Computer Conferencing: An Environment for Collaborative Project-Based Learning in Distance Education

It is difficult to suggest a totally unambiguous strategy for formulating and managing online collaborative project work, however, some tentative suggestions are advanced.

Abstract

In this experimental study two independent variables were manipulated. Each was associated with online collaborative learning in a distance education context. One of these (group formation strategy) addresses one of the early decisions that must be made in forming groups for collaborative project work. The second (levels of tutor intervention) relates to the on-going process of group management in a computer-mediated environment. An additional independent variable (type of collaborative project) served as a within-group factor in the design. Two measures of individual achievement (final exam scores and idea units) and a measure of group dynamics served as dependent variables. Prior academic achievement (current grade point average) served as a covariate in the analysis of the achievement data. There were no differences across the two types of projects, but two slightly different interaction patterns emerged from the analysis of the achievement data. In general, however, these results favored the random assignment of students to collaborative groups (as contrasted with allowing students to pick their own partners) and the introduction of low tutor intervention during the course of project work. Two main effects emerged from an analysis of the group dynamics data, one of which supports the random assignment strategy. Because of these findings, it is difficult to suggest a totally unambiguous strategy for formulating and managing online collaborative project work. However, some tentative suggestions are advanced. Some guidelines for online collaborative learning are provided.
