[Building Sakai] Assignment submission issue

[Geng, Kelly]

Zhen,

I got an another incident today which seems similar in nature to the last one: in grading an assignment, the instructor saw 2 exactly  same submissions of 2 students next to each other on the roster. She graded both submissions and returned the grades(0 for both) thinking that they are plagiarism, but the students were shocked and denied vehemently. So she reported this issue to see whether it was a system error (or something else).

When I looked at the submissions table, there is only 1 submission with a "submit date" and the "submitted text" in the xml file, but both have the same submitted text in the "feedback text" field. It seems like only 1 student submitted the work, but somehow the text got copied to the other student's 'feedback text'. But I can't see what can possibly cause this. Now this (one student's submission gets copied to another student) has happened to 2 instructors, can you think of any scenario to lead to this? I attached both student's submission xml for your reference.

Thanks,
Kelly

Kelly:

Based on the xml file, the feedbacktext and feedbacktext-html fields are somehow empty, while the submittedtext and submittedtext-html still contain the original student submission.

The feedbacktext defaults to be student submitted text at first. However, instructor can add inline feedback text there and hence rewrite it. Maybe during the grading period, instructor accidentally cleared the feedback text field, and then released the grading to student?

You can use the "Download All" feature in instructor grading view to get the original student submitted text, and let instructor paste it(along with his feedbacks) into the feedback text area to "restore" the student submission materials.

Thanks,

- Zhen

Zhen,

We are running 2.7.x.  I was able to verify that the submitted text is not showing(blank) in both instructor and the student's view.

I was able to decode the submitted text successfully. The student already sent her saved copy to the instructor for grading but didn't try to submit it again.

Hi, Kelly:

What version of Sakai are you running?

I did see the student submission text included in the xml file. You can use Base64 decoder to view the original text, e.g. use this url: http://www.opinionatedgeek.com/dotnet/tools/base64decode/

Can you login as the instructor and verify the problem?

Thanks,

- Zhen

Zhen,

We have a faculty who claims that she was reading a student's in-line submission when it changes to another student's(the student right next in the roster) submission somehow. And after she logged out and back in, the original student's submission disappeared. I looked into the assignment_submission table and found the submission as attached. It seems to me there WAS submitted-text recorded. Can you shed some light on this?

Thanks,
Kelly
