数学概念是数学基础知识的基础,数学概念教学十分重要.李邦河院士曾说“数学根本上是玩概念的,不是玩技巧,技巧不足道也!”认为以解题教学代替概念教学的做法严重偏离了数学的正轨,必须纠正.否则,学生在数学上耗费大量时间、精力,结果可能是对数学的内容、方法和意义知之甚少,“数学育 Mathematics concept is the basis of the basic knowledge of mathematics, mathematics concept teaching is very important .Li BangheAcademician once said ”mathematics is basically playing concept, not playing skills, skills are not enough too! " That the problem-solving teaching to replace the concept of teaching practice is serious Deviation from mathematics, must be corrected, otherwise, students spend a lot of time and energy in mathematics, the result may be little knowledge of the content, methods and meaning of mathematics,
