As I said, I have a way to go before understanding all the subtleties of the Gradebook. Maybe it already does what I want?
What I would like is something like what Questionnaire does: all the students either get the same grade or they get nothing. For tasks such as writing in forums, contributing to glossaries, participating in collaborative tasks... I would like them to see something like "OK" or "Work done" that would be transformed behind the scenes into a numerical score (so that it can be comparable with the scores from Quiz, QuizPort, etc.)
At the moment, I just tell students not to pay too much attention to their gradebook scores because they don't determine their final grade.
Not sure I'm being clearer.
PS I'd love to be able to find again some research I read years ago. We all know that having two teachers grade a student gives a more reliable result than just one. And three are more reliable than two, but are 33 more reliable than 32? I don't know how they went about it, but they determined that after a certain point, adding more graders does not significantly improve reliability... and also that the cut off point is different for different subjects. If I remember rightly, for maths it is something like 12 graders and for philosophy... 200! But maybe not for your branch of philosophy. Logic, isn't it?
