Of course my question is: Do you have a good way of assessing the outcomes
of these lectures?
Joe Redish found that the standard lecture/lab/recitation courses pushed
students toward more novice like views, while studio style courses made them
somewhat more expert like. So how do you know that the student attitudes
are actually changed? For example based on experience, one estimage that I
have heard is that it takes about 160 hours or so to change teacher's
paradigms. Paradigms are very resistant to just short term interventions,
especially lectures.
They will gladly parrot back what you tell them, but then you need an
independent way of assessing that does not involve just looking at what they
parrot.
