Only a few studies have dealt with the challenge of bridging the linguistic gap between the dialogic realm and the talk of disengaged students. Bridging this gap is particularly relevant to the CSCL community since one of its utmost aims is to promote the dialogic. This study aims to articulate how to harness the CSCL design and affordances to…

Changing practices in schools is a very complex endeavor. This paper is about new practices we prompted to foster collaboration and critical reasoning in science classrooms: the presentation of pictures representing different perspectives, small group synchronous argumentation, and moderation of synchronous argumentation. A CSCL tool helped in…

In this paper, we present findings on moderation of synchronous, small-group argumentation in blended, co-located learning environments. Drawing on findings from the literature on human facilitation of dialogue in face-to-face settings, we first elaborate on the potential promise of this new practice. However, little is known about what…

Argumentative activity has been found beneficial for construction of knowledge and evaluation of information in some conditions. Many theorists in CSCL and some empiricists have suggested that graphical representations may help in this endeavor. In the present study, we examine effects of type of ontology and of synchronicity in students that…

Critical reasoning has been recognized as a valuable educational goal since the end of the nineteenth century. However, the educational programs to reach this goal have changed dramatically during the twentieth century and moved to a dialogic approach. The shift to dialogism in programs to promote critical reasoning brings challenges concerning…
