Abstract

This article applies machine-learning techniques to student modeling, presenting a method for discovering high-level student behaviors from a very large set of low-level traces corresponding to problem-solving actions in a learning environment. The system encodes basic actions into sets of domain-dependent attribute-value patterns. Then, a domain-independent hierarchical clustering identifies high-level abilities, yielding natural-language diagnoses for teachers. The method can be applied to individual students or to entire groups, such as a class. The system was applied to the actions of thousands of students in the domain of algebraic transformations. This article is part of a special issue on intelligent educational systems.
