数学大师华罗庚说过,数学学习有两个过程:一是由薄变厚,二是由厚变薄。基于学习能力而言的学习是由薄变厚的过程,而基于学习任务而言的学习是由厚变薄的过程。即将凌乱的知识进行提炼、概括、总结,以便在大脑中形成思想、观点、方法和能力。因此,在课堂教学过程中,培养学生数学思维能力,促进学生有效掌握单元知识,是高中数学教学 Hua Luogeng math master said that there are two mathematical learning process: First, from thin to thick, and second, from thick to thin. Learning based on learning ability is a process of thinning, while learning based on learning task is a process of thickening. The messy knowledge is about to be refined, summed up, summarized, in order to form ideas, ideas, methods and abilities in the brain. Therefore, in the process of classroom teaching, cultivating students’ mathematical thinking ability and promoting students to effectively master the unit knowledge is the teaching of high school mathematics
