I'd question even the basic premise that education is about behavior modification. Unless you define behavior much more broadly than is typical. If you go back to the root word in education  as "drawing out" it is more about self-knowledge than knowledge for behavior change. Even 'learning to do something" would be a more common way to think about education. Certainly no philosopher of liberal education would say that education is about behavior change. If your interest is education, I'd recommend reading more about liberal education, and such books as Parker Palmer's To Know As We Are Known. If your question is really about behavior change, that's an entirely different domain. But I hope you don't imply that education should be about coercion into one particular behavioral path rather than laying out choices that may expose someone's essential character.

Thanks Hendrika for changing the perspective altogether, but then we are interested that a recognizable good pattern of behavior should be an outcome of education. For instance we expect educated person should know  to be courteous, respecting others' right,  loving justice and in my country at least know the traffic rules and the like. As I understand it is an amalgam of both drawing out and taking in to be a true form of education.
