This could be related to grading errors. If there's an "Error on Submit for Grading" on a user, it seems like it comes up with this problem. Not 100% confirmed though. Need a little more search
select STARTDATE,USEREID,SITEID FROM SAM_EVENTLOG_T where ERRORMSG = 'Error on Submit for Grading' order by STARTDATE DESC;
Has anyone seen an issue with Samigo where a single submission will
have multiple answers to the same question in Multiple Choice Single
Correct (all default settings)? This was discovered by noticing that
a student had an automated score that was higher than the question
value. For example, one student had 14 answers to the same question
worth 2 points and received 28 points for that question. We have
found several of these cases.
This has been reported by Seminole, Stanford, IU and others. This seems to only affect around .1% of tests, so it's
I've done some data mining and found that this issue has been around
since October 2010 and is showing up as late as last week. Here is a
sample of some data I found:
Institution 1: 678,000 answers and 2 were duplicated at least twice
Institution 2: 23,379,146 answers and 804 were duplicated at least twice
I am using the range in order for the query to actually finish.
We could just add a contraint for ASSESSMENTGRADINGID, PUBLISHEDANSWERID. However this could have negative affects on the user experience.
