This paper presents a quantitative approach to multimodal discourse analysis for analyzing online collaborative learning. The coding framework draws together the fields of systemic functional linguistics and Activity Theory to analyze interactions between collaborative-, content- and technology-related discourse. The approach is used to examine…

In this article, we extend previous work with respect to interrater reliability measure of computer-mediated conferencing and suggest coding categories relevant to problem-based learning. Calculating interrater reliability agreement by using a Transcript Reliability Cleaning Percentage (TRCP) approach is simple for academics with limited…

Looks for appropriate interaction analysis/content analysis techniques that assist in examining the negotiation of meaning and coconstruction of knowledge in collaborative learning environments facilitated by computer conferencing. Reviews strengths and shortcomings of existing interaction analysis techniques and proposes a new model based on…

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…

The Virtual Classroom(TM) is a teaching and learning environment constructed in software, which supports collaborative learning among students who participate at times and places of their choosing. While students may access only the record of their activities, the instructor can review the activities status of any student, require that activities…

Discusses the effectiveness of computer mediated communication (CMC) in higher education. Highlights include a review of pertinent literature; factors associated with successful CMC resources; activity theory; helping users establish a shared purpose; methodological problems; evaluation methods; a conferencing system; and the patterns and content…

Educational researchers have employed various self-efficacy instruments in a wide spectrum of disciplines and academic settings. However, self-efficacy measures specific to the online environment have not been developed yet. This paper provides a brief history of the online environment and discusses the development and validation of an instrument…

Presents encouraging empirical findings related to an attempt to create an efficient and reliable instrument to assess the nature and quality of critical discourse and thinking in a text-based educational context. Suggests that cognitive presence (critical, practical inquiry) can be created and supported in a computer-conference environment with…

The web has the potential to offer an environment that can support standardized medical education to students dispersed in time or place and, in the process, respond to reduced availability of patients for practice. This exploratory article describes how we evaluated critical thinking in an online collaborative Problem-based Learning (PBL)…

Reports on a study of the characteristics of interactions in the computer conferences on "TeleNex", a computer network for the professional development of English as Second Language (ESL) teachers in Hong Kong. A framework of message analysis is described and results of a user questionnaire are discussed. (Author/LRW)

The use of activity theory is considered in the evaluation of a web based academic writing course in a New Zealand university. Activity theory is an aspect of sociocultural theory and provides a model for the understanding of goal directed social activity. Like other recent developments in applied linguistics, research and evaluation in second…
