I think there is some conflation going on. Independent problem solving is critical to learning many skills; especially math and science ones. I think a more useful system may be this, at least for middle school and higher:

- Assign students top-quality lectures to watch and problem sets. Think Khan, MitX etc or similar. (But could be specially formulated)

- In class (Which would be shorter), the teacher[s] go over where the student struggled, had questions etc, and give personal attention where needed based on the previous day's lectures and problem sets.

The conflation here is active learning with respecting people's time and attention-span. Active learning critical, but the article's concerns about the latter are valid.

When I was near the end of high school they introduced essentially this structure in an effort to be more digital. I felt it was inferior to just a regular classes by a lot.

I feel being physically present with the teacher imparts things better, it’s easier to pay attention, plus also you can’t ask a video lecture questions. For the online class like this, the in-classroom teacher was pretty checked out too, so if you had questions they weren’t all that helpful.

If you ever got behind it was actually harder to catch up.

Now that wasn’t using Khan Academy where there are different learning paths and you can focus on areas you’re weak and breeze through your strengths, so I don’t konw how that compares.
