The purpose of this study is to provide conceptual order and a tool for the use of CMC and computer conferencing in supporting an educational experience. Central to the study introduced here is a model of community inquiry that constitutes three elements essential to an educational transaction -cognitive presence, social presence, and teaching presence. Indicators (key words/phrases) for each of the three elements emerged from the analysis of computer conferencing transcripts. The indicators described represent a template or tool for researchers to analyze written transcripts as well as a guide to educators for the optimal use of computer conferencing as a medium to facilitate an educational transaction. This research would suggest that computer conferencing has considerable potential to create a community of inquiry for educational purposes.The use of computer-mediated communication (CMC) is becoming increasingly common in higher education. Many higher education institutions are looking to CMC, particularly computer conferencing, as a versatile medium for the delivery of educational programs "anytime, anywhere."While those leading the development of this new medium are convinced of its potential, its effects on the quality of the learning process and its outcomes have not been well studied. The authors are engaged in a multi-faceted study that will help to remedy this gap in our knowledge base. The present paper is the keystone of a series of publications reporting the results of this ongoing research project.

This article describes a practical approach to judging the nature and quality of critical discourse in a computer conference. A model of a critical community of inquiry frames the research. A core concept in defining a community of inquiry is cognitive presence. In turn, the practical inquiry model operationalizes cognitive presence for the purpose of developing a tool to assess critical discourse and reflection. 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 textbased educational context are presented. Finally, it is suggested that cognitive presence (i.e., critical, practical inquiry) can be created and supported in a computer conference environment with appropriate teaching and social presence.

This paper presents a tool developed for the purpose of assessing teaching presence in online courses that make use of computer conferencing, and preliminary results from the use of this tool. The method of analysis is based on Garrison, Anderson, and Archer’s model of critical thinking and practical inquiry in a computer conferencing context. The concept of teaching presence is constitutively defined as having three categories – design and organization, facilitating discourse, and direct instruction. Indicators that we search for in the computer conference transcripts identify each category. Pilot testing of the instrument reveals interesting differences in the extent and type of teaching presence found in different graduate level online courses.

A recent book by Clayton M. Christensen, Associate Professor of Business at Harvard University, discusses the sometimes devastating impact in the corporate environment of what he refers to as "disruptive technologies." Successful, well-managed firms that dominate their markets have sometimes gone into a sharp decline or even collapsed when a new technology disrupts the pattern of their market segment. Other firms, however, have handled such transitions smoothly, maintaining their position of dominance in the market by employing specific techniques to integrate the new and disruptive technology into their operations.Traditional research universities enjoy a dominant position in the higher education "market," but they are beginning to feel the impact of disruptive technologies such as distance education. They may benefit not only from an examination of the insights that Christensen has derived from his study of the impact of disruptive technologies in the corporate environment but also from a selective application of the techniques for coping with disruptive technologies that Christensen has found to be effective in the business world. Some of these techniques imply an important role for continuing education units as semi-autonomous incubators of disruptive innovation.
