在高三化学总复习阶段,练习与测试占了较大的比例.因为测试可以巩固所复习的知识,检查学生的知识和能力的发展水平,诊断出存在的问题,给教师后面的教学提供了方向.而讲评课的教学重点与教学方式也需要教师再三斟酌,因为它是知识复习的补充.高效的讲评课应当让学生认识错误,重视知识与思维上的漏洞,规范解题习惯,提升解题的能力.为高三化学讲评课的有效性,笔者尝试了以下教学流程.
In the senior high school chemistry general review stage, practice and test account for a large proportion.As the test can consolidate the knowledge reviewed, check the students’ knowledge and ability of the level of development, diagnosis of the existing problems, to the teaching of teachers to provide the direction However, the emphasis and teaching methods of teaching comment class also require teachers to consider it again and again, because it is a supplement to knowledge review.Efficient comment class should allow students to recognize mistakes, attach importance to loopholes in knowledge and thinking, standardize the problem solving habits, enhance the problem solving Of the ability to comment on the effectiveness of the senior high school chemistry, the author tried the following teaching process.
