> This seems to be what's often called the "flipped classroom" approach.

A flipped classroom falls short of tutorial instruction. Often, it's just recorded lessons presented outside school time to leave more time for using the classroom in other ways.

Homework in conventional primary classrooms is not helpful and may be harmful, and as best as I can tell, this includes flipped lessons and textbook readings. We've got a pretty big mountain of data accumulating on this topic.

I'm trying to flip some topics in AP Microeconomics and it's really hard to do in an effective way.

Actually: I find in AP Micro I am doing things much closer to how you describe, because I'm micro-optimizing for (students doing well on the AP Micro exam) instead of (producing students that I feel understand economics in a generally useful way).

> "quick feedback" features of DI

I think pretty much everyone agrees quick feedback and measurement is valuable. Having one clean expected answer that the class says together is one way to get this, and I guess it's perhaps the one that requires the lowest instructor skill and thus is most repeatable.

But I would say, for example, that Khan Academy does it much better-- pacing things to each student, providing individualized feedback, supporting spacing effects through mastery challenges, and allowing questions whose responses would not be said the same by all students. It's trickier, though: you need to stand in the back of class to tamp down on device misuse. And in the end students do work in exchange for recognition from their instructor in a well-functioning classroom, which is hard to get if they're spending most of their time trying to please a computer.

Somewhat offtopic, but I'm surprised that "device misuse" is that big of an issue. I suppose that these are most likely school-provided and school-administered devices, so they should arguably allow for some sort of time-based kiosk mode where the student is restricted in what they can do on the device. Aside from that, I do in fact agree wrt. on the potential of Khan Academy and similar systems - they seem to have the potential get closest to the "Bloom's two sigma" result of fully individualized instruction.

In our case, schools purchase and bring their own devices past elementary school. But even with technical measures, there are a nearly infinite number of ways to screw around. > they seem to have the potential get closest to the "Bloom's two sigma" result of fully individualized instruction. They don't, though. In my experience, there's 3 reasons why a student will devote effort to improvement in a classroom. In order of their efficacy and difficulty to instill: 1. Pressure from grades/the gradebook. In my experience, this is only weakly effective. Even in my environment where families are really achievement focused. There is too much of a delay; even if things are updated in Khan or the gradebook nigh-immediately, the measure doesn't become consequential for a long time. 2. Social pressures in the classroom: desire to not look foolish; relationship with an adviser; desire to please the teacher; effects of appropriate praise; desire to do fun things that other students are doing. 3. True interest and independent engagement in the subject. You could alternatively view this also as a scale of how quick and effective feedback is. By #3, the student starts to measure themselves. Khan or DI will have a hard time taking a student to #3. Khan's a super-strong, super immediate version of #1; DI is a very weak version of #2 (but possibly the easiest to implement).
