《数学课程标准》中明确指出:数学教学活动必须建立在学生的认识发展水平和已有的知识经验基础上,教师应激发学生的学习积极性,向学生提供充分从事数学活动的机会,帮助他们在自主探索和合作交流的过程中真正理解和掌握基本的数学知识与技能、数学思想和方法,获得广泛的数学活动经验。因此,数学教学不能再是单一的、被动的接受和反复练习为主的方式。通过 “Mathematics Curriculum Standard” clearly states: Mathematics teaching activities must be based on the level of cognitive development of students and based on existing knowledge and experience, teachers should stimulate students’ enthusiasm for learning, to provide students with full access to mathematical activities to help them in In the process of independent exploration and cooperation and communication, we should truly understand and master basic mathematics knowledge and skills, mathematical ideas and methods, and gain extensive experience in mathematical activities. Therefore, mathematics teaching can no longer be a single, passive acceptance and repeated practice-based approach. by
