This week Pete (@mr_van_w) hate-reads a blog post in which traditionalist takes psychological research out of context to prove a point and uses metaphors that don't make any sense.
John (@jfcatto) shares a fantastic resource from the NSW Department of Education (DEC) and Evidence for Learning. After questioning what the C in DEC might stand for goes through one of their research summaries on Mastery Learning, which may make the "slight" improvement of 150% teaching efficiency.
