A good, fee-paying, school for girls in the UK runs "failure week" to let girls know that risk is good; failure will happen; and that you need to be able to work through it.
Praise effort and work, not just good outcomes, is something that has been mentioned on HN a few times before. What I think would be good (although I welcome correction from anyone with better knowledge of education) is letting bright students help teach slower students. This isn't just for the less able students. Teaching other people strengthens your own skills. You don't have bright bored students causing trouble. You have a teacher more able to help students that need it. Maybe it already happens? I dunno. I went to a school that had pretty heavy streaming.
