数学课上学生异口同声地回答问题的现象屡见不鲜,对此,教师要做到:在教学中倡导学生通过自主提问,真正成为学习的主体;立足知识点让学生自主建构;利用头脑中已有的模型建立新的模型;利用已悟的数学思想建立解题思路。课堂上要让学生在跌跌撞撞中根据自己的需要和认知结构、已有的经历去理解、感受、建构知识,从而生成自己对知识的独特感受、体悟和意义。 In the mathematics class, students unanimously answer the same questions frequently. In this regard, teachers should do the following: Advocate students through teaching in their own questions and truly become the main body of learning; based on knowledge points to enable students to construct their own; use existing models in the mind Establish a new model; use the comprehension of mathematical ideas to establish problem solving ideas. In the classroom, students should be allowed to stumble upon themselves according to their own needs and cognitive structures, and their experiences to understand, feel and construct knowledge so as to generate their own unique feelings, perceptions and meanings of knowledge.
