Some studies have found that first-born children are more __than their later-born siblings (兄弟姐妹)This__their higher IQs result from the time they spend teaching their siblings.

Now educators are experimenting with ways to__ this model to schoolwork. They engage college undergraduates to teach computer science to high school students, who then __ instruct middle school students on the __. But the most cutting-edge tool is the “teachable agent”-a computerized character who learns, tries, makes mistakes and asks questions just like a real-world__. Computer scientists have __ an animated(动画的)figure called Betty's Brain, who has beentaught about science by middle school stints. Student teachers are motivated to help Betty __ certain materials. While preparing to teach, they organize their knowledge and__ their understanding. And as they explain the information to it, they identify problems in their own__.

Feedback from the teachable agent __improves the teachers' learning. The agents' questions drive student teachers to think and explain the materials in different __,and watching the agent solve problems allows them emotions one experiences into action.__,it’s the emotions one experiences in teaching that help learning. Student teachers feel __ when their teachable agents fail, but happy when these pupils succeed as they gain pride and satisfaction from someone else’s achievement.
