[LON-CAPA-users] Reduced Points for multiple attempts

[Mills, Douglas G]

I have experimented with using a variable for the weight in the authored problem and then of course adjust that weight with each attempt. However, what I found was that the variable was not interpreted outside of the problem environment itself, so that looking at the student's results in the Assessment Chart, for example, did not reflect the changes to the weight variable within the problem.

Subject: [LON-CAPA-users] Reduced Points for multiple attempts

I have a faculty member that wants to give more points for first attempt, and reduce after that. We contacted Gerd and he gave us information on doing it in the Spreadsheet, but the issue is our grade sync to Blackboard Learn would ignore any of those calculations and only take the Awarded Points.

Is anyone doing anything where that can be handled within the problem itself?

See the faculty question below:

“After emailing Bob Herrick, and having Bob get Gerd's feedback, it sounds like deducting points based on attempts would need to be done after an exam has been submitted.  I'm guessing there would need to be a spreadsheet with each students attempts and score for each problem that would need to be run through a formula to adjust their score (1 attempt and correct = 1 point, 2 attempts and correct = 0.5 points, more than 2 attempts or incorrect = 0 points).  I would prefer to have a way to assign conditional points automatically, but I don't know if this is something that would need to be coded into each problem or something that we would need to code into LON-CAPA somewhere else, or if there would be a way to do this with BlackBoard when the scores get transferred.”
