Does what happens in VR stay in VR? Daniel L. Schwartz Stanford University
Pat Kuhl U. Washington
Natural Question • Is it the social aspect of the interaction? • Or, is it the contingent aspect of the interaction? • Conducted a more controlled study with adults in immersive virtual reality (VR). • A “mere belief” manipulation. • Kept all interactions identical.

Agent condition – told the character is the computer.
Procedures. • College students. • Read a brief passage on the causes of fever. • Played “Operation” with confederate. • Into VR - told confederate (avatar) or computer (agent) • Read aloud questions relevant to fever passage. • Questions shown on a screen in VR. • “Why do your hands and feet get cold during a fever?” • Character answered after each question. • Answers were neither right nor wrong • Left VR and took a posttest.
Posttest Score Score if only repeated character’s answers
Arousal in VR on questions people did well or poorly on posttest.

Summary • Began with wrong question: Social OR Interaction. • Correct answer was: Social AND Interaction. • Social + Interaction increased arousal and learning. • Arousal correlated with learning. • LIFE checking arousal story. • Internal reward centers “turned up” in social exchange.
How do we bring this to classroom technology? • Bad approaches: • We lie and tell the kids the computer is a person. • We avoid all non-social uses of computers. • A better approach: • Social is a frame of mind. • After all in the VR study, it was always a computer. • Have students adopt a social frame of mind.
Teachable Agents (TA) Students learn by adopting and teaching a computer agent. GautamBiswas (Vanderbilt)

Does it work? Cathy Chase Stanford • Teach agent v. self. • 50 8th-graders. • “Mere belief” manipulation. • Identical software. • Teach condition learns better. • Low achiever boost. • Students work harder to learn for their agent than self. • Double reading time! Teach Self
Now what? • Do we leave kids in technology environment all the time? • Byron Reeves said life will be in technology, so why not? • Not quire ready to accept this argument. • Do students become too dependent on the technology? • Calculators and math, word processors and spelling. • Does technology displace the value of original curriculum? • One way to answer these later two questions: • Show that students learn better from their lessons after using the technology.
Does technology help or hurt learning in the long run? Cohort 1 Cohort 2 With TA No TA Doris Chin Stanford ~150 Children and 6 Teachers 6th-grade science All teachers used the same science kits. (FOSS). Half of teachers also used TA’s as they wished. Same total time overall.
Kit + TA Kit Only Average FOSS Item Score (0-1) Data What Why How Question Type Performance on FOSS kit’s own tests.(Is there added value without detracting from FOSS?)

Conclusion • Does what happen in VR stay in VR? • (Jeremy Bailenson wants all kids to wear VR in class.) • No: Results reaching out to learning theory and school applications. • Ditto for learning technology. • Agents prepared students to learn better without technology. • Thank you! • For more details, go to <AAALab.Stanford.Edu> to download: • Teachable Agents and the protégé effect. • Preparation for future learning with Teachable Agents. • The mere belief of social interaction improves learning.
