> how high school students need simplified versions That's how I interpreted it. One problem with 'ladders' (i.e. intentional use of simplified explanations) is that if someone is taught the simplification but never realises there's more to it, they can think they know how something works when in fact they don't, which could be worse than not knowing at all. That set of qualities (being wrong but certain they're right) reminds me of the 'midwit' meme.
