Designing collaborative three-dimensional learning games for vocational learning may be one way to respond to the needs of working life. The theoretical vantage points of collaborative learning for game development and the "design-based research" methodology are described; these have been used to support collaborative learning in the…

Pedagogic Conversational Agents are computer applications that can interact with students in natural language. They have been used with satisfactory results on the instruction of several domains. The authors believe that they could also be useful for the instruction of Secondary Physics and Chemistry Education. Therefore, in this paper, the…

In an earlier study, we had tested if observing a collaboration model, or alternatively, following a collaboration script could improve students' subsequent collaboration in a computer-mediated setting and promote their knowledge of good collaboration. Both model and script showed positive effects. The current study was designed to further probe…

This article describes an exploratory study of two Web-based learning environments designed to teach helping skills to human service students. Participants used either an interactive pedagogical agent environment or read a helper-client script. Environments were compared and learning gains were assessed in each of the environments, along with user…
