通过第一轮的复习,学生大都能掌握基本知识、基本技能、基本方法和基本思想,但这些方面的知识,总的感觉比较零散,同时,对于综合应用方面存在较大的问题.因此,在第二轮复习中,首要的任务就是能把整个高中的知识网络化、系统化,把所学的知识连成线,铺成面,织成网,梳理出知识结构,使之有机地结合在一起;其次,通过知识专题和方法专题的复习,应总结提炼并建构起数学思想方法系统,使解题策略与方法明确化、系统化.因此,第二轮复习承上启下,是强化主干内容,把握知识的内在联系,通过解题训练,提升实战能力的关键时期.但在教学过程中,正确的观念和教学行为之间往往存在一些偏差(笔者戏称之为“七宗罪”),这些偏差如得不到及时纠正,将会影响学生数学水平和能力的提高!“罪”之一.强调专题,淡化“双基”
Through the first round of review, most students can master the basic knowledge, basic skills, basic methods and basic ideas, but the knowledge in these areas is generally scattered. At the same time, there is a big problem for comprehensive applications. Therefore, In the second round of review, the first task is to be able to networkize and systematize the knowledge of the entire high school, connect the learned knowledge into a line, spread the surface, weave it into a network, comb out the knowledge structure, and organically combine it. Together, secondly, through the review of topics and methods of knowledge, we should summarize and construct a system of mathematical ideas and methods so that strategies and methods for problem solving can be clarified and systematized. Therefore, the second round of review is the strengthening of the content of the backbone. The intrinsic link of knowledge, through problem-solving training, enhances the critical period of actual combat ability. However, in the teaching process, there are often some deviations between the correct concepts and teaching behaviors (the writer jokingly refers to the “seven sins”). If it is not corrected in time, it will affect the improvement of students’ mathematics level and ability!“Sin ”. Emphasize the topic, dilute “double base”
