数学的学习的真正开始是从学习数学新概念开始的.在数学新概念的学习上,学生对它的认同常常基于对描述概念文字的记忆,理解上只停留在浅层次的水平上,对它的产生合理性认识不足、理解不透.因此,作为数学教师不能忽视对数学新概念教学的设计.数学概念的生发应当努力呈现出一种原生态的知识被发现的过程,以学生原有的知识基础 The real beginning of the study of mathematics begins with the new concept of mathematics.In the study of the new concept of mathematics, students’ recognition of it is often based on the memory of describing the conceptual words, only on the shallow level of understanding, Therefore, as a mathematics teacher can not ignore the design of the new concept of mathematics teaching.Mymatical concepts should strive to show a process of discovery of the original ecological knowledge, to the original students Knowledge base
