At present, there is very little tolerance for error in the classroom. That is one of the reasons students cheat. It is one of the reasons students are nervous. It is one of the reasons many students are reluctant to speak. It is certainly the reason why students (and the rest of us) fight so hard to justify what they think they know. In varying degrees, being wrong is a disgrace; one pays a heavy price for it. But suppose students found themselves in a place where this was not the case?
-Neil Postman, The End of Education
Sounds like a good start, but we have to get rid of the WASL first.
