Many studies have been conducted on the topics of tools, computers, and technology designed to promote student learning. However, researchers have rarely raised the critical issue of the lack of consensus on conceptualizing "cognitive tools" or the possible challenges associated with previous definitions. By examining the limitations on research…

"Second Life" is a popular example of an immersive, three-dimensional, virtual world. Inhabitants of "Second Life" often describe their experiences in-world as having great social presence. Certainly there is a good deal of potential for education and training to occur in multi-user virtual environments (MUVEs), if designed properly, especially…

The rapid growth of technology has made online tools available for education. The ability to discern the characteristics of these tools and to use them appropriately for educational purposes has become increasingly critical. Weblogs and discussion forums are among those up-and-coming tools that have great potential in supporting learning. They…

Examines the term interactivity as it is used in educational computing, and suggests that by applying deconstructive criticism new perspectives may be gained. Discusses learner control, non-linearity, and flexibility, and concludes that interactivity is not a conceptual unity. (LRW)

This article discusses the importance of private interactions, in which a student works alone with learning materials, and public interactions, in which a group of students engage in discourse around learning materials. While traditional technology requires that designers choose one type of interaction over another, the authors show how handheld…

Looks at some key elements of teachers' knowledge and skill bases and considers how these might be supported in Web-based instruction. Describes the "micro-genres" that constitute the instructional events of the online class. Introduces a software package to demonstrate how these interactions may be facilitated in practice.

Discusses engagement theory (students meaningfully engaged in learning activities through interaction with others and worthwhile tasks) and the three components, collaboration, project orientation, and authentic focus, and outlines research questions to establish its efficacy. (PEN)
