Learning from experience is a way for teachers to see how teaching works in the real world, not in a textbook. Student teachers can observe from teachers, and they can learn how to teach in a variety of ways, or how to handle disputes between students. Learning from experience is at its best when those teachers reflect on what they learned in classes and lectures. Then they can apply those basic thoughts and principles to their present teachings. The final thing that Shulman talks about is Community.
Teaching is a community.
There are a number of teachers in each school, and they are all striving for a common goal. That is to relay their knowledge to the students. It takes a group effort. The stronger the community, the better the results are going to be. With all of these ideas and thoughts, it is pretty obvious to me that teaching is very much a profession.
