我国著名教育家陶行知有诗云:“发明千千万,起点是一问,禽兽不如人,过在不会问,智者问的巧,愚者问的笨,人力胜天工,只在每事问。”问题是引发思维,积累知识和创造发展的逻辑力量,是生长新思维,新方法,新知识的种子。教师把握好课堂设疑,对增强学生学习兴趣,发挥整体作用,发展思维能力,提高课堂教学的效率和教学质量都有十分重要的意义。 Tao Xingzhi, a well-known educator in our country, has a poem saying: “The invention of tens of millions of questions starts with a question that beasts are not as good as people. Without asking, the wise men ask Qiao, Everything is a question. ”The problem is the logical force that initiates thinking, accumulates knowledge, and creates development. It is the seed that grows new thinking, new methods, and new knowledge. Teachers have a good grasp of the classroom in doubt, to enhance students’ interest in learning, play an integral role, develop thinking ability, improve the efficiency of classroom teaching and teaching quality are of great significance.
