Co-teaching also allows the two teachers to take turns leading different lessons. The two teachers use each other as a resource to benefit and advance the lessons they provide to their students. The third video showed the benefit of an instructional strategist come into the call room to evaluate what is being taught andhow, as well as how well the students are understanding what is being taught. Following her weekly observation, the strategist meets with the teacher and coaches the teacher on ways to better use performance based assessment. This strategist sits with the teachers to help them strengthen their lesson and brainstorm ideas to use within the classroom and how to better plan lessons. What do you understand more deeply? What do you still wonder?These examples showed me how important this collaboration is to benefit the classroom as well as how having a mentor, peer, coach, or strategist come into the classroom to give you a fresh view on what is working and what could do better. However, I still wonder for the strategist or coaches is this something the teacher can set up to occur or does it have to be approved and set up by the district or school administration?
