To me, it seems that the key is to base course evaluation on the levels of behavioural change as a result of the course and to surface that to the students. Admittedly, the first part is tricky. How do you measure changes in behaviour without resorting to the typical grade-this-module pattern? The second part is a bit easier. But it needs to be done carefully. Otherwise it sounds like a very blunt “Look! This is what happened to you because you’ve taken the course. Great, isn’t it?”.
