This qualitative case study sought to explore the social construction of knowledge in the Change My View (CMV) subreddit online community. Few of the prior studies of discussion in online courses found evidence of the higher Phases of knowledge construction (up to four and five of the IAM framework), and it was hoped that the CMV environment would…

Is it feasible to hold concurrent, small-group, peer-managed discussions in large elementary school classes? We sought an initial answer to this question in a fifth-grade class in Hefei, China. The 52 students in the class were divided into seven small groups. The seven groups held four simultaneous discussions without immediate supervision or…

In asynchronous threaded discussions, messages posted near the end of the week provide less time for students to critically examine and respond to ideas presented in the messages than messages posted early in the week. This study examined how the day in which messages are posted (early, midweek and weekend) in computer-supported collaborative…

This case study focused on whether women, enrolled in a graduate course, would engage in online debate, and if so, whether their postings would contain traditional elements of argumentation (i.e., argue, elaborate, critique). Content analyses for two debates were performed. For the most part, the overarching messages in both debates were…

This study examined how message-response exchanges produced in the interactions between active learners only, reflective learners only, active-reflective learners and reflective-active learners affected how often active versus reflective learners posted rebuttals to arguments and challenges across four types of exchanges that believed to promote…

Recent research indicated that students' ability to construct evidence-based explanations in classrooms through scientific inquiry is critical to successful science education. Structured argumentation support environments have been built and used in scientific discourse in the literature. To the best of our knowledge, no research work in the…

Numerous studies have affirmed the value of asynchronous online communication as a learning resource. Several investigations, however, have indicated that discussions in asynchronous environments are often neither interactive nor coherent. The research reported sought to develop an enhanced understanding of interactional coherence, argumentation,…

Newspapers and other media are often used as a source of information on science issues, both by the public and teachers in classrooms. Over six months, we collected discussions of global warming issues from the online forums of a national newspaper. Our analysis of these contributions suggests there is a considerable effort in these forums,…

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…

Many consider rich argumentation to be the core of quality discussions and view it as a vehicle to solving problems and clarifying content. This study examined the influence of a discussion leader intervention on the quality of online argumentation and interactivity. Subjects were 44 undergraduate students who participated in online discussions on…

In support of research examining relationships between learner characteristics and the quality of online discussions, this paper surveys different methods for evaluating discussions. The paper will present coding methods used in our own research as well as methods used by others interested in quality online discussions. Key topics include what…

This study tested the effects of linguistic qualifiers and intensifiers on the number and types of replies elicited per argument and per challenge posted in online debates. To facilitate collaborative argumentation, thirty-two students (22 females, 10 males) enrolled in a graduate-level online course classified and labeled their messages as…

Observation of 16 university students of writing in English as a Second Language in Taiwan focused on the nature of interactions during three peer response sessions and one consensus exercise. It examined the kinds of comments made by a writing group in responding to peer writing and the characteristics of the verbal interaction in a consensus…
