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

[Harding, Gene L]

Hi Stuart,

I cannot find the lenient and retrypartial parameters.  Are they new to v2.11?

Thanks,
Gene

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).
