Administrators and coaches desire increased collaboration between special education and general education teachers in implementing effective co-teaching. Research has identified many components for successful co-teaching, including interpersonal communication, physical arrangement, familiarity with curriculum, curriculum goals and modifications, instructional planning, instructional presentation, classroom management, assessment, and support of administration. Because the most effective co-teaching teams use a variety of these co-instructional approaches, administrators and coaches will need to observe pairs more frequently to get a deeper understanding of what is occurring in the classroom. In this session, administrators and coaches will explore commonly used evaluation tools in identifying what to look, listen, and ask for during walk-throughs and formal observations to ensure the demonstration of co-planning, co-instructing, and co-assessing by co-teachers.
