We examine the effect of online Argumentation Vee Diagrams (AVDs) on the quality of students' argumentation during asynchronous, online discussions. With AVDs, students develop arguments on both sides of a controversial issue and then develop an integrated, overall final conclusion. In this study, students used AVDs individually before composing…

This article describes the impact of learning in asynchronous discussion groups on students' levels of knowledge construction. A design-based approach enabled the comparison of two successive cohorts of students (N = 223 and N = 286) participating in discussion groups for one semester. Multilevel analyses were applied to uncover the influence of…

Traditionally, universities focus primarily on instructionist teaching. Such an understanding has been criticized from theoretical and practical points of view. We believe that "socio-cultural theories of learning" and the concepts of "social capital" and "social creativity" hold considerable promise as a theoretical base for the repositioning of…

This qualitative case study illustrates barriers to informal argumentation and reasoned debate, i.e., "critical discourse," in online forums. The case is the computer conference of a 15-week, graduate-level humanities course offered entirely at a distance. Twelve students, all with families and careers, were enrolled in the course. We read all…

The focus of this study is to explore the advances that Social Network Analysis (SNA) can bring, in combination with other methods, when studying Networked Learning/Computer-Supported Collaborative Learning (NL/CSCL). We present a general overview of how SNA is applied in NL/CSCL research; we then go on to illustrate how this research method can…

The analysis of the process of collaboration is a central topic in current CSCL research. However, defining process characteristics relevant for collaboration quality and developing instruments capable of assessing these characteristics are no trivial tasks. In the assessment method presented in this paper, nine qualitatively defined dimensions of…

We describe the design of a knowledge-building environment and examine the role of knowledge-building portfolios in characterizing and scaffolding collaborative inquiry. Our goal is to examine collaborative knowledge building in the context of exploring the alignment of learning, collaboration, and assessment in computer forums. The key design…

Very often, when using a chat tool where more than one participant is talking simultaneously, it is difficult to follow the conversation, read all the different messages and work out who is talking to whom about what. This problem has been dubbed "Chat Confusion." This article investigates this problem in debate sessions in an online university…

This article presents findings from a comparative case study of the learning experiences of two graduate students in an online action research course. The key roles played by reflection and co-reflection, an emerging concept, are identified through the use of narrative analysis. Co-reflection is a collaborative critical thinking process mediated…

The purpose of this study is to refine Japanese elementary science activity structures by using a CSCL approach to transform the classroom into a knowledge-building community. We report design studies on two science lessons in two consecutive years and describe the progressive refinement of the activity structures. Through comparisons of student…

Since 1998, we have been developing and researching CoWeb, a version of Wiki designed to support collaborative learning. In this article, we summarize our results of situating CoWeb across the academic landscape of Georgia Tech. In architecture, CoWeb enabled faculty to serve more students in a design-based course. In English composition, a…

This paper describes the application of a mixed-evaluation method, published elsewhere, to three different learning scenarios. The method defines how to combine social network analysis with qualitative and quantitative analysis in order to study participatory aspects of learning in CSCL contexts. The three case studies include a course-long,…

A system for "anchored discussion" is compared with a system for traditional forum discussion (Blackboard), and their collaborative and communicative affordances for the collaborative processing of academic texts are investigated. Results show that discussion in the system for anchored discussion is more directed at processing the meaning of texts…

The authors work as online tutors for a BSc (Hons) physiotherapy programme at Coventry University in the United Kingdom. This paper represents a stage in our developing understanding, over a 3 year period, of the impact of group dynamics on online interaction among physiotherapy students engaged in sharing with their peers their first experiences…

Future CSCL technologies are described by the community as flexible, tailorable, negotiable, and appropriate for various collaborative settings, conditions and contexts. This paper describes the key design issues of a generic synchronous collaborative learning environment, called Omega+. In this approach, model-based genericity is applied to the…
