Assessment not working as intended

A quick thought (OK, only one cup of coffee so far) - instead of giving an option to review the entire quiz, why not set the questions up so that you have the learners immediately review the incorrect answers?

Here's what we did - Would this approach work for you?

This is one slide out of a question bank. The course deals with working safely (outdoors) in extreme heat (I'm in Arizona).

You can see the correct answers (checks), and the three layers: Correct, Incorrect, and Explanation.

When the learner gets the question wrong, this is the "Incorrect" layer:

And here is the Explanation layer:

Essentially, we copy and paste the relevant slide content that specifically addresses the objective/question that is measured here. 

So like your learners, ours have to pass with an 80% score, and they get two tries on the quiz before having to repeat the entire course. We have seen a noticeable drop in the number of learners who do not pass even after two attempts, and the LMS team has far fewer complaints about "having to take this class again."

What do you think?
