But lectures, whether online or in the flesh, play onlya limited role in education. Research shows that thehuman brain accepts new concepts largely throughconstant recall while interacting socially. Thissuggests that good teaching must de-emphasiselecture and emphasise active problem-solving, saysCarl Wieman, a winner of the Nobel prize in physicsand an adviser to Barack Obama.
然而,无论是在网上还是在课堂中,这些课程都只能起到有限的教育效果。研究表明,人脑主要是通过在互动中不断回忆来接受新鲜概念。这也就是说高质量的教学必须像CarlWieman说的那样,要弱化老师授课,着重鼓励同学主动解决问题, Carl Wieman是物理学诺贝尔奖得主,也是奥巴马总统的顾问。
To KhanAcademys fans, the flip that Mr Khan advocates helps to do just that. As a tool,KhanAcademy individualises teaching and makes it interactive and fun. Maths is social now,says Kami Thordarson, as the 10-year-olds in the 5th-grade class she teaches at Santa RitaElementary School huddle round their laptops to solve arithmetic problems as though theywere trading baseball cards or marbles.
对于Khan学院的粉丝们来说,Khan先生所倡导的转变就是要增加互动。Khan学院将教学变得个性化、互动化和娱乐化。数学教学充满了合作与互动, Kami Thordarson说道,在她教授的Santa Rita小学五年级的课堂上,一群10岁的小学生挤在电脑旁,他们做数学题的方式就好像在交换宝石或是棒球卡。
