Quiz

I think someone has a project submission to Moodle Users Association for a late penalty, which I think belongs in the gradebook, not the individual activity.  That way it can be applied anywhere.  

The other three would be nice to see in the quiz though.  I know there have been several requests for a breakdown by category or section.  

I agree that that a behaviour plugin is not the right way to do this, but is the best I could do at addressing my current need. It is at best a feature prototype to evaluate the utility of the function.

It would be great to have a new plugin type to address this and the other situations. The behaviour plugins have limitations because they do not have acesss to quiz settings. This is why it requires manually changing the behaviour and using penalty setting in the question. It is unclear how a new plugin type would handle multiple submissions in adaptive mode. It seems like it would still need to go by quiz start or end time.

We are just talking about this at the #mootieuk16 hackfest. Just adding some notes here, so everything is in this thread.

Some other things that could be handled by this proposed plugin type:

• Penalty if you use more than one attempt. (E.g. final score is the higher out of 'score on attempt 1' or 'score on attempt 2 less 20%'.)
• So, actually, this plugin type could be used to replace the existing hard-coded logic for Final grade = first/last/best/average grade, which would clean up the code.

There was some talk about whether this could be a more general plugin type. Several of the same score modification rules would also make sense for the Assignment tool. Should we find a way to let the code be shared? Perhaps it belongs in the gradebook?

Note that there did not seem to be an existing tracker issue for "Different scores by section", but someone just created MDL-53639, which I have edited a bit, to use for that. Does not make it any easier to code, unfortunately.

Hi Nadav,

What you are doing seems more like a type of aggregation than a question behaviour.

I think Tim has suggested adding a new plugin type either to the quiz or gradebook that would have the information to do this calculation without having to sift through the database. It would be a more elegant way of doing it.

I reworked the way this plugin behaves a little because I was have difficulty with making the calendar events sensible to students. Instead of having a penalty phase before the due date, it now sets a grace period after the original close where students can attempt the quiz with a less favorable question behaviour. The original close date shows in the calendar, but the final close of the grace period does not.

If a new grading plugin type is added, consideration should be given to reworking the calendar events in the quiz. The code for start and stop events and overrides is currently contained  in the quiz library rather than access type plugins. The code in quiz_update_events deletes all other calendar events associated with the quiz. The grading plugins ought to have the capacity to add other due dates.
