It may interest you all to note that one of my evaluations criticised me for wasting valuable lecture time trying to get responses out of students. Sigh. I suppose that as well as illustrating the general unfairness of life in general, this also illustrates the fact that students have different learning styles. The "concrete sequential" students, or to switch paradigms, the ones that are at about 1.5 on Wm Parry's scale, not only want but perhaps need a certain degree of direction. I think the wisest advice I have heard for a while is the suggestion to vary teaching as much as possible, giving something for the top-downers, the bottom-uppers, the general-to-specific and the specfic-to-general thinkers. What this means, of course, is that we will never please everyone all of the time, which if nothing else should be a caution to administrators not to put too much faith in student evaluations! Doug
