What if it is possible to spend a lot less time learning that with newer classroom methods (ed tech doesn't have to mean whiteboards and apps, teaching methods are technology too). We can make a good house without metal fasteners using hand tools and nothing but muscles. But that doesn't mean that a house built using brushless power tools in 1/4 the time isn't also a good house. More directly: I conceptually understand a lot of algorithms that I read about. For me though, the ones that I learned by coding them and running them are the ones I understand much better. Hand written notes on a lecture do not guarantee complete or correct understanding, and there is no mechanism for checking.
