Quiz versus completion

My opinions only.

If the module is compulsory, and you are only concerned that they proceed through it end-to-end, then make it as interactive as possible; otherwise you are only frustrating the learners. 

Including a quiz that evaluates content understanding is a good idea. Making that comprehensive of all 10 segments is also a good idea - if the learners know that up front, and have access to all of the modules so they can review the information while taking the quiz. I presume you are not creating some type of advancement exam that requires full memorization in order to pass successfully, so treat your learners as you would like to be treated, and how you probably work: when you don't know the answer, you go search for it...

If it is compulsory, and you need to track performance on all segments, then you will need some type of quiz or measurement. I would suggest that you build a question bank that has 3-5 questions for each of the 10 segments; then at the end, create a draw that pulls two questions from each segment, and make it an "80% pass" score to receive credit for the course.

The 80% score is an acceptable standard in nearly every adult learning context that I know of. There is likely research (available in ERIC?) that was done well over 30 years ago that supports this position.

But as long as you are only concerned about sequential completion, then please make it as interactive as you can. The attention span you save may be your own. (-:
