问题    For thousands of years, people have known that the best way to understand a concept is to explain it to someone else. "While we teach, we learn," said Roman philosopher Seneca. Now scientists are bringing this ancient wisdom up-to-date. They’ re documenting why teaching is such a fruitful way 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 understand the material, recall it more accurately and apply it more effectively. Student teachers score higher on tests than pupils who’ re learning only for their own sake. But how can children, still learning themselves, teach others? One answer; They can tutor younger kids. Some studies have 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. Now educators are experimenting with ways to apply this model to academic subjects. They engage college undergraduates to teach computer science to high school students, who in turn instruct middle school students on the topic.
   But the most cutting-edge tool under development is the " teachable agent" —a computerized character 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 has been "taught" about environmental science by hundreds of middle school students. Student teachers are motivated to help Betty master certain materials. While preparing to teach, they organize their knowledge and improve their own understanding. And as they explain the information 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, and watching 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 tutors feel upset when their teachable agents fail, but happy when these virtual pupils succeed as they derive pride and satisfaction from someone else’ s accomplishment.
What are researchers rediscovering through their studies?
选项 A、Seneca’s thinking is still applicable today.
B、Better learners will become better teachers.
C、Human intelligence tends to grow with age.
D、Philosophical thinking improves instruction.
答案A
解析 细节题。原文第一段第二、三句话指出，罗马哲学家塞内卡说：“我们教别人的同时，我们也在学习”。现在，科学家们正在把这一古老的智慧引人到当今世界中来。接着第二段指出，研究人员发现参与辅导他人的学生会得到更高的分数。由此可知，塞内卡这一思想在现代仍旧适用，故答案为A。B项将二者的关系颠倒了，原文强调的不是更好的学习者会成为更好的老师，而是教会别人的同时自己可以学习得更好，故排除。C、D两项原文均未提及，故排除。
