Suppose your Lesson structure is completely linear; that is, it does not contain any branches. It consists of an explanation, followed by some questions, followed by additional explanation, followed by more questions, etc. You can can use a quiz to simulate this structure as follows:
MCQ
MCQ
MCQ
Description question (explanation part II)
MCQ
MCQ
Description question (explanation part III)
MCQ
MCQ
A disadvantage of this technique is that the movement of students through the lesson cannot be controlled. For example, the student can jump to the material in the second part of the lesson without first having mastered the material in the first part.
An advantage is that we leverage our investment in a question database (probably only significant to people with large question databases).
Incidentally, commercial products like LessonBuilder create lessons with similar linear structure and lack of control, so I guess it's fair to call them "lessons" with a small L.
Has anyone else used this idea? If so, do you have any additional thoughts or suggestions?
