数学学习是从学生已有的生活经验出发,让学生自主地将实际问题抽象成数学模型并进行解释和应用的过程。这一理念注定数学学习是一个需要亲自经历、动手实践、主动探究的过程。教学是预设与生成、封闭与开放的矛盾统一体。在课堂上,老师需要留下适当的时间给学生,让学生有自由的空间和展现自我的机会,自觉地进行知识构造。这样才能使数学课堂更加充满活力。
Mathematical learning is based on the students’ existing life experience, allowing students to autonomously abstract practical problems into mathematical models and explain and apply them. This concept is doomed to mathematics learning is a need to experience in person, hands-on practice, take the initiative to explore the process. Teaching is the unity of contradiction between presupposition and formation, closure and opening. In class, the teacher needs to leave the right time for the students, giving the students the freedom to show themselves and the opportunities to self-consciously construct the knowledge. This will make mathematics classroom more dynamic.
