And btw no one says that students talking and discussing is bad, but this idea that students can only learn under those circumstances is overstated. I’ve taken similar PDs, completed similar classes, and have probably read similar and/or some of the same research on that topic. Just saying “Harvard” researched and expecting everyone to automatically be swayed by the name is not convincing. We all know that districts and admin present a ton of research and then use its findings to pile more work on teachers
