Abstract
An intelligent tutoring system can be implemented using filters, predictive modeling, and a knowledge warehouse, which allows content to be dynamically selected for individualized presentation to a learner. Such an intelligent tutoring system can be implemented using a variety of techniques, including polynomial vector equations in modeling, extensible markup language storage formats for presentation data, and a knowledge warehouse with information stored in data cubes.
