Gaze tutor: A gaze-reactive intelligent tutoring system

We developed an intelligent tutoring system (ITS) that aims to promote engagement and learning by dynamically detecting and responding to students' boredom and disengagement. The tutor uses a commercial eye tracker to monitor a student's gaze patterns and identify when the student is bored, disengaged, or is zoning out. The tutor then attempts to reengage the student with dialog moves that direct the student to reorient his or her attentional patterns towards the animated pedagogical agent embodying the tutor. We evaluated the efficacy of the gaze-reactive tutor in promoting learning, motivation, and engagement in a controlled experiment where 48 students were tutored on four biology topics with both gaze-reactive and non-gaze-reactive (control condition) versions of the tutor. The results indicated that: (a) gaze-sensitive dialogs were successful in dynamically reorienting students’ attentional patterns to the important areas of the interface, (b) gaze-reactivity was effective in promoting learning gains for questions that required deep reasoning, (c) gaze-reactivity had minimal impact on students’ state motivation and on self-reported engagement, and (d) individual differences in scholastic aptitude moderated the impact of gaze-reactivity on overall learning gains. We discuss the implications of our findings, limitations, future work, and consider the possibility of using gaze-reactive ITSs in classrooms.

An approach to developing computational supports for reciprocal tutoring

This study presents a novel approach to developing computational supports for reciprocal tutoring. Reciprocal tutoring is a collaborative learning activity, where two participants take turns to play the role of a tutor and a tutee. The computational supports include scaffolding tools for the tutor, and a computer-simulated virtual participant. The approach, including system architecture, implementations of scaffolding tools for the tutor and of a virtual participant is presented herein. Furthermore, a system for reciprocal tutoring is implemented as an example of the approach.

Teaching robots to cooperate with humans in dynamic manipulation tasks based on multi-modal human-in-the-loop approach

We propose an approach to efficiently teach robots how to perform dynamic manipulation tasks in cooperation with a human partner. The approach utilises human sensorimotor learning ability where the human tutor controls the robot through a multi-modal interface to make it perform the desired task. During the tutoring, the robot simultaneously learns the action policy of the tutor and through time gains full autonomy. We demonstrate our approach by an experiment where we taught a robot how to perform a wood sawing task with a human partner using a two-person cross-cut saw. The challenge of this experiment is that it requires precise coordination of the robot’s motion and compliance according to the partner’s actions. To transfer the sawing skill from the tutor to the robot we used Locally Weighted Regression for trajectory generalisation, and adaptive oscillators for adaptation of the robot to the partner’s motion.

Computer tutors can reduce student errors and promote solution efficiency for complex engineering problems

An ability to solve complex problems, for which a variety of solution paths are possible, is an important goal in engineering education. While feedback is critical to learning, hand grading of homework rarely provides effective, timely feedback on attempts to solve complex problems. Such feedback is also unfeasible in distance education contexts. A technology, based on the approach of cognitive tutors, is presented as a generally applicable method of providing automated feedback on complex problem solving, with truss problems studied in engineering as an example. The tutor maintains a cognitive model of problem solving for this class of problems, and associates various solution steps with distinct skills or knowledge components. One can determine whether students learn individual skills by measuring the error rate as a function of practice. Prior work has shown that for many skills the error rate indeed decreases with practice. New insight into the tutor׳s effectiveness, pertaining to the efficiency of student solution paths, is presented in this paper. While no explicit feedback is given regarding solution efficiency, it is found that students using the tutor become more efficient with practice. Furthermore, more efficient paths are found to be associated with making fewer errors.
