One of the problems with a multiple choice question you've added to a Captivate quiz is the all or nothing aspect of the question. It is possible to setup some questions that allow for multiple correct answers. It would be nice if you could award partial credit should the learner select some, but not all, of the correct answers.
Say hello to the Partial Score feature available in Adobe Captivate 6 and 7.
In the two images below, I have inserted a Multiple Choice question into my project. From the General group of the Quiz Properties panel, I set the number of Answers to 4.
From the General group of the Quiz Properties panel, I next selected Multiple Answers. Then, on the slide, I selected two of the answers as correct answers.
To allow a learner to get partial credit, I accessed the General group on the Quiz Properties panel and then selected Partial Score.
The final step in allowing for partial scores is the trickiest. You need to determine how many points each correct answer is worth. Having selected Partial Score on the Quiz Properties panel, one would assume that an option would magically appear near Partial Score that would allow for specific scores to be assigned to each answer. That's not how it works at all. First, you need to select one of the correct answers. Then, on the Properties panel (not the Quiz Properties panel), expand the Advanced Answer Option group. Then you need to assign a point value to the selected answer.
You would repeat this step for each correct answer (the total points assigned to each answer cannot be greater than the point value assigned to the question).
In the question slide that I used for this example, the question was worth 10 points. I assigned 5 points to each correct answer. If a learner selected one of the two correct answers, they would be awarded 5 points out of the possible 10.
