Thanks to a post at The Engineer’s Pulse, I learned about Harvard Professor Eric Mazur. He’s done a lot of work — perhaps it could be called teacher action research — on the advantages of peer work over lecturing as an effective instructional tool.
You can read more about his work at a recent Harvard Magazine article titled Twilight of the Lecture. I’ve also embedded below a talk by him about his work.
I’ll be adding this post to The Best Posts Questioning If Direct Instruction Is “Clearly Superior.”
