Task
If you were to design a pedagogical agent, what choices would you make, and what
would those choices depend on?
![Page 9: If you could design a teacher, what choices would you make? Answers … · 2011-04-07 · If you could design a teacher, what choices would you make? Answers from the Pedagogical](https://reader035.vdocuments.us/reader035/viewer/2022070900/5f365b9d832bea36585e24b4/html5/thumbnails/9.jpg)
3 scenarios
1. Whose goal is to motivate students to study history.
Design an agent:
2. Who teaches medical terminology.
3. Who scaffolds 14-year-olds in science inquiry.

The framework is at: http://www.veletsianos.com/2009/09/21/enali-pedagogical-agent-learner-interactions/
User Interaction example:
Pedagogical Agents should be attentive and sensitive to the learner’s needs and wants by:
• Maintaining an appropriate balance between on-and off-task communications.

The framework is at: http://www.veletsianos.com/2009/09/21/enali-pedagogical-agent-learner-interactions/
Message example:
Pedagogical Agents should consider intricacies of the message they send to learners by:
• Using congruent verbal and nonverbal messages.

Agent Characteristics example:
Pedagogical Agents should display socially appropriate demeanor, posture, and representation by:
• Being expressive (e.g. exhibiting verbal cues in speech).
• Using a visual representation appropriate to content.
