论文部分内容阅读
笔者近期研读了国内四个版本普通高中课程标准数字实验教材,现仅将不同版本教材各自特点归纳介绍如下,与数学同行交流。◆人教B版(1)突出通性、通法,揭示数学本质把基础数学中普遍实用的最基础部分、有普遍意义的通性、通法列为学习的重点。抓住这些重点内容,尽量为它们提供实际背景,反映其应用价值,努力揭示其发展过程和本质,使学生在经历数学概念、结论逐步形成过程的同时,体会蕴涵在其中的数学思想和方法。如在教材正文中适时安排栏目,揭示在数学问题解决过程中所蕴含的数学思想方法,又如将“待定系数法”作为一个小节的研究内容列入教材中。
The author has recently studied the four digital high school curriculum standards in China, and now only summarizes the characteristics of the different versions of the textbooks and communicates with their peers. ◆ People’s Education B Edition (1) highlights generality and common practice, and reveals the nature of mathematics as the most important part of basic mathematics. Grasp these key contents, try to provide them with practical background, reflect their application value, and strive to reveal its development process and essence, so that students experience the mathematical concepts and conclusions gradually formed the process, while understanding the mathematical ideas and methods contained in it. Such as the timely arrangement of columns in the text of textbooks, revealing the mathematics ideas and methods contained in the process of solving mathematical problems, and as a “section of the undetermined coefficient method” as a sub-section of the study included in the textbook.
