In this study, we investigate how pre-service teachers' group dialogues emerged and intersected across time and space as students collaboratively constructed a video-based mind map to prepare for oral exams in a pedagogy course. The study was conducted as part of a design-based research project investigating the ways that video-based mind maps can…

This research investigates a design and development approach to improving science teachers' access to effective professional development (PD) in a fully online, asynchronous environment. Working with a small number of teachers, this study explores how a design combining social capital mechanisms with essential teacher learning and PD…

This paper presents a study of group cohesion as it arises in online small group different time and place collaboration. Cohesion is modeled in terms of the extent to which a group makes progress together through contentful and meaningful collaborative interactions. This paper makes the case that cohesion in a small group working collaboratively…

This paper explores the emergence of joint problem solving in online environments where the participants work together but at different times and from different places. Collaborations of this sort have been referred to as loosely coupled collaborations. The focus is on "venue" which is the virtual substitute for physical copresence under…

Collaboration scripts have repeatedly been implemented in Computer-Supported Collaborative Learning (CSCL) to facilitate collaboration processes and individual learning. However, finding the right degree of structure is a subtle design task: scripts that are too rigid may impair self-regulation and hinder learning; scripts that are too flexible…

The goal of this study was to develop a classification for a range of discourse patterns that occur in text-based asynchronous discussion forums, and that can aid in the distinction of three modes of discourse: knowledge sharing, knowledge construction, and knowledge building. The dataset was taken from Knowledge Forum® databases in the Knowledge…
