问题的产生:“这道题讲了N遍还是错?简直服了他们了!”;“这道题就改了几个数据怎么就不会做了呢?真不知道现在的学生怎么了!”……办公室里经常能听到老师们这样抱怨。和大家一样,在小学数学教学中我也遇到了同样的困惑,我想:有效的数学教学离不开有效的作业订正,作业的订正情况直接反映了孩子们对知识的掌握程度,同时也是教师改进教学方法的重要依据。我不禁反思:学生的数学作业到底该如何订正才能真正有效? Problem: “This question told N times or wrong? Just served them!” “This question on how to change a few data will not do? I really do not know the students What's going on? ”" Often, teachers can complain in the office. Like everyone, I also encountered the same puzzles in elementary mathematics teaching. I think that effective mathematics teaching can not be separated from effective homework revision. The correction of homework directly reflects children's mastery of knowledge and is also a teacher An important basis for improving teaching methods. I can not help but reflect on how to correct a student's math homework effectively?
