在应试教育背景下,小学数学教师主要采用机械的、大量的题海战术,来不断地训练小学生的计算能力。由于这种方法枯燥,而且低效,使得许多学生在做题中渐渐失去了对数学计算的兴趣。随着新课程改革的深入,又存在部分小学数学教师倾向于让学生使用多样化的方式进行解题,让学生任意发挥,但是实施的效果不佳。如何才能有效地提高小学生的计算能力是每一位小学数学教师亟待解决的问题。本文从笔者教学经验出发,对在新课程背景下如何有效地提高小学生的计算能力进 Under the background of exam-oriented education, primary school mathematics teachers mainly adopt mechanical and massive questions of sea tactics to continually train primary students’ computing abilities. Because of the boring and ineffective approach, many students are gradually losing interest in math calculations. With the deepening of the new curriculum reform, there are also some primary school mathematics teachers tend to allow students to use a variety of ways to solve problems for students to play, but the implementation of poor results. How to effectively improve the computing power of pupils is a problem that every primary school mathematics teacher needs to solve urgently. Based on the author’s teaching experience, this paper analyzes how to effectively improve the computing power of pupils under the new curriculum background
