manually grading assignments within the jupyter notebook with nbgrader

[jdchristensen]

I'll be teaching a course using CoCalc, and while I plan to use the autograder to give feedback on simple tasks, most of the time I expect to use manually grading, since I also want to grade on style, efficiency, documentation, etc. The current interface for manual grading seems to require the grader to flip back and forth between the student's notebook and the assignments tab, in order to enter grades in the assignments tab. It would be really nice if each manually graded question had a "grading" cell in which the grader could enter comments as well as the mark for that question. The grading cells could be strongly highlighted, so students can quickly scroll through and find them. These cells could be added by the run of nbgrader, which produces a file NAME_autograded.ipynb. I guess there would then have to be another stage where the manual grading was read in.

I haven't seen how manual grading works with the non-CoCalc version of nbgrader, but it could be a good model to follow.
