Block scheduling Not helping high school students perform better in college science InsideUVA
Seemingly little to do with History and Interactivity, except for this: we just know so little about what works and what doesn't in education. Witness the recent switch to "Block Schedules". Classes are too short to get anything done, went the cant. Make them longer and kids will learn more.

Well, there may be some merit to that if a class is really flowing and all of the students are highly and intellectually engaged.

But of course not all classes are like that, and many students are not at all engaged. So here we find some results on how block scheduling helped science students by the time they arrived in college.
