@CobaltKobold:
No rigorous, repeatable studies, sadly. Just noting that a lot of people who read material where violence is a morally acceptable way to solve problems end up behaving violently (myself included). It gave an answer where none was before, and so I exercised the answer.
The point, by the way, is that it doesn't matter so much when you leave un-mathematically inclined people in the dust and they choose to change careers. Not everyone can be good at everything, and very few people actually need to be good at mathematics (i.e., mathematicians need to be good at mathematics. Everyone else can get by with a little bit of computation from time to time).
Anyway, the first example has multiple easy solutions, since it will be objectively clear that the student is not doing well. Namely, create a remedial section, hire a tutor, or other solutions that fit (more exist, but I'm not familiar with this area.) (Also, I'm not sure why choosing to not pursue something one performs less well at is a bad decision.)
I still consider that "catering to the lowest level" (since large numbers of resources are going to go to the people who couldn't keep up), but I largely agree with you.
As far as the second issue, defined here to be the sort of pervasive social muck that makes it pretty much impossible to act at a reasonably mature level... well. Do you know what they do with the second issue, at least where I'm from? They put up posters with facial expressions in all the rooms from elementary school and middle school and, provided that you're not too crazy, that's just about it. If you're quiet and shrink from social contact, that's fine. If you still can't read those damnable facial expressions, that's fine, too.
Nothing really matters as long as you're at the very top of that intellectual curve.
Provided that you're not a total rapscallion, there's no time for you, and no one is going to help with whatever's plaguing you. This isn't exactly scientific, no, but it's a distinct trend. Teachers don't have time for a lot of things we all wish they did.
So, here's the question: provided that these people aren't causing too much trouble, should we spend the resources on them or not? Eh... I suppose it doesn't have that much to do with censorship, but at the same time I'd say that raising the lowest social maturity bar more aggressively is something we need to do before we can start really thinking about removing censorship in schools.
As that's the case, I don't see why they don't just move the collegiate dictionaries to the high school and only give the kiddies access to kiddie dictionaries.
I was using collegiate dictionaries for my spelling lists in second grade. It would have been a distinct problem--what you're suggesting now is the blunting of the upper level of intellect. I'll admit that I brought the dictionary from home, but it would've been a hell of a lot more convenient to have one in class.
