1问题的提出初中数学教学中,概念获得的方式有两种,一种以概念形成方式获得,另一种是以概念同化方式获得.由于初中生的年龄、认知水平的特点,数学认知结构比较简单而具体,数学知识比较贫乏,在学习新的数学知识时,能作为同化新知识的已有知识相对较少,因此在教学中,大部分概念是以概念形成方式进行教学的.所谓概念形成是指人们对同类事物中若干不同例子进行感知、分析、比较和抽象,以归纳方式概括出这类事物的本质属性从而获得概念的方式.函数概念是初中数学教
A question raised in junior high school mathematics teaching, there are two ways to get the concept, one way to obtain the concept of formation, and the other way to obtain the concept of assimilation due to junior high school students’ age, cognitive level, mathematical cognition The structure is relatively simple and specific, mathematics knowledge is rather poor, and there is relatively little existing knowledge to assimilate new knowledge when learning new mathematics knowledge. Therefore, most of the concepts in teaching are taught by way of concept formation. Conceptual formation refers to the way in which people perceive, analyze, compare and abstract several different examples of similar things, summarizing the essential attributes of such things by inductive ways, and obtaining the concepts. The concept of function is that junior middle school mathematics teaching
