It has been my experience as a student teacher supervisor, while observing student teachers, there are instances when a student teacher is in a more supportive role; small group instruction or one to one with a student. There have also been times when I have seen that the Student Teacher's role was rather restricted. Before classroom teachers sign up to be a cooperating teacher for a student teacher program...please research your role. Teachers are so busy so make sure you have some time to enhance your student teacher's learning experience. Take time for weekly conferences, conference with the student teacher supervisor and try to record or observe the teacher candidate while they are giving lessons. When this relationship works and everyone does their part it works out so well for all involved. Its a wonderful learning experience for everyone!
