The current experimental study examined the effects of graphic organizers in a collaborative learning context where students constructed knowledge during online discussions. As the results could vary depending on how students interacted with the graphic organizers, this study compared two different approaches: instructor-provided versus…

Online discussions offer exciting potential for educational dialogue, but too often result in disjointed conversations with low levels of interactivity. One contributing cause is the traditional text-based interface, which presents posts in a long list, leaving students overwhelmed and without useful navigational cues. To address this problem, we…

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…

This study used a sequential set-up to investigate the consecutive effects of timing of supportive information presentation (information before vs. information during the learning task clusters) in interactive digital learning materials (IDLMs) and type of collaboration (personal discussion vs. online discussion) in computer-supported…

Betty's Brain is an open-ended learning environment in which students learn about science topics by teaching a virtual agent named Betty through the construction of a visual causal map that represents the relevant science phenomena. The task is complex, and success requires the use of metacognitive strategies that support knowledge acquisition,…

In this paper we report the results of a study which investigated the affordances of multi-user virtual environments (MUVEs) for collaborative learning from a design perspective. Utilizing a mixed methods approach, we conducted a comparative study of the effect of varying representational and interactional design features on a collaborative design…

The discussion forum is a significant component of online courses. Instructors and students rely on these asynchronous forums to engage one another in ways that potentially promote critical thinking, meaningful problem solving, and knowledge construction. In spite of the importance of these forums, predominantly used methods for assessing the…

Discussion of computer-mediated group problem solving focuses on a study of undergraduates that compared the perceptions of participants, the nature of the comments made, and the patterns of communication in face-to-face and computer conferencing groups in terms of problem-solving activities while solving well-structured and ill-structured…
