I agree that this is essential. But the issue here is more about what you're not doing. ie., yes, every lesson must be a performance. but it must also be a challenging one. learning is no a michael-bay movie, it is a stanely-kubric: a wonderful light show, yes -- but challenging, stressful, opaque -- and requiring your active participation. What happens when you use student evals as guides to effectiveness is that learning becomes less challenging. (as evidenced here: http://faculty.econ.ucdavis.edu/faculty/scarrell/profqual2.pdf http://faculty.econ.ucdavis.edu/faculty/scarrell/profqual2.p...) I work in high-end commercial education, where this effect -- to me -- is quite clear. But its less obvious how to deal with it. Customer satisfaction is more important than education, to selling education.
