It's also worth repeating that "scheduled class time" may well not be spent in traditional classroom activities -- or, indeed, in the classroom at all. The bottom line is that we budget eight learning hours per week. This class is scheduled, like any other three-credit, one-term class, to meet for 150 minutes every week. I occasionally use scheduled class meeting time interchangeably with other kinds of learning time -- we might be in the library or the computer lab, or working individually or in groups elsewhere for some of the time officially identified as "class meeting time." Even so, you should plan on being available for the whole scheduled class time every Monday night. We won't always meet formally for all that time, but we will need the flexibility to plan on everybody's availability.
A consequence of this class schedule -- that is, that we meet only once a week -- will mean that often tasks are scheduled with deadlines between class meetings, so that, for example, people can respond to a task and see what others have done before we meet again. These deadlines, like most in this course, and most of my courses, are inflexible, because they're real. Often I need to set up a time by which something needs to be done, so that others can respond to it: if it's not done, they can't respond, and the point of the assignment is lost. That's why my policy is that, for purposes of establishing a "minimum mark," late assignments aren't counted (for more on this, have a look back at the evaluation document).
