小学数学知识的系统性强,前后知识、新旧知识是一个互相联系的整体。因此,教师要从数学知识结构的整体出发,引导学生会用“联系”的方法解决数学问题。那么,我们教师在教学实践中如何引导学生运用“联系”的方法解决数学问题呢?一、运用前后知识“联系”的方法解决数学问题小学数学教材每一个知识点都处在一定层次的系统中,这样无论从纵向的还是从横向的联系上都出现了教学知识上的先后问题,即有起始教材和后继教材之分。教师在
Primary mathematics knowledge system is strong, before and after the knowledge, old and new knowledge is an interconnected whole. Therefore, teachers should start from the overall structure of mathematics knowledge, and guide students to solve math problems by using “connection ” method. So how can our teachers guide students to solve the math problems by using the method of “connection” in the teaching practice? First, to solve the math problem by using the knowledge of before and after “connection”. Every knowledge point of elementary school is at a certain point Level system, so that no matter from the vertical or horizontal linkages have appeared on the teaching of knowledge has the problem, that is, there are starting materials and subsequent teaching materials points.
