Hi! I'm trying to set up a quiz for an assignment that was on paper in a previous incarnation. The assignment is for a music theory class.
For one of the questions, I'd like students to identify all of the different pitches in a given passage. I would like to set this up like a multiple choice question in which students select certain pitches out of the full collection of twelve.
In other words, the possible answers (separated by commas) are:
C, C#/Db, D, D#/Eb, E, F, F#/Gb, G, G#/Ab, A, A#/Bb, B
The answer to the question might be something like:
C, D, E, F, G, A, B
In this case, I would want students to select all seven correct answers for full credit. I would also like them to be penalized for selecting incorrect options (to avoid the potential for them to exploit the system by simply selecting all of the options).
I know this sort of thing can be done with the multiple choice question type, but here's the problem. Since there are seven equally-correct answers, each one should be worth approximately 14.29% (100/7) of the grade for that question. (The penalty for the five wrong answers in this case is more straightforward: 100/5 = 20.)
Is there any way around the set values for multiple choice options? I've seen other posts asking if multianswer questions like this are possible in cloze (here), but I'm wondering if anyone has ideas about how I can do this. Right now it looks like the best solution is to simply format the question as an essay and grade it manually.
