"the most ergonomic keyboards are those that require the least amount of repetitive motion"
Not sure I can agree with that. I was using one of the Apple keyboards for quite a long time while running liveops on an online game (which meant rapid response whenever incidents happened, jumping into shells and constantly typing like my life depended on it), and developed fairly severe wrist problems within a couple months. To the point where I almost had to leave the job on disability, per my doctor's orders.
On the recommendation of a friend, before taking that step I tried switching to a Kinesis Advantage for the better wrist alignment and less "hard" keystroke bottom as compared to the chiclets on the Apple keyboard. It was a bit of a learning curve (~2 weeks to get up to full typing speed when using it every day, a couple more to push past it), but at the end of it my wrists got better almost instantly, and I never had problems again. My typing speed went up as well.
I'm not sure how much of that improvement is due to the better alignment of keys (there's almost no hand movement when typing, and your wrists are always neutral) and how much is due to the bigger key action and softer bottom, to be fair.
Edit: it's worth mentioning that I'm also a boxer and a piano player, so my wrists take a lot of abuse on a regular basis. YMMV and if you're not having problems, I definitely found the Apple keyboards to be very easy and fast to use.
Related to that, I think one of the major problems is to motivate kids to do their damn homework, as one of the biggest hindrances to motivation is lack of comprehension. That sets in very quickly if kids only think about the material during class. Once a student drops behind, they are all but lost to you unless you're doing one on one tutoring where you can backtrack without wasting a whole lot of people's time.
I spent a while as a tutor, and I was always amazed that parents were more than happy to spend $100/hr for private tutoring, which most of the time just amounted to overpaying an over-educated person to babysit your kid while they do simple homework that they could very easily have worked through themselves, but just didn't. Yeah, I was also available to answer questions, and clarify things, and I was very good at it, but fundamentally, the most helpful thing was just that the kid was forced to be there mentally.
Crazy idea alert: why not save some money and pay your kid $10 or $20/hr to do their homework rather than paying me $100/hr to watch them do it? I'm sure dollar-for-dollar this would be far more effective. If need be, pay me the $100 a fifth as often - while I love the money, I honestly feel like most of the time I spend tutoring is wasted since the kids see it as a substitute for their own personal work, not as a supplement to it. I've often wondered if setting up an automated, pre-funded allowance system based on online homework time (or productivity, or some combination) might help this situation. I know that the idea of paying (bribing) kids to do what they "should" be doing anyways seems wrong philosophically, but I really think it might be more cost effective in the end. And if the old line that "school is your job" holds true, then perhaps kids _should_ receive a little money up front for work, especially if they won't do it otherwise. Yeah, rewards come later and all, but how many rational adults would really be willing to work at 100% effort for twelve years with only an assurance that they will be compensated for their labours with some unspecified and uncertain amount later? (no offense intended to anyone that took tech jobs for stock options during the dot-com bubble, of course :) )
