In addition to traditional random blocks, Blackboard 9.1 now includes question sets for utilizing randomized pools of questions.  What is the difference between a question set and a random block?  Random blocks pull questions at random from an entire pool, with no customization available to select which questions from the pool to include or exclude.  Question sets allow instructors to tailor which specific questions to use for the random block.

For example, if a pool contains 5 questions on aphasia and 5 questions on apraxia and you would like students to receive one randomly-selected question on each topic, a random block cannot be used to achieve this.  Because random blocks pull questions without discrimination from a pool, it is possible that one student could receive two questions on aphasia, another could receive two on apraxia, and another yet might receive the desired one of each.  With a question set, you can specify which questions to draw from, based on individual selection, keyword, or level of difficulty.
