著名数学教育家乔治·波利亚指出:“中学数学教学的首要任务就是加强解题训练,掌握数学意味着什么?这就是善于解题”.解题是数学的核心,解题能力是衡量一个人数学水平的重要标志,搞好解题教学则有利于提高学生的解题能力.而日常的解题教学活动往往没有能够取得预期的教学效果,师生一起陷在题海中,为解题而解题,学生的解题能力没有显著的提高,甚至还会出现遇到条件稍加改变,或者只是呈现形式有变化的题目,学生仍然不会做的现象,遇到新的问题更是无从下手,不会分析,没
The famous mathematics educator George Polya pointed out: “The primary task of middle school mathematics teaching is to strengthen problem-solving training. What does it mean to master mathematics? This is good at solving problems.” Solving problems is the core of mathematics, and the ability to solve problems is Measure an important symbol of a person’s mathematics level, do a good job solving the problem is conducive to improving students’ ability to solve problems. The daily problem-solving teaching activities are often not able to achieve the desired teaching effect, teachers and students are trapped in the sea, to solve Questions and problem solving, students’ problem-solving abilities have not been significantly improved, and even problems with slightly changed conditions, or only changes in the presentation of the topic, the students still do not do the phenomenon, encountered new problems is No way to start, no analysis, no
