小学数学教学的任务,可以概括成三个方面:第一是使学生掌握数学基础知识;第二是培养学生有数学基本能力;第三是思想品德教育。对此,我们须有全面的认识。培养学生的基本能力,主要指计算能力,初步的逻辑思维能力和空间观念、初步的空间想象能力。我们将在第四、五、六讲里分别讲有关内容。现在先来讲讲计算能力的培养问题。《大纲》对计算能力的要求是“能够正确地、迅速地进行整数、小数、分数四则计算”,“同时还应注意计算方法合理、灵活”。首先要求计算正确无误。在 The task of primary school mathematics teaching can be summarized into three aspects: first, to enable students to master the basic knowledge of mathematics; second, students should have the basic ability of mathematics; third, moral education. In this regard, we must have a comprehensive understanding. The basic ability of students, mainly refers to the calculation ability, the initial logical thinking ability and space concept, the initial spatial imagination. We will talk about the contents in the fourth, fifth and sixth lectures respectively. Now let's talk about the training of computing power. The “outline” requirement for computing power is “to be able to correctly and quickly make integer, decimal, and fractional calculations” and “at the same time pay attention to the reasonable and flexible calculation method”. First calculate the correct calculation. in
