There are two ways to set up random branching in a decision structure. You can have Authorware select any path at random, regardless of whether it's selected the path before, or you can have Authorware select randomly only from the paths it hasn't yet taken.
For example, you could set up the pretest described in the previous procedure so that Authorware selects randomly from the questions it hasn't yet presented a user. Everything else about the decision structure would be the same except that you'd select Randomly To Unused Path rather than Sequentially as the Branch option.
Randomly To Unused Path also comes in handy if you need to test a student a second time on the same material. You'd set up each question so that it has two or more versions, depending on the number of times a student is allowed to retake the test.
If you leave Reset Path On Entry deselected, Authorware remembers which version of the question it has already presented. The next time it passes through the decision structure, it presents a different version.
