“问题—建模—应用”教学模式来源于美籍匈牙利数学家乔治·波利亚的“数学启发法”,它的指导思想是:一切从学生的学习、生活实际出发,问题让学生在教师指导下主动探求,建立数学模型,最后用所习得的知识技能、数学思想和方法去解释或解决实际问题。小学数学课堂教学如何实施这一模式呢? 一、问题 问题是需要探讨加以解决的疑难、矛盾,是一个人能做什么与 The “problem-modeling-application” teaching mode comes from the Mathematical Enlightenment Law of the Hungarian mathematician George Polia. Its guiding ideology is that everything starts from the students' study and life, Under the guidance of active exploration, the establishment of mathematical models, and finally use the acquired knowledge and skills, mathematical ideas and methods to explain or solve practical problems. How to implement this model in primary mathematics classroom? First, the problem is the need to explore the problems to be solved, the contradiction is that one can do with
