Conflicts occur when learners interact with pedagogical agents and virtual characters. Such conflicts--arising from technological limitations, psychosocial perceptions, and pedagogical inadequacies--hinder communication and interaction between virtual characters and learners, and impede successful engagement with learning tasks and experiences.

Investigates the effect of activity content, its presentation, and the interactions between the two on flow experience (intrinsic motivation) in instructional activity. Results suggest that activity content has major influences on motivation; hypermedia presentations can add to motivation if used appropriately, or they can be distracting if too…

Describes how the structure of hypermedia systems can be represented by a simple matrix which is the basis for applying standard techniques of network analysis, and demonstrates the potential influence of these techniques on learning processes or outcomes. Also discusses theoretical and practical implications for future hypermedia research. (AEF)

Describes the design, implementation, and preliminary evaluation of three synchronous distributed learning prototype systems: Co-Working System, Working Along System, and Hybrid System. Each supports a particular style of interaction, referred to a socio-activity learning model, between members of student dyads (pairs). All systems were…
