One course with 4 students. 2 groups (2 students to each group).
I've create one online assignment, configuring it using the 0-100 scale (default) and "separate groups" (not sure of what that means in the assignment mod).
Then, as teacher, I've graded the 4 student submissions (nothing else) in order to start playing with the gradebook. And have found this (hopefully most of them aren't important, but...):
1- Does the hide/show groups in the gradebook anything? I cannot see the difference here.
2-The info field for each grade item... shouldn't it be bigger (it's a text field, I guess).
3- The module->idnumber... is finally not editable from the grade item form? Only in the calculations window?
<strike>4- Why the total course grade has a calculator? Seems to have no effect.</strike>
4-If the course grade peforms the mean of all the grade items.... then I would prevent to show it with the summatory sign. Seems to indicate it's the sum of all grades instead of the mean.
5- Found various notices/warnings here and there (category edition, general report, preferences...)
6- Found division by 0 on "general report"
7- Found this in "general report": The minimum grade () was higher than or equal to the maximum grade ()!!! Cannot proceed with computation. And I haven't done anything but.
I continue.... here.
