著名物理学家李政道教授曾说:“考试考得再好,也只是在回答别人提出的问题,一定要培养学生的好奇心,要敢于提出问题。”这里说的“提出问题”就是指让学生在学习过程中提出疑问。明代教育家陈白沙说:“学贵有疑,小疑则小进,大肆则大进。疑者觉悟之机也,一番觉悟,一番长进,更无别法也。”这些精当的论述,揭示了“疑问”在人们学习、掌握知识过程中的重要性。人的思维活动往往因一定的疑问而诱发。正象炸药的爆炸需要导火线一样,“疑问”是思维活动的导火线之一。“疑问”不但能引发思维,同时也能确定思维的方向,因为思维往往是围绕着一定的“疑问”进行的。 Professor Li Zhengdao, a famous physicist, once said: “The test is no better, just answering questions raised by others, we must cultivate the curiosity of students and have the courage to ask questions.” The question of “asking questions” refers to Students question the learning process. Chen Baisha, an educator in the Ming Dynasty, said: “There is doubt in your classics, small admissions, and large incursions. The chances for the suspect are also enlightenment, some progress, and no other reason.” These elaborate treatises , Reveals the importance of “doubt” in people's learning and mastery of knowledge. People's thinking activities are often induced by certain questions. Just as the explosives of dynamite need fuse, “doubt” is one of the fuse of thinking activity. “Doubt” can not only lead to thinking, but also determine the direction of thinking, because thinking is often around a certain “doubt” carried out.
