弗赖登塔尔所说:“学习数学的唯一正确方法就是实行‘再创造’,也就是由学生本人把要学的东西自己去发现或创造出来。”学生只有真正经历数学知识的产生、发展和形成过程,其主动性、探索性才能得到真正的发挥,学生的观察、猜测、推理、概括、分析和解决问题的能力才能得到提高,对数学知识才会深刻的领悟,才会逐步形成数学化观念,同时,学生才会具有学习的后劲,得到全面可持续性的发展。让数学教学走向深刻,课堂教学中要注意哪些呢?下面就具体的案例来谈谈我的做法。 Freudenthal said: “The only correct way to learn mathematics is to practice ’reinventing’, which is to discover or create by the student himself what he or she wants to learn.” "Students only really experience mathematical knowledge , Development and formation process, its initiative and exploration can be truly played, students’ ability to observe, guess, reason, summarize, analyze and solve problems can be improved, the mathematical knowledge will be profound insight, will gradually The formation of mathematical concepts, at the same time, students will have the stamina of learning, be fully sustainable development. Let the mathematics teaching go deep, which should be noticed in the classroom teaching? Here’s a concrete case to talk about my practice.
