From Ellen: If you haven't had a chance yet, please read Learning Forward's article, "A New Game Plan - Professional learning redesign makes the case for teacher voices" published in The Learning System. I think many of the ideas captured here will resonate with you and your work. This article may be appropriate for your monthly coaches' networking meeting discussions.
"When school system leaders succeed in developing a culture of data use and analysis to improve professional learning, educators use data to monitor and evaluate the short-term, intermediate, and long-term effects of professional learning."
