大学英语四级阅读真题仔细阅读1
Questions 46 to 50 are based on the followingpassage.
For thousands of years, people have known that thebest way to understand a concept is to explain itto someone else. "While we teach, we learn," saidRoman philosopher Seneca. Now scientists arebringing this ancient wisdom up-to-date. They're documenting why teaching is such a fruitfulway to learn, and designing innovative ways for young people to engage in instruction.
Researchers have found that students who sign up to tutor others work harder to understandthe material, recall it more accurately and apply it more effectively. Student teachers scorehigher on tests than pupils who're learning only for their own sake. But how can children, stilllearning themselves, teach others? One answer: They can tutor younger kids. Some studieshave found that first-born children are more intelligent than their later-born siblings (兄弟姐妹). This suggests their higher IQs result from the time they spend teaching their siblings. Noweducators are experimenting with ways to apply this model to academic subjects. Theyengage college undergraduates to teach computer science to high school students, who in turninstruct middle school students on the topic.
But the most cutting-edge tool under development is the "teachable agent"—a computerizedcharacter who learns, tries, makes mistakes and asks questions just like a real-world pupil. Computer scientists have created an animated (动画的) figure called Betty's Brain, who hasbeen "taught" about environmental science by hundreds of middle school students. Studentteachers are motivated to help Betty master certain materials. While preparing to teach, theyorganize their knowledge and improve their own understanding. And as they explain theinformation to it, they identify problems in their own thinking.
Feedback from the teachable agents further enhances the tutors' learning. The agents'questions compel student tutors to think and explain the materials in different ways, andwatching the agent solve problems allows them to see their knowledge put into action.
Above all, it's the emotions one experiences in teaching that facilitate learning. Student tutorsfeel upset when their teachable agents fail, but happy when these virtual pupils succeed asthey derive pride and satisfaction from someone else's accomplishment.
