What Works Clearinghouse is a website that evaluates curricula/methods based on studies and outcomes. You can look up stuff my grade, subject, desired outcome. It’s pretty interesting to poke around there.
Thank you for posting this. I tried to find the site myself the other night while watching John Mighton’s lecture. I enjoyed the lecture also, especially the part about normal environments producing wide bell curves with large standard deviations and then enriched or restrained environments producing narrow bell curves with small standard deviations. It made sense, but I had never thought of it that way
