This paper investigates the use of conversational agents to scaffold on-line collaborative learning discussions through an approach called Academically Productive Talk (APT). In contrast to past work on dynamic support for collaborative learning, where agents were used to elevate conceptual depth by leading students through directed lines of reasoning(More)
Detailed analysis of face to face computer mediated interactions implies a study of a corpus composed of the interaction traces produced by the collaborative tool and video and audio recordings. Because of their separate nature, it is frequently difficult to perform this joint analysis. In order to facilitate such analyses we propose a model for describing(More)
The analysis of multimodal computer-mediated human interaction data is difficult: the diverse nature of this data and its sheer quantity is challenging enough, but a further obstacle is introduced by the complex nature of these interactions. In this paper, we describe the kinds of activities performed by researchers wishing to analyze this data. We present(More)

In this paper, we explore using an intelligent dialogue tutor to influence student academic self-efficacy, as well as its interaction with group self-efficacy composition in a dyadic learning environment. We find providing additional tutor prompts encouraging to students to participate in discussion may have unexpected negative effects on self-efficacy,(More)
Temporality and the unfolding of collaborative processes over time are an important aspect in understanding the underlying mechanisms of collaborative learning. In this paper, we describe how interactive sliding window visualizations can integrate with existing methodologies to provide new insight into how interactions develop over time. We illustrate the(More)
