Something that I find with using the "Review" button for quizzes, not all types of quiz questions will show the incorrect option.
I do not like the "Compliance" type of learning as it is not learning but just passing a set of questions because that is what we have to do.
In a piece of learning, using Storyline 3, we give the users a couple of tries when the question is a little more difficult than a true/false or multi choice question. If they get it incorrect the second time we either give them a hint or show them the answer as we are wanting them to learn rather than just get the correct answer.
Getting 100% is not the answer as we can teach people how to answer quiz questions without even knowing the content. Or, they can have the answers from someone else so they can get through the compliance exercise to please management but is that right?
Learning and being responsible for our own learning is more important than getting 100% in a Quiz.
Making a course interesting, getting staff to think and actually learn something is so important.
