Abstract

Ambiguity is a well-known problem in student modelling, and in user modelling in general. In this paper we present the results of an experiment in the domain of German adjectives. We trialled a modified student interface that gathers more data during problem solving by requiring the student to perform a related subtask. There is evidence that the students who performed the subtask outperformed the control group on a post-test despite the extra task slowing them down, suggesting the extra effort required by the students to overcome ambiguity was worth the intervention.
