[LON-CAPA-users] LON-CAPA-users Digest, Vol 81, Issue 2

At one point I tried something like this within the problem itself through the wonderful features of Lon-Capa giving access to so much information, such as the number of tries, etc. but I think where I fell short was the fact(? -- please correct me if I'm wrong here!) that you can only use the ASSIGNED_SCORE option with CustomResponses. While I could inside the problem calculate the grade I wanted based on number of tries, and tried to use the weight parameter to make that the grade, it seems that my carefully calculated weight variable did not make it to wherever the grades are stored and the part ended up with the default weight rather than the value I had calculated.

    The problem we run into with using the spreadsheet is that the grade sync to Blackboard won't take anything that is calculated in there, it only pulls the awarded total.

    What if you could get the tries and awarddetails info back from the radiobuttonresponse.pm, then do something that multiples by the awarddetails based on number of tries?

    I have no idea how to code that, but just thinking logically.

    The only ways I know how to do this are via CustomResponse as it sounds like you're already doing OR using the Lon-Capa gradebook, which we have experimented with a bit but have not sustained.  It's powerful but challenging to get used to I think is a fair statement.  There are no doubt others on the list though who have mastered the gradebook and use it to great advantage who can hopefully contribute guidance if you'd like to explore that direction.

    Subject: [LON-CAPA-users] Partial Credit for multiple tries

    I have a faculty member that wants to implement the following:

    On a multiple choice question
    Correct in 1 attempt = 100% credit
    Correct in 2 attempts = 75% credit
    Correct in 3 attempts = 50% credit
    Incorrect = 0% credit

    We do something like this in Math, but on Customresponse questions and they use customgraders as well.

    Does anyone have an example of making this happen in just a simple M\C problem?

    I am decent at reverse engineering, but need a lead.

    Thanks
