scoring multiple

Added by Machon Chen over 8 years ago

I have tried the following:

**[horiz,name=M_wrong] Question multiple choice with scoring
+{b=2,m=-1} Correct_1
-{b=1,m=-1} Wrong_1
+{b=1,m=-0} Correct_2
-{b=1,m=-0} Wrong_3

and ticked Correct_1 and Wrong_1
I get the result 0/3 but I would expect 1/3 or maybe I do not understand how to do this?
(I would like to give more marks to some answers and not take of points for not answering some correct answers.)

Best regards

Scores for each answer:
  1. Correct_1 is ticked, so the answer is correct, so score=2
  2. Wrong_1 is ticked, so answer is wrong, so score=-1
  3. Correct_2 is not ticked, so answer is wrong, so score=0
  4. Wrong_3 is not ticked, so answer is correct, so score=1

Student score for this question: 2/5

The problem here is that the default value for DefaultScoringM is haut=2, which interferes with your scoring. You have to cancel this default value with

DefaultScoringM: 

I must admit this is quite confusing and has to be changed...

Other way to cancel the effect of the default scoring for the question: declare any scoring for the question itself. For example:

**[horiz,name=Mwrong]{empty} Question multiple choice with scoring
+{b=2,m=-1} Correct_1
-{b=1,m=-1} Wrong_1
+{b=1,m=-0} Correct_2
-{b=1,m=-0} Wrong_3

Here the empty scoring has no special effect, but cancels the haut=2 default scoring.

Thank you.

You do not have to change but I think that there should be a lengthier chapter in the documentation with lots of examples how scoring is working especially for the multiple questions.
