The Help
In 2011, Koedinger, and his colleagues Ido Roll, Vincent Aleven and Bruce McLaren introduced the Help Tutor, an enhanced version of the Geometry Cognitive Tutor that is capable of giving immediate metacognitive feedback on students' help-seeking errors. As an enhanced version, the Help Tutor teaches help-seeking skills by giving metacognitive feedback on students' help-seeking errors in the context of learning a domain-specific problem-solving skill. The Help Tutor messages include only domain-independent metacognitive content for several reasons: to encourage students to focus more on the metacognitive feedback (and not be distracted by domain content), to help students generalize the help-seeking skills, and to make the Help Tutor reusable with different Cognitive Tutors.
