Non-cooperative approaches, by contrast, almost always involve duplication of effort, since someone working independently must spend time and skills on problems that already have been encountered and overcome by someone else. A technical hitch, for example, is more likely to be solved quickly and imaginatively if scientists (including scientists from different countries) pool their talents rather than compete against one another.
Alfie KohnThe difference between a good educator and a great educator is that the former figures out how to work within the constraints of traditional policies and accepted assumptions, whereas the latter figures out how to change whatever gets in the way of doing right by kids. 'But we've always...', 'But the parents will never...', 'But we can't be the only school in the area to...' - all such protestations are unpersuasive to great educators. If research and common sense argue for doing things differently, then the question isn't whether to change course but how to make it happen.
