Hi Gloria: I think there is a diffrence between extra credit (extra points given selectivity in lieu of regular assignments), and extra activity (course work assigned by the teacher and applicable for all students, and of course, graded in the same fashion). That's just creative, student centered instruction. But points given to supplement slackers, who have not performed well and want to do extra work just to earn points is not learning, it's just a graing exercise that I try to avoid. Regards, Barry
