通过对概念的二次教学,深刻感受数学的思维方式,领悟概念中所蕴含的数学思想方法,并能够灵活运用这些思想方法解决与之相关的数学问题。这应该才是数学概念二次教学的根本目的所在。在整个高三数学复习的过程中,学生要经历很多次的模拟考试。在每次考试中,学生都会暴露出许多学习上的不足,经常在教师认为不该犯错误的地方出错。事实上,作业或者考试失误的主要原因是练得太少了,基本概念不清楚、不够熟练,答题准确率低。 Through the teaching of the second concept, I deeply feel the way of thinking in mathematics, comprehend the mathematical ideas and methods contained in the concept, and can flexibly use these ideas and methods to solve the related mathematical problems. This should be the fundamental purpose of the second teaching of mathematical concepts. Throughout the third year math review process, students go through many simulated exams. At each exam, students expose many learning deficiencies and often make mistakes where teachers think mistakes should not be made. In fact, the main reason for homework or test mistakes is too little exercise, the basic concepts are not clear, not proficient, the accuracy of the answer is low.
