Sorry if this has already been asked, I did try a search.
Is it possible to set a question to have multiple true/false statements?
Having thought about it, this would generalise out to a kind of question grid or table. This is fairly common in satisfaction type questionnaires where a set of questions all with the same (multiple choice) answers are down the left and the answers are along the top, the radio buttons forming the rest of the grid. True/False would just be a special case of this.
An interesting development project...
viz:
A1 A2 A3 A4
Q1 o o o o
Q2 o o o o
Q3 o o o o
Q4 o o o o
(the o's are meant to be the check boxes).
If I have five options available and three need to be ticked (ie: they apply to the statement, or question), then each correct answer gets 33.3% and each incorrect answer gets -50%. this means that if all the options are ticked, the student gets 0. It can mean that the student ends up with -100%, but then they would have to completely misunderstand the question.

I have used multi multiple choice for about a quarter of my quiz questions over the last term, and have been rather frustrated with the current scoring method. For the student, each choice represents one decision that must be made. So it seems unfair that with four choices, sometimes selecting one wrong choice will result in a score of 0 (3 choices correct), and in other cases a score of 67% (1 choice correct).
The problem with current scoring in multi multiple-choice is that credit is given only for selecting the correct responses. It needs to be revised so that credit is also given for not selecting the incorrect responses. Rather than assigning e.g., 33.3% for each of 3 correct choices and -100% for one wrong choice, it would make much more sense to assign each 25% and specify whether each choice is correct (true) or incorrect (false). Then each response receives its correct weight.
True, with this scenairo you have to guess very badly to get 0, but you have to guess very well to get 100%. Leaving all blank will typically give some positive score as will marking all the answers, but in regular multiple choice always marking "a" (or whatever) will also normally yield a positive score. The best prevention for credit with no response is the T-F-Don't Know method (defaults to Don't Know), since that requires a resonse to earn points.
I would really like to see multi multiple-choice scoring improved. The old scoring method could be left as a default option, e.g., by setting a "score as TF choices" radio button above the list of answers. If selected, each answer is given equal weight automatically according to whether it is designated Correct or Incorrect (or T/F). Displaying a "Don't Know" could also be an option. Implementing a Multiple True/False would also work, since conceptually there isn't a great difference between multi multiple choice and a single stem followed by several T-F responses. So I would welcome a solution either way -- revised multi multiple-choice scoring or multiple T/F, whichever is easier to implement (and add to GIFT).

Very intriguing. I would love to try it, but I don't see any way to do it in Moodle at present. You might want to request it as a feature addition in the bug tracker (don't know what the guidelines are for that). Anyone else interested in this capability?
Aslo, is there any data on how this affects students with severe test anxiety? I would expect it might exacerbate the problem, but that's just an initial hunch.
