在现实的数学课堂教学中,教师常常费尽心思地创设各种各样的问题情境,试图让学生亲身经历数学化的过程,像数学家一样地发现新知识.尽管教师的初衷是美好的,但看似热闹的数学活动情境,往往存在针对性不强、解释力不足或操作活动形式化等问题.究其原因,共同缺陷在于脱离了学生的基本数学活动经验.鉴于此,本文拟结合经典数学原理——数学归纳法一堂课的教学设计,探索数学课堂中,如何丰富学生的基本数学活动经验,以实现有效的数学化.
In the reality of mathematics classroom teaching, teachers often try their best to create a variety of problem situations in an attempt to let students experience the mathematical process, like mathematicians to find new knowledge.Although the original intention of teachers is good, However, the seemingly lively situation of mathematics activities often has such problems as lack of pertinence, lack of explanatory power or formalization of operational activities, etc. The common defect lies in the fact that it deviates from the students’ experience in basic mathematical activities.In view of this, Mathematical Principles - Mathematical Induction A lesson in the teaching design, to explore the mathematical classroom, how to enrich students’ basic mathematical activities in order to achieve effective mathematical.
