在口算教学中,有人认为最主要的任务是教给学生计算的方法,在大量的练习之后帮助学生形成熟练的运算技能,谈不上什么发展思维,即使有也是冰山一角,微乎其微。其实不然,口算教学,除了发展学生的计算能力,完全可以与数学思维同行。下面,笔者结合自己的教学实际谈几点看法。一、展开获得口算方法的过程,提高学生思维的探索水平1.在操作中理解算理,发展思维的建设性比如一年级上册有“9加几”这节口算教学课,在学习这部分知
In oral education, some people think that the most important task is to teach students to calculate the method, after a large number of exercises to help students develop proficiency in computing skills, not to mention what the development of thinking, even if it is the tip of the iceberg, minimal. In actual fact, oral arithmetic, in addition to the development of students’ computing power, can peer with mathematical thinking. The following, I combine my own teaching to talk about the actual point of view. First, expand the process of obtaining the oral calculation method to improve the level of exploration of students thinking 1. Understand the operation in the operation, the development of constructive thinking For example, the first grade book with “9 plus a few” this section count the teaching class, learning this Part of the knowledge
