Given the important role that meta-cognitive processes play in learning,
intelligent tutoring systems should not only provide domain-specific assistance, but
should also aim to help students in acquiring meta-cognitive skills. As a step toward this
goal, we have constructed a Help Tutor, aimed at improving students’ help-seeking
skill. The Help Tutor is based on a cognitive model of students’ desired help-seeking
processes, as they work with a Cognitive Tutor (Aleven et al., 2004). To provide metacognitive
tutoring in conjunction with cognitive tutoring, we designed an architecture in
which the Help Tutor and a Cognitive Tutor function as independent agents, to facilitate
re-use of the Help Tutor. Pilot tests with four students showed that students improved
their help-seeking behavior significantly while working with the Help Tutor. The
improvement could not be attributed to their becoming more familiar with the domainspecific
skills being taught by the tutor. Although students reported afterwards that they
welcomed feedback on their help-seeking behavior, they seemed less fond of it when
actually advised to act differently while working. We discuss our plans for an
experiment to evaluate the impact of the Help Tutor on students’ help-seeking behavior
and learning, including future learning, after their work with the Help Tutor.
