Predicting Dialogue Breakdown in Conversational Pedagogical Agents with Multimodal LSTMs

ARTIFICIAL INTELLIGENCE IN EDUCATION, AIED 2019, PT II, Vol. 11626, pp. 195–200.

By: W. Min n , K. Park n, J. Wiggins*, B. Mott n, E. Wiebe n , K. Boyer*, J. Lester n

Contributors: W. Min n , K. Park n, J. Wiggins*, B. Mott n, E. Wiebe n , K. Boyer*, J. Lester n

author keywords: Conversational pedagogical agent; Multimodal; Dialogue breakdown detection; Natural language processing; Gaze
TL;DR: Results from a study with 92 middle school students demonstrate that multimodal long short-term memory network (LSTM)-based dialogue breakdown detectors incorporating eye gaze features achieve high predictive accuracies and recall rates, suggesting that multi-modal detectors can play an important role in designing conversational pedagogical agents that effectively engage students in dialogue.

Take the Initiative: Mixed Initiative Dialogue Policies for Pedagogical Agents in Game-Based Learning Environments

ARTIFICIAL INTELLIGENCE IN EDUCATION, AIED 2019, PT II, Vol. 11626, pp. 314–318.

By: J. Wiggins*, M. Kulkarni*, W. Min n , K. Boyer*, B. Mott n, E. Wiebe n , J. Lester n

Contributors: J. Wiggins*, M. Kulkarni*, W. Min n , K. Boyer*, B. Mott n, E. Wiebe n , J. Lester n

author keywords: Pedagogical agents; Game-based learning; Initiative
TL;DR: A study to investigate two different agent dialogue policies with regard to conversational initiative, a core consideration in dialogue system design found the Mixed Initiative policy better supported the goals of the game-based learning environment by fostering exploration, yielding better performance on in-game assessments, and creating higher student engagement.

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.

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)
