I just fixed the on-line grade book to accurately reflect the attendance algorithm. Within minutes students are emailing asking what just happened to my grade?.

The answer (which in the pre-blog days I would have to give in individual email replies): as stated in the syllabus and several times in class, you earn 10% for attendance once you have been at seven quizzes. If you haven’t been at seven of the eight so far, you’re running a zero for attendance.  There are two more quizzes to come. If you want the attendance credit, come to class.
