Hi Dennis: I don't give extra credit. I could provide a lengthly response, but in short, it creates as many problems as it solves. Education aside, these are students, there to learn something they need. EC seems to emphasize points and grades, less about achieving higher leraning outcomes. Grades are useless if the student has missed or doesn't understand key information. Just my opinion. Each teacher and institution has to come up with their own policies and guidelines. If its done, I'd strongly suggest having very clear expectations and guidlines stated at the outset, then follow them firmly and consistently. Regards, Barry
