策略一:注重几何直观与教学本质的沟通几何直观是为更好的数学理解而服务的。我们不能只限于形式化的表达,要强调对数学本质的认识,否则会将生动活泼的数学思维活动淹没在“形式化的海洋里”。在低年级的一些基础课中,如“数的顺序”一课中,对前后的理解大可发挥画一画、动动手等形式,充分利用几何的直观性,使学生更具 Strategy One: pay attention to the communication between the geometric intuition and the nature of teaching Geometric intuition is to better mathematical understanding and service. We can not confine ourselves to formal expressions. We must emphasize the understanding of the nature of mathematics. Otherwise, we will submerge the vivid and mathematical thinking activities in the “formalized ocean.” In some basic courses of the lower grades, such as “the order of the numbers”, you can make use of the visual intuition of geometry and make the students have more
