高中数学与初中数学相比,知识内容的整体数量剧增,逻辑性增强,思维方法向理性层次飞跃,因此,许多高中生感觉学习数学非常吃力,并且对数学学习的积极性不高,甚至许多高中数学教师在历年教学经验中发现许多学生在解题过程中都会对同一知识点出现类似错误。错题反映的是学生对某一知识点的掌握程度,奇怪的是,相对于较复杂的知识点而言,学生常常在比较简单的问题上出错,我们称这些知识点为易错点。易错点在高中数学中非常常见,在学生数学学习过程中起到了非常大的干扰作用,如何减少学生的易错点成为许多高中教师不断探索的问题。本文通过分析高中数学易错点的成因,提出提前干预的方法,巩固高中生基础知识,培养学生数学解题能力,提高学生学习兴趣。 Compared with junior middle school mathematics, the overall quantity of knowledge content increases sharply and logically, and the thinking method leaps toward the rational level. Therefore, many high school students feel that it is very difficult to learn mathematics and their enthusiasm for mathematics learning is not high. Even many high schools Mathematics teachers in the teaching experience over the years found that many students in the process of solving problems will have a similar error on the same knowledge point. The errors reflect students’ mastery of a particular point of knowledge. Curiously, students often make mistakes on simpler questions than more complex ones, which we call easy-to-miss points. Error-prone points are very common in high school mathematics and play a very big interference role in students ’mathematics learning. How to reduce students’ misjudgment has become a problem constantly explored by many high school teachers. Based on the analysis of the causes of mistakes in senior high school mathematics, this paper puts forward the method of early intervention, consolidating the basic knowledge of senior high school students, cultivating the students ability to solve problems in mathematics and improving students’ interest in learning.
