亚里士多德曾说过:“思维是从疑问和惊奇开始的。”疑问能使学生心理上感到茫然,产生认知冲突,促使学生积极思考,主动参与到课堂教学中去,从而使学生的学习不仅是一个接受知识的过程,更是一个自主探究、合作互动、人人参与的过程。什么是问题?其实简单地说,就是你想做什么事,但你不知道如何做,那么你就遇到了一个问题。如果一个学生长期处于无“问题”状态,说明他思考不够,学习水平也提不高。因此,“问题”是学生提高学习能力的基础。 Aristotle once said: “Thinking begins with doubts and surprises.” “Questions can make students feel confused psychologically, resulting in cognitive conflicts, prompting students to think actively, take the initiative to participate in classroom teaching, and thus Making students learn is not only a process of accepting knowledge, but also a process of self-exploration, cooperation and interaction and participation of all. What is the problem? In fact, simply put, is what you want to do, but you do not know how to do, then you have encountered a problem. If a student is long without ”problem “ state, that he did not think enough, the level of learning is also not high. Therefore, ”problem " is the basis for students to improve their learning ability.
