衡量一名优秀的数学老师有两个重要的标准:课堂授课和解题能力,如何选题、怎样解题是每一位数学老师在教学过程中必须要认真解决的。著名美籍匈牙利数学家治·波利亚指出:“中学数学教学的首要任务就是加强解题的训练”、“解题是一种实践性技能,就像游泳、滑雪或者弹钢琴一样,只能通过模仿和实践来学到它”。我们在解题中一定要注重解题技巧的发现,培养发散的思维,用发现的眼光去看待问题,得到更多的化解问题的方法。一题多解体现 There are two important criteria for measuring an excellent math teacher: class teaching and problem solving skills, how to choose a topic, and how to solve each problem. Every math teacher must be conscientiously solved during the teaching process. The famous American Hungarian mathematician George Polia pointed out: “The primary task of mathematics teaching in secondary schools is to strengthen the training of problem solving.” “Problem solving is a practical skill, like swimming, skiing or playing the piano. It can only be learned by imitation and practice. ” We must pay attention to solve the problem-solving skills in the discovery, cultivating divergent thinking, with the vision to see the problem, get more ways to resolve the problem. More than a solution to the problem
