[LON-CAPA-users] another instance of correct answer apparently being unaccepted...

[Mills, Douglas G]

Hi All,

I've amassed as much data as I know how to amass on this situation which has occurred now with a different student. Here's what I have:

Looking at his "scores per problem" view via the Course Progress interface, it appears that he has credit for all 15 questions:
https://uofi.box.com/s/cn7vrpqyenp1zr7owke9

Clicking on the links to view his actual submissions, however, indicates that question 15 is currently wrong. Here's a screenshot of that with the previous tries dialogue up where you can see that his second attempt was graded as CORRECT:

Here I scroll down the page and look at his submissions for this part. I see an incorrect submission, what appears to be a non-submission — the date and time are there but no other details, the submission judged as "exact_ans" and then one evaluated ad "incorrect."  Note also that these two latter submissions are both listed as Trial: 2. Then there are several more "non-submissions" -- dates are there, but no other information.   Not in the screen shot there are a couple other parts submitted next, then several more of these non-submissions:

And finally here is where I click as if to manually assign grades to this student.  Part 41 is the part in question. You see here that it shows part 41 as currently being awarded 1 point (if I understand that correctly) but NOT having the red checkmark next to it under weight.  Thinking perhaps I can override, I went ahead and saved this as if I had awarded 1 point but that did not change anything when I came back to the student.

This is especially irksome because it has occurred on our prelab0 and Safety quiz which is has to be completed before anything else in the course can be accessed. The student is stuck, I think as represented by all the "non-submissions" now showing . I 'll next try resetting the problem and hopefully he can then successfully complete it, but I wanted to document what we're seeing here first. Any thoughts?  Is there somewhere I should be pulling a more thorough report of what has transpired from?
