Social Network Analysis (SNA) has enabled researchers to understand and optimize the key dimensions of collaborative learning. A majority of SNA research has so far used static networks, i.e., aggregated networks that compile interactions without considering "when" certain activities or relationships occurred. Compressing a temporal…

In e-learning settings, the interactions of students with one another, with the course content and with the instructors generate a considerable amount of information that may be useful for understanding how people learn online. The objective of the present research was to use social network analysis to explore the social structure of an e-learning…

Analysing the structure of a social network can help us understand the key factors influencing interaction and collaboration in a virtual learning community (VLC). Here, we describe the mechanisms used in social network analysis (SNA) to analyse the social network structure of a VLC for teachers and discuss the relationship between face-to-face…

This paper presents the Massively Open Online Course for Educators (MOOC-Ed) network dataset. It entails information on two online communication networks resulting from two consecutive offerings of the MOOC called "The Digital Learning Transition in K-12 Schools" in spring and fall 2013. The courses were offered to educators from the USA…

This paper reports a 5-year design experiment on cumulative knowledge building as part of an international project. Through a longitudinal study and analysis of cumulative research data, we sought to answer the question, "what happened and why in knowledge building?" Research data constitute messages which participants have written into a shared…

In the last decade, we have seen the emergence of virtual learning environments. Initially, these environments were a little more than document repositories that tutor used unicast to the students. Informed in part by social constructivist theories of education, later environments included capabilities for tutor-student and student-student,…
