Description¶
Baylor and Kim (2005) designed three instructional agent roles grounded in social-cognitive perspectives of learning. The Expert provided accurate information with authoritative speech and deictic gestures; the Motivator modeled coping strategies as a peer with emotional expressions; the Mentor combined both functions. Table 1 operationalized each role by "Appearance (image), Animation, Voice, Affect and messaging (script)." The roles were instantiated through pre-scripted agents with controlled gender, lip synchronization, and script length.
Design Implications¶
Context¶
Requirements¶
- Learners must perceive the agent as intended; role instantiations require coordinated appearance, animation, voice, affect, and script
Constraints¶
- Agent-learner interactions were pre-scripted so each learner received all guidance, which limited the intelligence of the agents
Target Learners¶
- undergraduate students
Learning Goals¶
- computer literacy skills
- instructional design skills
Claims¶
- The Mentor agent had the overall best combined impact on learning and motivation [+M]
- Motivational agent roles (Motivator and Mentor) were perceived as more human-like and improved learner self-efficacy [+M]
- Agents with expertise (Expert and Mentor) improved learning outcomes and were perceived as more credible [+M]
- Split-persona effect: two distinct agent roles (Expert and Motivator) outperformed one combined Mentor agent [+M]
