数学的教与学离不开解题。数学教育家波雷亚曾说:“掌握数学就是意味着解题,”教导学生解题的目的,不能是例题,习题的堆积,使头脑中题库无限增大,而是要使学生通过解题,自觉掌握数学这个工具和解答问题的策略、方法。培养分析问题、解决问题的能力。因此,研究解答数学问题的策略、方法,应成为数学教育工作者探索的重要课题。本文从中学数学教材与教学出发,谈谈一种常用
The teaching and learning of mathematics is inseparable from the problem solving. Mathematical educator Porrea once said: “Mastering mathematics means solving problems,” teaching students the purpose of problem solving. It cannot be an example. The accumulation of exercises makes the question bank in the brain infinitely large, but it is necessary for students to solve the problem. Consciously master the mathematics tool and answer questions. Cultivate the ability to analyze problems and solve problems. Therefore, the study of strategies and methods to solve mathematics problems should become an important topic for math educators. This article starts from the middle school mathematics teaching materials and teaching, talk about a common
