教师在备课时通常会对课堂教学过程做出各种预设。然而学生的灵活参与,以及一些偶发的课堂资源,会让课堂生成出乎意料。合理利用课堂资源能让知识的获取水到渠成,在学生学得轻松自然的同时让数学课堂充满活力。那么课堂中有哪些宝贵的资源呢?如何挖掘出“潜伏”的课堂资源?这就需要教师们有一双慧眼,善于观察发现课堂中存在的资源并加以利用。本文将从基础资源、对比资源、生成资源、 Teachers usually make various assumptions about classroom teaching process during lesson preparation. However, the flexible participation of students, as well as some occasional classroom resources, will make the classroom generated unexpectedly. Rational use of classroom resources can make knowledge acquisition easy and quick, make the mathematics classroom full of vitality while students learn easily and naturally. So what are the valuable resources in the classroom? How to dig out the “latent” classroom resources? This requires teachers have a pair of eyes, good at observing the resources found in the classroom and make use of it. This article will be from the basic resources, contrast resources, generate resources,
