传统数学教学中,教师掌控着整个课堂教学,是课堂的主宰者,毫不在意学生的学习情况,也不会关注学生的学习情感,只是一味地讲课,将传递知识作为自己唯一的教学任务,更不会关注课堂预设与生成,即使遇到突发状况,教师也会选择直接跳过。这样使得学生对数学越来越迷惑,学生的学习效率也越来越低。因此,教师在教学中必须改变这一教学观念,要充分了解学生,从学生的角度来精心预设、调整预设、放弃预设,实现完美的生 In the traditional mathematics teaching, the teacher controls the whole classroom teaching, is the master of the classroom, does not care about the student’s learning situation, also does not pay attention to the student’s study emotion, only blindly lectures, will pass the knowledge as own only teaching task, Not to mention the default classroom and generate, even in unexpected situations, teachers will choose to skip directly. This makes students more and more puzzled in mathematics, students learn efficiency is getting lower and lower. Therefore, teachers in teaching must change this teaching concept, we must fully understand the students, from the perspective of the students to carefully preset, adjust the default, to give up the default, to achieve a perfect life
