Moodle 2.0

Adding Interaction with Lessons and Assignments
Notice that selecting this option displays the number of points that the
student could have earned for the pages that , depending on the value of
this setting viewed so far.
If a lesson is not linear-that is, if it branches-then the path that each student takes
through the lesson can change. This means that each student can have the chance
to earn a different number of points. So in a branching lesson, the "total number of
points possible for the entire lesson" is not meaningful because the lesson can be
different for different students. For example, you might create a lesson with many
branches and pages, and then, require the student to earn at least 200 points on that
lesson. This would encourage the student to explore the lesson and try different
branches until (s)he has earned the required points.
Flow control
Some of the options under Flow control make the lesson behave more like a flash
card deck. Other settings on this page become irrelevant when a lesson is used for
flash cards.
Allowing student review: Allow student review allows a student to go backwards
in a lesson, and retry questions that (s)he got wrong. This differs from just using the
Back button on the browser, in that the setting enables the student to retry questions,
whereas using the Back button does not.
In the preceding screenshot, look at the setting for Action after correct answer.
Notice that in this case it is set to Show an unanswered Page. That means that after
a student answers a question correctly, Moodle will display a page that the student
either hasn't seen or that (s)he answered incorrectly. The Show an unanswered Page
setting is usually used during a flash card lesson to give the student second chances
at answering questions correctly. During a practice lesson, you will usually use
Allow student review to allow students to go back to questions that they got wrong.
