1对数学概念形成导入方式的认识所谓概念形成,是指用归纳、概括,从观察到的一类事实中概括出有关的一类事物的共同点,得出一般规律的过程,或者通过分析问题、解决问题,在探索解决问题的途径中获得概念的形式。例如,在初中阶段学习有理数的概念时,我们可以通过如下的步骤对“有理数”概念的形成进行教学:让学生列举学过的数一引导学生对这些数进行分类→在正确分类的基础上给出有理数的定义→通过正反 1 understanding of the formation of the mathematical concept of the formation of the introduction of the so-called concept of the formation of the so-called concept refers to the use of induction, generalization, from the observation of a class of facts that summarize the commonalities of a class of things to come to the general law of the process, or by analyzing the problem , Solve the problem, get the concept of the form in the way of exploring the solution to the problem. For example, when learning the concept of rational numbers in junior high school, we can teach the formation of the concept of “rational numbers” by: Letting students enumerate the numbers learned 1. Sorting these numbers into categories → Basis for proper classification On the definition of rational numbers → positive and negative
