Scenario Questions- Non-technical

I created the 3C scenario model years ago to help my novice instructional designers step away from content dumping.

Challenge: what does the learner know; how can you challenge their understanding?

Choices: it's a course so you need to create an environment where they can make decisions, thus you need to present some choices

Consequences: what happens when they make a decision? 

I think the essence of a scenario is to simulate the types of decisions/actions you want the learner to make and to use that as a means to assess their level of understanding. And at that point you can direct them to the appropriate types of feedback. Perhaps the feedback is literal corrective feedback or it could be that it pushes them into a consequence where they need to make additional decisions as the result of the previous decision.

There's no rule on how complicated it needs to be. I think the rule is how well it challenges the learner's understanding and lets them demonstrate what they know. They can be a simple scenario like yours or you can make it much more complex.
