The question authoring for the question types in Lesson would have one more step: a page for defining the jumps.
So, when selecting a question to add to the Lesson, one would be presented with the course question bank. One would then select a question to add to the Lesson. The next page would define the possible jumps from that question. This would keep Lesson's unique navigation intact. (Open to suggestions for streamlining this process!)
The question types display.html templates will allow for Lesson to customize the look of any or all of the questions, which upon reflection, I think is necessary. Lesson question pages tend to have more content and so the formatting needs to handle this gracefully.
So, both formatting and navigation will still be unique to Lesson (among other Lesson features
) and thus make it a viable alternative to Quiz.Cheers,
