I've had this book for a few years now and retread it many times. Most of the ideas they discuss stretch our minds and "giving yourself an A" sets off alarm bells if you are an educator. But they are right. Forcing a class of 30 students onto a bell curve is entirely arbitrary. That is particularly true when admission to the class required a rigorous screening.

But it is the fear that some will take this approach as an opportunity to slack that bothers others. If you've participated in group work you don't need an explanation.

I'm looking forward to reading your forthcoming account of this experiment!
