波利亚有句名言:“掌握数学就意味着善于解题。”培养小学生解决问题的能力,发展数学思维,是课程标准的重要目标。但是,“审题不仔细”“、分析不深入”“、策略不优化”等问题,在小学生中仍有一定的普遍性。如何转变这些不良倾向,提升小学生解题能力,笔者进行了初步的探索与尝试。一、直观表征,正确把握题意表征是影响问题解决的一个重要因素,正确表征往往有助于问题的解决;反之,问题表征不精确或不完全,就会造成问题解决的困难。1.画图明意,图表直观有些数学问题信息较多,数量关系比较复杂,给学生正确把握题意增添了困难。对于这类问题,教师可以引导
Polygam has a famous saying: “Mastering mathematics means being good at problem solving.” Developing pupils’ ability to solve problems and developing mathematical thinking are important goals of the curriculum standards. However, there are still some generalities among primary school students in such questions as “not carefully examining the subject”, not analyzing deeply “” and “not optimizing strategy”. How to change these undesirable tendencies and improve their ability to solve problems, the author conducted a preliminary exploration and attempt. First, the intuitive characterization, correctly grasp the problem representation is an important factor affecting the problem solving, correct characterization is often helpful to solve the problem; the other hand, the problem is not accurate or incomplete character, it will cause problems to solve the problem. 1. Drawings clear, visual chart Some math problems more information, the relationship between the number of more complex, to the students to grasp the meaning of the problem added to the difficulties. For such problems, teachers can guide
