一、问题提出概念教学是高中数学教学的重要组成部分,学生对概念的掌握程度,在很大程度上影响了后续数学知识的学习。章建跃博士指出:概念教学要返璞归真,核心概念教学要舍得花时间,舍得花力气。问题是数学的心脏,只有设计符合学生的知识基础和认识规律的问题情境,让学生带着问题去思考、去探索、去交流,学生才能在不知不觉中认识概念,掌握概念的核心与本质。本文旨在借助《函数的概念》的教学过程,通过具体问题的设计,剖析问题设计的意图,对如何进行
First, the problem proposed Concept teaching is an important part of high school mathematics teaching, students grasp the concept of degree, largely affected the subsequent learning of mathematical knowledge. Dr. Zhang Jiangyue pointed out: concept teaching should be back to basics, the core concept of teaching should be willing to spend time, willing to spend energy. The problem is the heart of mathematics, only designed to meet the student’s knowledge base and understanding the law of the problem situations, so that students take the problem to think, to explore, to exchange, students can unconsciously understand the concept, grasp the core and essence of the concept . The purpose of this paper is to use “the concept of function” teaching process, through the design of specific problems, analysis of the design intent, how to proceed
