Introduction to Randomization in TAO

TAO offers numerous possibilities for randomizing questions.

The choices within an interaction can be shuffled and so can the questions in the test. You can also configure a test to pick a random set of questions from a pool. Finally, it is possible to combine all three methods. They are all part of the QTI standard.

For our example, we created a set of about fifty items. They all share the same structure, asking for the capital of a country and offering three major cities as possible solutions. In this article, we will ignore the fact that the difficulty of these questions depends on many factors and assume they'd be of equal difficulty.
