提高低年级学生的计算能力和计算效率,并不是一朝一夕的事,需要一个长期复杂的教学过程。平时,教师要重视学生错题的收集和整理,分析错误的思想根源,在教学中有针对性地设计练习题,尤其加强易错题的比较性练习,提高学生计算的正确性。 Improving the computing power and computational efficiency of lower-level students is not an overnight success and requires a long and complicated teaching process. In normal times, teachers should pay attention to the collection and arrangement of mistakes of students, analyze the wrong ideological roots, and design exercises in the teaching in a targeted manner. In particular, they should strengthen the comparative practice of error-prone questions and improve the correctness of student calculations.
