The best way to think of Math198 is as a 2 hour studio
course 2 or 3 times a week. The typical session goes like this.

Chores:
10-15 minutes "housecleaning" to resolve  problems with 
logging in, transferring data, managing files, scheduling 
talks, all the kind of stuff you wish you had a secretary to 
take care of.

Lesson/Tutorial
30-50 minutes. A lesson introduces new material of interest
to all students. So this is most like a lecture, except that
it need not be scheduled nor prepared. In the course of a 
discussion or tutorial an issue may come up that deserves
general exposition. For instance, when the 3rd or 4th student
comes up with a similar problem, I am likely to interrupt and
present an short lesson on the subject.  

A tutorial differs from a general lesson in that it goes 
over material for the benefit of one or several students. 
Thus, the novice programmers will have many tutorials that
are of no benefit to the more advanced students. And vice
versa. Some students will move at their own accelerated
rate, and their tutorials would be over the head of the
novices.

Some lessons include a hands-on, guided lab, where the 
participating students follow instructions. Students who
can complete that assignment on their own are free to
do so. 

Supervised Lab
Here you work on projects and I go around asnwering 
individual questions. This generally happens after the
lesson/tutorial, therefore in the hour from 4-5. So normally,
you should expect to spend that time in a lab too, but
it's better to miss a supervised lab than a lesson. 

This coming spring there will be a modification of this
plan because every other Monday afternoon I have University
Senate or related committee work. Those afternoons will be 
open-lab, unless I can find a lab assistant/consultant. 

We also have CAVE reservations 4-5 on Wednesday and Friday.
So all or some students will be working in the CAVE 
at that time. Early in the semester, it will be with 
other people's programs, later in the semester with
you own program.
