毕业生在高考前复习立体几何时,不少同学提出:“老师,重讲一遍吧,全忘了!”印象不深”!“空间想象力不强!”……。听到了同学们的反映,我感到了一个教师的责任。结果用了六周的时间,花了30多个课时才把立体几何复习了一遍。这一事实对我教育很大。学生的反映象一面镜子照出了我教学中的问题。的确,教学工作既是一门科学,又是一门艺术。如何使同学们学得会、学得好和记得牢、能应用是我们的教学目的。 When graduates reviewed the three-dimensional geometry before the college entrance examination, many students proposed: “Teacher, repeat it, forget everything!” Impression is not deep!” “Space imagination is not strong!” ..... Heard the reflection of the students. I felt a teacher’s responsibility, and it took six weeks and it took more than 30 hours to review the three-dimensional geometry. This fact taught me a lot. The student’s reflection mirrored me like a mirror. Problems in teaching. Indeed, teaching is both a science and an art. How to make students learn, learn, remember, and apply is our teaching purpose.
