Encoding metaknowledge for historical databases

Historical knowledge is fundamentally uncertain. A given account of an historical event is typically based on a series of sources and on sequences of interpretation and reasoning based on these sources. Generally, the product of this historical research ta ...

Understanding Collaborative Program Comprehension: Interlacing Gaze and Dialogues

Marc-Antoine Nüssli, Pierre Dillenbourg, Patrick Jermann, Kshitij Sharma

We study the interaction of the participants in a pair program comprehension task across different time scales in a dual eye-tracking setup. We identify four layers of interaction episodes at different time scales. Each layer spans across the whole interac ...

Effects of sharing text selections on gaze recurrence and interaction quality in a pair programming task

Marc-Antoine Nüssli, Patrick Jermann

We present experimental findings from a dual eye-tracking study that illustrate the effect of different ways of sharing se- lection in remote pair-programming scenario. Forty pairs of engineering students had to complete several program under- standing tas ...

Dual Eye-Tracking Methods for the Study of Remote Collaborative Problem Solving

Marc-Antoine Nüssli

Applied eye-tracking has been extensively used for the study of psychological processes. More recently, some researchers have used this technique to study the interaction between people by tracking and analyzing eye-movements of two persons synchronously. ...

Facilitating peer knowledge modeling: Effects of a knowledge awareness tool on collaborative learning outcomes and processes

Mirweis Sangin, Marc-Antoine Nüssli, Pierre Dillenbourg

We report an empirical study where we investigated the effects, on the collaborative outcomes and processes, of a cognition-related awareness tool providing learners with cues about their peer’s level of prior knowledge. Sixty-four university students part ...

Collaborative Gaze Footprints: Correlates of Interaction Quality

Marc-Antoine Nüssli, Pierre Dillenbourg, Patrick Jermann

Dual eye tracking offers new possibilities for the analysis and diagnosis of collaborative interaction. Cross-recurrence analyses and visualizations offer insight into how closely two collaborators’ gaze follow each other. We contrast two cases to illustra ...

Using dual eye-tracking to unveil coordination and expertise in collaborative Tetris

Marc-Antoine Nüssli, Patrick Jermann, Weifeng Li

The use of dual eye-tracking is investigated in a collabora- tive game setting. The automatic collection of information about partner’s gaze will eventually serve to build adaptive interfaces. Following this agenda, and in order to identify stable gaze pat ...

Gaze quality assisted automatic recognition of social contexts in collaborative Tetris

Marc-Antoine Nüssli, Patrick Jermann, Weifeng Li

The use of dual eye-tracking is investigated in a collabora- tive game setting. Social context influences individual gaze and action during a collaborative Tetris game: results show that experts as well as novices adapt their playing style when interacting ...

Collaboration and abstract representations: towards predictive models based on raw speech and eye-tracking data

Mirweis Sangin, Marc-Antoine Nüssli, Pierre Dillenbourg, Patrick Jermann

This study aims to explore the possibility of using machine learning techniques to build predictive models of performance in collaborative induction tasks. More specifically, we explored how signal-level data, like eye-gaze data and raw speech may be used ...

Knowledge interdependence with the partner, accuracy of mutual knowledge model and computer-supported collaborative learning

Mirweis Sangin, Marc-Antoine Nüssli, Pierre Dillenbourg, Gaëlle Molinari

The present study is part of a project aiming at empirically investigating the process of modeling the partner’s knowledge (Mutual Knowledge Modeling or MKM) in Computer-Supported Collaborative Learning (CSCL) settings. In this study, a macro-collaborative ...

When Co-Learners Work on Complementary Texts: Effects on Outcome Convergence

Mirweis Sangin, Marc-Antoine Nüssli, Pierre Dillenbourg, Gaëlle Molinari

In this paper, we examined the effect of knowledge interdependence among co-learners on knowledge convergence outcomes. Prior to collaboration, two partners read the same text in the independent condition while each of them read one of two complementary te ...
