《数学课程标准》(2011年版)强调:“教师教学应该以学生的认知发展水平和已有的经验为基础,面向全体学生,注重启发式和因材施教。”为此,数学教学既要考虑到数学本身的学科特点,又要遵循学生的认知规律,要从学生的已有知识水平出发,来让学生经历数学知识的建构过程和数学思维的发展过程。这种教学要在学生主体对要学习的数学学习内容进行亲自体验的基础上来实现,让学生在体验数学学习的同时,在情感过程,能力培养等多方面都能得到长足的发展。那么,如何遵循
The Standard for Mathematical Curriculum (2011 Edition) emphasizes: “Teachers’ teaching should be based on the level of cognitive development and experience of students, be aimed at all students, be heuristic and be taught in accordance with their aptitude.” Taking into account the characteristics of mathematics itself, but also to follow the cognitive rules of students, students must have the level of knowledge starting to allow students to experience the process of mathematical knowledge construction and mathematical thinking process. This kind of teaching should be realized on the basis of the students’ personal experience of the mathematics learning content to be learned, so that students can make great progress in many aspects such as emotional process and ability training while experiencing mathematics learning. Well, how to follow
