Pedagogical Agents: Pedagogical Interventions via Integration of Task-Oriented and Socially-Oriented Conversation

  • a math game, focus on training basic concepts with spatial representation
  • student can play individually, learn how it works
  • train a teachable agent
    • job is to teach agent how to play game
    • learns by watching students
    • also poses questions (MC) - asks student to explain how the game works, rules etc
    • when agent has watched a few times, it can play autonomously
      • student is still helping agent (agree with choice or not)

System architecture

  • math game
    • teachable agent
    • on-task conversation
  • visual representation
  • social (off-task) conversations (chat with agent, abt music, family)
    • off-domain conversation
    • on-domain conversation

Possible reasons for adding socially oriented communication

  • increase overall engagement and receptivity
  • improve recall of learning material through emotional engagement
  • social experience helps cement newly learned associations
  • promote trust and rapport building
  • make students feel more at ease with learning task or topic

Research questions

  • can adding social conversation
    • enhance student's experience of game
    • influence students' self-efficacy and math attitudes
  • will social conversation module influence
    • game experience
    • learning outcomes

Some researchers would question adding off-task conversations - takes away focus from task

Result

  • high achievers have more positive experience and better learning outcomes
  • this did not apply to low achievers
  • low achievers chat more, but high achievers like it more
  • possible explanation
    • in situation of disengaged chat
      • low achievers keep chatting, high achievers do something about it
  • can engage learners in voluntary on-domain chat (1/3 initiated chat conversations about the math game)

Next step

  • Closer integration between task-oriented vs socially-oriented communications (related to the last result)
