- What you say is perhaps the most surprising and fascinating discovery you made when putting together your book range. - For me, it was this idea that there are things that you can do that cause really rapid short-term improvement that can somehow they can systematically undermine your long-term development. I mentioned that the single study that was probably one of the most surprising in the book to me was this one that was done at the US Air Force Academy where they would get in a freshman class, you know, of whatever thousand students or some hundreds of students and those students all had to take a sequence of three math courses, so it's Calculus one, Calculus two, and then and then a third course. And they were randomized to Calculus one to a professor and then rerandomized for the second course and then rerandomized for the third course and they all take the same test. And so the findings of this study was that the professors who are the best at promoting contemporaneous achievement that is who students overperformed on the Calculus one test the most compared to the baseline characteristics they came in with. Those students then systematically underperformed in all the follow-up courses. And what the researchers concluded was that the way to get the best results, and the Calculus one test was to teach a more narrow curriculum that involved a lot more was called using procedures knowledge, where you learn how to execute certain procedures and algorithms. And you don't learn more of what's called making connections knowledge where the curriculum is broadened. And you're forced to kind of connect types of, of concepts and learn how to match strategies to types of problems as opposed to just execute procedures. And so when they moved on into these other courses, those students who had the more narrow curriculum were systematically undermined. And that's sort of one of the themes that runs through range that the things you can do that seem the best in the short-term, sometimes under term undermined long-term development. And I thought that was just an amazing display of that and an amazing study. - Well, so it's sort of like the items that were being covered on the final test it sort of like. Yeah, he drilled on real good. - Yeah. - Over and over and over again, and thoroughly. But sort of at the expense of getting some broader conceptual understanding of how this the math number Calculus stuff is working, I guess more more globally. - Right. And that's what they then would need. That's what would then help them kind of scaffold later knowledge so they didn't do as well in those other classes. And so that's really kind of worrisome.
