Chris I was really excited to read your description of teacher knowledge and how it is relates to teaching. There seems to be a real spit in the conversation on twitter about what is more important and you are either on the teach knowledge camp or the teach skills camp. What is exciting about our conversation is that we are bringing it all together. I will read your link with interest!
I tried to make some sense of this very conversation on my own blog found here. If you have not come across Tara Brabazon she is a fascinating character but manages to explain herself very well.
