All of these processes help accommodate all students to an environment that is more conducive to learning. The second benefit of these types of learning tools is for the educators. Resources otherwise not available to the student can be simulated in the classroom using computers. For example, a teacher can show how a hydrogen reactor would work from the inside. Not a good field trip to take, but an excellent way to demonstrate inter-atomic reactions.
Educators save enormous amounts of prep time when using things like test generators.
Time usually spent on making a test can be spent on other types of curriculum enhancements. Some test generators can fill in a test using a given question bank, but when there are not enough questions to fill a test on a specific subject, they rely on user interaction to complete the test. The idea of an automatic test generator that uses rough set theory stemmed from a project that one of my professors was working on. With rough set theory, one can utilize more information from relational databases by being able to include certain relevant information that might not be an exact match for a given query. R is the equivalence class lower bound.
