课堂教学的效益来自于学生的思维活动,复习课要充分体现“以学生发展为本”的教学理念,教师通过对所学知识的再整合,形成系统的知识结构,提炼数学方法,感悟数学思想,培养学生良好的思维品质。不久前,在我校开展的一次合肥市初中数学教学学术研讨活动中,笔者听取了谢卫松老师的沪科版七年级上学期期末一节复习课《数轴再认识》,通过观摩研讨,深有体会。一、注重内在联系,构建知识体系【教学片断1】师:请画出一条数轴,并在数轴上用点A表
The effectiveness of classroom teaching comes from the thinking activities of students. The reviewing class should fully reflect the teaching concept of “developing students with the foundation”. Teachers re-integrate the knowledge they have learned, form a systematic knowledge structure, refine mathematical methods, Mathematical thinking, foster students’ good thinking quality. Not long ago, at a Hefei junior high school mathematics teaching academic seminar held in our school, the author listened to Xie Weisong’s Shanghai Chapter seventh grade last semester last year review section “re-understanding of the number of axes”, by observing and discussing, deeply understand . First, pay attention to the internal relations, the construction of a knowledge system [teaching piece 1] Division: Please draw a number of axes, and the number of points on the axis A table
