Many leading voices of the ed reformist movement have started calling for an emphasis shift from policy to practice. That makes a certain amount of sense; the last two decades provide plenty of evidence that policy can interfere with practice far better than aid it, and ultimately students are educated by classroom practices, not by policy.

But when discussion among edupolicy wonks turns to the use of best practices in the classroom, one complaint inevitably surfaces: “Why aren’t more teachers using the proven work of Dr. Wisewhacker on teaching [insert topic here]?” Why is the path from great idea-hood to widespread classroom practice so hard to navigate?
