论文部分内容阅读
函数是中学数学的重要内容之一,本单元复习的函数知识有内容多、联系厂、难度大三个特点。因而复习中应在系统整理(宜采用列表、填图、问答、选择、判别正误、辨析等方式进行)基本知识的基础上,加强与其它知识(数、式、形、方程和不等式)有机的联系和渗透,让学生正确理解概念的实质,掌握解题的基本方法,逐步培养独立处理以函数内容为主的综合问题的能力。由于教育部颁发了高中数理化两种要求的教学纲要。我们研究函数以初等方法为主,但不排斥利用导数研究函数的方法。下面按知识结构分六个部分谈谈如何复习。
The function is one of the important contents of the middle school mathematics. The function knowledge of this unit review has three characteristics: content, contact factory, and difficulty. Therefore, in the review, the basic knowledge of the system should be organized (appropriate list, map, question and answer, choice, judgment, error, discrimination, etc.) on the basis of strengthening the knowledge with other knowledge (number, formula, shape, equation and inequality) organic Contact and infiltration allow students to understand the essence of the concept correctly, grasp the basic methods for problem solving, and gradually develop the ability to independently deal with comprehensive problems that mainly focus on function content. Because the Ministry of Education has issued the syllabus for the two requirements of high school mathematics and chemistry. We study the function mainly based on the elementary method, but we do not exclude the method of using the derivative to study the function. Here are six parts to talk about how to review according to the knowledge structure.
