curricular grade-level teams, and content-area teachers share office space. Common planning time enables team teachers to plan their curriculum together, assess student work, interact with colleagues, and consult with parents and students in a group setting. Many structural features of the school curriculum frame common tasks for teachers and require collaboration, such as standards-based assessment, advisory groups, grade-level teams, an interdisciplinary curriculum, and classes taught in common.
