Certainly not before we know on what to act. What I gathered from reading his comment was that we have significant deficiencies in even how to classify good teaching, let alone measure it, let alone promote it. Skipping straight to the promotion part, which is what you seem to be insisting, would merely involve guessing and inconsistency at best. At worst, we would promote the wrong qualities and make teachers worse.

I'm not suggesting that we simply talk and talk and never take action, but it's hard to make the case that we know how to improve teaching given the state of education in this country. It makes good sense to fix our ignorance before acting.
