" feeling is, that if you are not lecturing at least 50% of the time,
the students aren't going to learn much."

Are you implying that one cannot learn by reading, experimenting, problem
solving? Or is it the "much" that you are emphasizing -- that students
who learn by other means do not learn as much content?

I would disagree. I think that students learn, sometimes despite what
we do in class, by their own effort. In New York State we have to finish
the textbook for the Regents exams. Therefore, "covering the content"
is a the predominant concern, unfortunately. If the students are not
engaged in constructing their understanding of the content, however,
very little of what they learned for the test is retained.

In Schoenfeld's research on problem solving, he noted that mathematicians
can reconstruct forgotten knowledge, while students relied on what they
could recall. That is, if students could not remember the formula for
the sin(2x), they give up on the problem. The experienced person (I
hesitate to say mathematician because this would preclude school
math teachers), however, reconstructs this from something they do
know (perhaps sin(x+y)).

I bring this up because in order to be able to reconstruct something
you have forgotten, you much understand it at a level seldom attained
by listening to a lecture. I often lecture, but I realize that I am
covering the material, which is not guarantee my students are doing
anything other than taking notes. In fact, the higher the level of
the course, the smaller amount of material actually is digested during
the lecture. When I was a grad student, we often joked that we were
merely a vehicle for converting the prof's spoken word to written
words in our notes. The content was digested later when we tried to
read our notes.

A lecture in a darkened room is deadly.\
