一、背景阐述讲评课是中学教学过程中的一种常见课型,高质量的讲评课可以纠正学生在答题过程中暴露的问题,深化对知识的理解,弥补不足,提升以思维品质为核心的各种能力和素质.试卷的评讲成功与否,要看是否查明典型错误的存在,是否提出进一步克服困难的方法,是否保证学生对所做练习质量作自我检查,是否提升学生的逻辑思维能力.高三数学课的实际状况是时间紧任务重,讲评时匆匆忙忙,许多问题一带而过,不经意间就会错过很多经典例题,有时 First, the background description Commentary class is a common class in the teaching process of high school, high-quality comment class can correct the students exposed in the process of answering questions, deepen the understanding of knowledge, make up for lack of improvement of thinking quality as the core Whether it is to identify the existence of typical mistakes, whether to propose further ways to overcome difficulties, whether to ensure that students self-examination of the quality of the exercises, whether to enhance students’ logical thinking Ability. The actual situation of high school mathematics lesson is the task of time is tight, when commenting on the rush, many problems along, inadvertently will miss a lot of classic examples, and sometimes
