Are Pedagogical Agents' External Regulation Effective in Fostering Learning with Intelligent Tutoring Systems?

INTELLIGENT TUTORING SYSTEMS, ITS 2016, Vol. 9684, pp. 197–207.

By: R. Azevedo n, S. Martin n, M. Taub n, N. Mudrick n, G. Millar n & J. Grafsgaard n

author keywords: Self-regulated learning; Metacognition; Pedagogical agents; Externally regulated learning; ITS; Scaffolding; Learning; Product data; Process data
TL;DR: Testing whether external regulation provided by artificial pedagogical agents PAs was effective in facilitating learners' self-regulated learning SRL and can therefore foster complex learning with a hypermedia-based intelligent tutoring system indicated that those in the AS condition gained significantly more knowledge about the science topic thanThose in the C condition.

2016 journal article

Do You Think You Can? The Influence of Student Self-Efficacy on the Effectiveness of Tutorial Dialogue for Computer Science

International Journal of Artificial Intelligence in Education, 27(1), 130–153.

By: J. Wiggins n, J. Grafsgaard n, K. Boyer *, E. Wiebe n  & J. Lester n

author keywords: Self-efficacy; Tutorial dialogue; Computer science education
TL;DR: This article examines a corpus of effective human tutoring for computer science to discover the extent to which considering self-efficacy as measured within a pre-survey, coupled with dialogue and task events during tutoring, improves models that predict the student's self-reported frustration and learning gains after tutoring.

2016 article

Predicting Learning from Student Affective Response to Tutor Questions

INTELLIGENT TUTORING SYSTEMS, ITS 2016, Vol. 9684, pp. 154–164.

By: A. Vail n, J. Grafsgaard n, K. Boyer *, E. Wiebe n  & J. Lester n

TL;DR: This work examines student facial expression, electrodermal activity, posture, and gesture immediately following inference questions posed by human tutors and shows that for human-human task-oriented tutorial dialogue, facial expression and skin conductance response following tutor inference questions are highly predictive of student learning gains.

2013 article

Automatically Recognizing Facial Indicators of Frustration: A Learning-Centric Analysis

2013 HUMAINE ASSOCIATION CONFERENCE ON AFFECTIVE COMPUTING AND INTELLIGENT INTERACTION (ACII), pp. 159–165.

By: J. Grafsgaard n, J. Wiggins n, K. Boyer n, E. Wiebe n  & J. Lester n

author keywords: affect; frustration; learning; computer-mediated tutoring; facial expression recognition; facial action units; intensity
TL;DR: A study to analyze a video corpus of computer-mediated human tutoring using an automated facial expression recognition tool that detects fine-grained facial movements reveals three significant relationships between facial expression, frustration, and learning. (via Semantic Scholar)

2012 conference paper

Multimodal analysis of the implicit affective channel in computer-mediated textual communication

ICMI '12: Proceedings of the ACM International Conference on Multimodal Interaction, 145–152.

By: J. Grafsgaard n, R. Fulton n, K. Boyer n, E. Wiebe  n & J. Lester n

TL;DR: Computer-mediated tutoring sessions were recorded with Kinect video and depth images and processed with novel tracking techniques for posture and hand-to-face gestures and it was demonstrated that tutors implicitly perceived students' focused attention, physical demand, and frustration.
