计算能力是一项基本的数学能力,计算能力是学生今后生活、学习和参加社会主义建设所必须的基本素质之一。提高学生的计算能力,有助于培养学生的数学素养,有助于培养学生解决问题的能力。但在现实的教学中,计算教学存在着明显的不足,比如:学生普遍存在轻视计算的态度,计算速度慢,准确率低,缺乏应有的推理、转化等数学思想和方法。同时教师在教学方面也同样抱有轻视的态度,认为只要把运算方法和运算步骤讲解具体了,学生就能做对 Computational ability is a basic mathematical ability. Computational ability is one of the basic qualities necessary for students to live, study and participate in the socialist construction in the future. Improve students’ computing ability, help to develop students’ mathematical literacy, help to develop students’ ability to solve problems. However, there are some obvious shortcomings in the teaching of computation in the teaching of reality. For example, there are ubiquitous mathematical attitudes and methods that are ignored by students, such as slow calculation, low accuracy, lack of due reasoning and transformation. At the same time, teachers also have a contempt attitude in teaching. They think that as long as the calculation methods and operation steps are explained concretely, students can do the right thing
