Meaning _negotiation_ is slowed and made more difficult if only one person
speaks (the instructor) or has exclusive control of any of the other tools
involved in the discussion. These tools include the chalk or marker if
there is a board on which to draw, the keyboard if a computer is in use,
etc. It has long been quipped in physics circles that to make your point
in discussions with colleagues in the lab you must have a piece of chalk, a
pencil, etc. Michael Roth of Simon Fraser Univ. has been doing interesting
studies with children in science lessons in which these notions seem to be
strongly supported.
I have only small experience with small discussion classes because of the
physics community's excessive reliance on lecturing to large numbers of
students at the same time. (If you can tell one person you can tell
hundreds.) Having had experience with large classes (100 - 150 students)
in which I am intended to lecture but in which instead I try to get
discussion going and having had some experience with some smaller classes
(10 -15 students) it is clear to me that in the large group many can avoid
interaction who do not believe that such is what they are there for. My
sense is that fewer of these folks actually engage in the issues of the
subject when the class is very large than when it is small.
These students can not show up and not be missed specifically unless rather
strong measures are taken to keep track of individual attendance. They can
attend and refuse to engage or participate. They can attend and openly
challenge what is being attempted. I suppose that all of these can happen
in the smaller seminar type class, but my experience is that a much greater
percentage do this in the large classes than in the small ones.
