Honestly whether or not this was effective seems less important to me than the adoption numbers. Text book reading in this course was 10-15% at baseline ... but this AI thing got 90% voluntary usage ungraded. Even if its worse per-hour than a textbook, you're now teaching 6x as many students _something_ instead of teaching a small minority everything. So really it just becomes an optimization problem at that point because most students are at least in the funnel/in the running to learn something. The paper kind of proves this itself ... they tweaked the quize formats mid-semester and where able to iterate which you can't do on a textbook that nobody opens in the first place
