We examined how social antecedents impact students' use of explanations versus evidence to justify arguments using "statistical discourse analysis" on 2028 postings from 87 graduate students in five courses, each participating in four online debates. The results show that students overall were much more likely to justify arguments with…

Online group debates hosted in asynchronous threaded discussions can facilitate critical thinking between discussants (and increase deeper understanding of complex problems) by eliminating the need for turn-taking while formulating and presenting premises to support and challenge claims. Yet to be determined is to what extent does the current…

Asynchronous discussions have been widely used in education to support learning. Exploring the reasons why threads in asynchronous discussion forums die may help us improve our understanding of asynchronous discussions and lead to a more effective learning process. This study explored why threads in asynchronous discussion forums shut down. Two…

At present, with the rapid development of the internet and the gradual promotion of online collaborative learning, the social regulation of learning is receiving increasing attention, which involves socially shared metacognition, one facet of social metacognition. To date, social regulation of learning or socially shared metacognition have been…

Given that grammatical and spelling errors have been found to influence perceived competence and credibility in written communication, this study examined how a student's grammar and spelling errors affect how other students respond to the student's postings in four online debates hosted in asynchronous threaded discussions. Message-response…

Meaningful learning requires deep engagement with ideas. Deep engagement is supported by the critical thinking skill of argumentation. Learning to argue represents an important way of thinking that facilitates conceptual change and is essential for problem solving. In order to appropriately apply argumentation practices to learning, we first…
