Hi Marty: I see your strategy. I've always tried to stay clear of using the grading or instructional process to penalize students, as they may adopt a poorer perspective about the class, and some may lose respect for their teacher for "tricking" them. Also, there may be legitimate reasons good students are unable to attend the class on a given day. A compromise might be to discuss some material in such a way that absent students will miss out when those questions are presented on a test or quiz when all are present. There's hardly any argument about "well, it was discussed in class". If attendance issues exist, maybe some programmatic or intitutional policy can be developed to address it if it's a chronic occurrence. Regards, Barry
