长期以来,很多数学教师发现,在小学数学练习与测试中,学生普遍存在着做错的题有时一错再错的现象。面对学生的错误,教师一般是再讲解,学生再订正。教师不禁感叹:做过这么多遍,怎么还错?究其原因,其实是在教师讲解以及学生订正的过程中,学生是被动地接受知识,没有经历反思的过程,因而并没有真正理解错误的原因所在,正确的认识也没有真正建立起来。教师太过“操心”有时反而剥夺了学生反思的机会。
For a long time, many math teachers found that in the practice and test of primary school mathematics, there are common mistakes and mistakes sometimes and mistakes made by students. In the face of students’ mistakes, teachers usually explain it again and the students correct it again. Teachers can not help but sigh: done so many times, how wrong? The reason is, in fact, teachers and students in the process of correction, the students passively accept knowledge, did not experience the process of reflection, and did not really understand the error The reason, the correct understanding has not really established. Teachers too “worry about” sometimes deprived students of opportunities for reflection.
