古人云:“疑是思之始,学之端。”学有所疑,才会学有所思、有所得,才会产生兴趣,形成动力。我们在教学中,要解放学生的大脑,让他们敢想,解放学生的嘴巴,让他们敢问。更重要的是要培养学生质疑的兴趣,质疑的习惯。这样才能唤起学生创新意识、创新欲望、创新思维,提高学生创新能力。 The ancients said: “Suspected is the beginning of thinking, the end of learning.” "Learning suspicious, will learn something, have income, will have an interest to form a driving force. In teaching, we should liberate the students ’brains, let them dare to think, liberate the students’ mouths and let them dare to ask. More importantly, students should be questioned by the interest to question the habit. Only in this way can arouse students ’sense of innovation, desire for innovation, innovative thinking, and enhance students’ ability to innovate.
