问题意识是指学生在学习活动中,对教材中的一些理论知识或知识形成过程中发生的问题,因产生疑惑而形成的一种心理情绪。正因为有了这种心理情绪,才促使学生产生积极的思维,通过思考讨论和动手实践,找到解决问题的方法。正如爱因斯坦所说:“提出一个问题往往比解决一个问题更重要。”因此,课堂教学中教师要特别注重培养学生的问题意识。下面以高中化学教学为例,谈一下笔者在这方面的做法。 Problem awareness refers to students in learning activities, some of the theoretical knowledge in the textbook or knowledge of the formation of problems in the process of formation, because of doubt and the formation of a psychological emotion. Precisely because of this psychological mood, students are encouraged to produce positive thinking and to find solutions to problems by thinking and discussing and practicing. As Einstein put it: “It is often more important to ask one question than to solve one.” Therefore, teachers in classroom teaching should pay special attention to cultivating students’ problem awareness. The following high school chemistry teaching, for example, talk about the author’s practice in this regard.
