Abstract
The broad use of computer-supported collaborative-
learning (CSCL) environments (e.g., instant messenger–
chats, forums, blogs in online communities, and massive open
online courses) calls for automated tools to support tutors in
the time-consuming process of analyzing collaborative conversations.
In this article, the authors propose and validate the
cohesion network analysis (CNA) model, housed within the
ReaderBench platform. CNA, grounded in theories of cohesion,
dialogism, and polyphony, is similar to social network
analysis (SNA), but it also considers text content and discourse
structure and, uniquely, uses automated cohesion indices
to generate the underlying discourse representation. Thus,
CNA enhances the power of SNA by explicitly considering
semantic cohesion while modeling interactions between participants.
The primary purpose of this article is to describe
CNA analysis and to provide a proof of concept, by using
ten chat conversations in which multiple participants debated
the advantages of CSCL technologies. Each participant’s contributions
were human-scored on the basis of their relevance
in terms of covering the central concepts of the conversation.
SNA metrics, applied to the CNA sociogram, were then used
to assess the quality of each member’s degree of participation.
The results revealed that the CNA indices were strongly correlated
to the human evaluations of the conversations.
Furthermore, a stepwise regression analysis indicated that
the CNA indices collectively predicted 54% of the variance
in the human ratings of participation. The results provide
promising support for the use of automated computational
assessments of collaborative participation and of individuals’
degrees of active involvement in CSCL environments.
