This paper introduces the pedagogical agents and describes its characteristics and roles in multimedia modules. It will also include examples of the use of pedagogical agents in previous studies and effective use of pedagogical agents on learning. Next, pedagogical agent variability in terms of physical (ethnicity, gender, image, voice) and internal features (roles, communication and competency) will be discussed in the context of its impact on learners' diversity. This is then followed by a discussion and suggestions for further research regarding the effective use of pedagogical agent in multimedia modules. ?? 2010 Published by Elsevier Ltd.
