Attendance in class is expected.
By 8:00am (two hours before class starts), students must send me email with a set of three questions about the material being covered that day. I encourage you to also bring a printout of these questions with you to class, and use them as a springboard for discussion. Your email must have the subject line
Subject: Vis submit Qnumwhere num is the lecture number.
Your submitted questions/comments should be thoughtful, and clearly show that you've done the reading and reflected on it. They do not all have to be phrased in the form of a question, a comment is fine. If you genuinely are confused by some aspect of the reading, then it's useful and legitimate to ask for clarification. However, simply asking something that you could trivially look up yourself is not a good question. As with any written work that you hand in, I expect correct grammar and spelling.
