高中数学教科书助读系统分析及其对生长教学的启示——以2019年人教A版为例

Analysis of reading aid system in high school mathematics textbooks and its enlightenments to growth teaching:Taking the 2019 PEP Edition A as an example

为提高高中数学教科书在教学中的使用效率,结合数学学科特色探究助读系统在教科书中的主题分布情况.结果表明:助读系统在越抽象的章节中分布数量越多,且图文并茂;助读系统主要通过引导性的语言或任务激起学生的学习兴趣和探索欲望,并借助详细的解析类要素帮助阅读者突破阅读难点;助读系统通过详略得当的布局及具有不同作用的构成要素帮助学生建构教科书中的知识体系,并衍生出更深层次的知识.由此得出,合理地使用助读系统,有利于彰显生长教学育人味浓、生长性明和思维力强的本质特征,从而更好地落实生长教学理念,因此教师在教学时要注重明晰知识的生长性、善用启发式教学、传播人文价值.

In order to improve the application efficiency of high school mathematics textbooks in teaching,combined with the characteristics of mathematics discipline,this paper explored the topic distribution of reading aid system in textbooks.The results show that the more abstract the chapters are,the more reading aid systems are distributed,with the excellent texts and illustrations.The reading aid system mainly arouses students′learning interest and exploration desire through guided language or tasks,and helps readers break through reading difficulties with the aid of detailed analyzing elements;the reading aid system helps students construct knowledge system in textbooks and derive deeper knowledge through the proper layout and the constituent elements with different functions.It can be concluded that,the rational use of the reading aid system is conducive to highlighting the essential characteristics of growth teaching,which is rich in education,clear in growth and strong in thinking,so as to better implement the growth teaching concept.Therefore,teachers should pay attention to clarifying the growth of knowledge,making good use of heuristic teaching,and spreading humanistic value in teaching.
