As special educators we are constantly finding ourselves in co-teaching relationships, whether it is with Instructional Aides in our own classroom or with general education teachers in their classrooms. Co-teaching is great for the students. It improves our teaching, pushes us to think beyond our own opinions, allows us to get two sets of eyes on a student's progress, gives us someone to bounce ideas off of, and helps manage behavior. The benefits of co-teaching go on and on. I love it and prefer co-teaching to working in isolation. That doesn't mean it isn't hard.
The problem is that no one tells us it is going to be hard. In about October you start to think you are doing something wrong because it IS hard and nobody warned you. Aren't you supposed to have that idyllic co-teaching relationship your professors told you about?
