[LON-CAPA-users] 2.11 partially correct and Lenient grading

[Stuart Raeburn]

Hi,

If you wish to allow students to continue to make submissions (up to  
the maximum number of tries allowed) for an optionresponse or  
matchresponse item, for which the "lenient" parameter has been set,  
then you would also want to set the "retrypartial" to "yes".  As you  
noted the default is "no".

Note: students may reduce their scores for the item as well as  
increase them, by making additional submission(s) after submitting a  
partially correct response, because LON-CAPA will report points  
awarded for a problem part based on the value of "awarded" computed  
for the most recent submission (at the time it was graded), unless  
overridden by a score entered via the grading interface by course  
personnel.

For the case where both lenient and retrypartial parameters are set to  
yes, no additional submissions are allowed for the student when all  
response items have been answered correctly (i.e., full credit has  
been awarded).

What matters is the value of the lenient parameter (as it applies to  
the particular student and the particular resource) when a submission  
is graded.

Any partially correct submissions to optionresponse or matchresponse  
submitted during a time when lenient is set to "default" (or not set)  
will receive an awarddetail of INCORRECT, and an awarded value of  
value 0 (unless bubblesheet grading).

By contrast, partially correct submissions will receive an awarddetail  
of ASSIGNED_SCORE and an awarded value of #right/#possible, when  
lenient is set to "yes".

There is no effect on previously graded submissions when  
changing/setting the lenient parameter after a homework is set has  
closed).
