In response to Helen's request for input on new features, I would like to make a case for an option to include extra credit assignments that allow student's course or category totals to exceed 100%. Basically, this is an extra credit assignment where any points earned are added to the student’s total points earned for the course or category, but the total possible points in the course or category is not increased. This is not currently a feature in Moodle. In my experience, this type of extra credit is very common in American secondary and post-secondary education and is a high priority for our faculty. If you would also like to be able to include extra credit assignments of this type, please vote for this issue in the tracker: http://tracker.moodle.org/browse/MDL-12380
For many of us who are in environments where this type of extra credit is widely used this is an essential feature. In my search for a solution to this I have seen quite a few similar posts on “how do I do extra credit?” I think because this concept is so pervasive in our environment, many users assume that there is already a way to accomplish this and that they just haven’t figured out how to use it. However, it isn’t currently a feature at all.
Additionally, I suspect that many of us in environments where extra credit needs to be used would like to see such a feature compatible with the "simple weighted mean of grades" aggregation strategy so that instructors would have the ability to use extra credit AND show students an accurate "running total" through the "aggregate only non-empty grades" option. Some discussion on this has already taken place here: http://tracker.moodle.org/browse/MDL-12942
