Using Vector-Space Model in Adaptive Hypermedia for Learning

Although many of the existing adaptive learning environments use other approaches, the vector-space model for information retrieval can be used in providing individualized learning with hypermedia. A system employing a modified version of the vector-space model is described. The approach taken is tested in a real-life setting to evaluate and train basic arithmetics skills of learners in elementary education. Although the impact on learning was not measured, the approach provides a useful evaluational help for the teacher to make observations about the learning processes of the learners.
