习题在《数学》教材中占有很大的比重,它也是数学课堂教学不可或缺的内容之一。学生通过解答《数学》教材上的习题,不仅可以巩固学生的数学知识,提升学生解决数学问题的技能,还可以在无形中向学生渗透数学思想。但是许多教师在审读教学教材上的题目时,总感觉不太切合本班学生的实际,所以经常会改动习题的内容与形式,想让练习题可以更好地促进学生数学素养的提升。但是由于改编时没有研读教材题目的内涵,造成改过的练习题更加不适合学生,甚至 Exercise in the “mathematics” textbook occupies a large proportion, it is also an integral part of mathematics classroom teaching. By answering questions on “math” textbooks, students can not only consolidate students ’mathematical knowledge, enhance students’ ability to solve math problems, but also immerse students in mathematics ideally. However, many teachers are not always satisfied with the actual situation of their students when they are reviewing the teaching materials. Therefore, they often change the content and form of the exercises so that the exercises can better promote the students’ mathematical accomplishments. However, due to the adaptation did not study the content of the textbook topics, resulting in modified exercises more inappropriate for students, or even
