And not to speak for Mr. Nehrling, m, correct me if I’m mistaken, but what I think he is saying is that a classroom which welcomes debate and discussion on issues is a more dynamic, intellectually stimulating experience. And I agree with that on principle. Where we disagree is on practicality. NS, you brought up some good points of why that would (sadly IMO) not be practical.
Yea, that pretty much covers it.
