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. To enhance communication and interaction between virtual characters and learners, we propose a three tier framework of fifteen research-based guidelines. This framework enables theorists, researchers, and designers to view virtual characters with a holistic lens, informing the analysis, design, development, implementation, and evaluation of virtual characters in electronic learning contexts.

The impact and implications of virtual character expressiveness on learning and agent-learner interactions Veletsianos, George (Journal of Computer Assisted Learning, 2009)The possible benefits of agent expressiveness have been highlighted in previous literature; yet, the issue of verbal expressiveness has been left unexplored. I hypothesize that agent verbal expressiveness may improve the ...
Contextually relevant pedagogical agents: Visual appearance, stereotypes, and first impressions and their impact on learning Veletsianos, George (Computers & Education, 2010)Humans draw on their stereotypic beliefs to make assumptions about others. Even though prior research has shown that individuals respond socially to media, there is little evidence with regards to learners stereotyping ...
