Knowledge elaboration plays a critical role in promoting knowledge acquisition and facilitating the retention of target knowledge in online collaborative discussions. Adopting a key-term-based automated analysis approach, we proposed an indicator framework to measure the level of knowledge elaboration in terms of coverage, activation, and…

In an online context, without facial, verbal or gestural cues, establishing identities through naming social positions appeared essential to effective written communication for graduate pre-service teacher candidates enrolled in a course on literacy education for elementary students. As they engaged in small group asynchronous discussions about…

This paper studies the social talk of high school students in online discussion forums. On-task talk has generally been assessed as valuable discussion because it contributes directly to productive learning. Off-task conversation, on the other hand, is often regarded as useless and a waste of time. Should this social talk indeed be regarded as an…

Using a discourse analytic qualitative approach, we investigated the naturally-occurring discourse that arose as part of two kinds of regular course activities, synchronous and asynchronous computer-mediated discussions. The messages contributed by members of a graduate course were analyzed for the kind of discourse functions and the kind of…

Pre-service teachers' perceptions of their own learning are important to the ways they integrate technology into their practices. Therefore, the purpose of this study was to examine the pre-service teachers' perspectives of asynchronous discussion board (ADB) as a tool of learning to teach. ADB was integrated into two literacy courses for 33…

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,…

This paper investigates the complex interactions that occur as teachers meet online to justify and negotiate their assessment judgements of student work across relatively large and geographically dispersed populations. Drawing from sociocultural theories of learning and technology, the technology is positioned as playing a role in either…

The study reported here sought to obtain the clear articulation of asynchronous computer-mediated discourse needed for Carl Bereiter and Marlene Scardamalia's knowledge-creation model. Distinctions were set up between three modes of discourse: knowledge sharing, knowledge construction, and knowledge creation. These were applied to the asynchronous…

This paper uses Conversation Analysis to investigate the ways in which participants in an online asynchronous postgraduate reading group managed and negotiated their contributions within the discussion. Using the conversation analytic concerns with sequential organisation, adjacency pairs and topicality, this article shows the analytic insights…

This study examines online messages in a discussion forum that a group of K-12 history teachers used to discuss curriculum implementations as part of their professional development. It has 3 main research foci. First, it focuses on identifying the types of assistances provided to the teachers in an online forum. Second, it examines teachers'…

Although protocol analysis can be an important tool for researchers to investigate the process of collaboration and communication, the use of this method of analysis can be time consuming. Hence, an automatic coding procedure for coding dialogue acts was developed. This procedure helps to determine the communicative function of messages in online…

Teacher education students have a significant role to play in the sustained application of ICT in schools. It is imperative therefore, that they are exposed to effective use of ICT in their training. However, "effective use" is subjective and existing characterisations of this construct appear to drive different ICT implementation plans…

A study compared the discourse within a knowledge-building community in dual mediums: face-to-face meetings and electronic mail postings to a discussion list. Participants were faculty members and graduate students at a major university. The study focused on patterns of participation in both mediums, changes in these patterns, and possible effects…
