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.

When was the last time you spent the entire day with only 42 year olds?

Saying you taught it but the student didn't learn it is like saying you sold it but the customer didn't buy it.

Punishment and reward proceed from basically the same psychological model, one that conceives of motivation as nothing more than the manipulation of behavior.

In education, parody is obsolete.

Each time I visit such a classroom, where the teacher is more interested in creating a democratic community than in maintaining her position of authority, I’m convinced all over again that moving away from consequences and rewards isn’t just realistic - it’s the best way to help kids grow into good learners and good people.

Punishments and rewards are two sides of the same coin and that coin doesn't buy you much.
