新课标中提出教师要重视验算教学,培养学生对计算结果进行估算和验算的习惯。实践证明:学生其实没有把验算当做一种内心的迫切需要,他们只有在“白纸黑字”铁的要求面前,在老师的强迫要求下,才会迫于无奈地运用规定的方法进行验算,因此培养良好的验算习惯势不可当。从教师改变教学观念,把验算教学落入实处;教师采用巧妙方法,帮助学生培养验算兴趣;家校合作,把验算进行到底这三方面着手,就小学数学中如何让学生培养良好的验算习惯做一些探讨,力求对一线的教师有所帮助。
The new curriculum proposed teachers should pay attention to checking teaching, training students to calculate the results of the calculation and checking habits. Practice has proved that students actually do not consider checking as a kind of urgent need of heart. Only when they are compelled by the teacher to be forced to check by the prescribed methods, can they be checked only in the face of the requirement of “black and white” iron It is not appropriate to develop good checking habits. Change teaching concepts from teachers to make sure that the checking and accounting teaching is practiced; teachers adopt ingenious methods to help students cultivate the interest in checking; home-school cooperation and the checking in the end are three aspects of how to enable students to develop good checking habits in elementary mathematics Some discussions, and strive to help front-line teachers.
