教材旁白及其在高中数学教学中的运用

Textbook Narration and Its Application in Senior High School Mathematics Teaching

高中数学教材旁白作为教材结构的组成之一,虽然仅是一个"配角",但同样具有呈现知识、对正文进行诠释说明、提示核心内容以及启发学生思考等作用,具有丰富的教学功能。因而,有必要对教材旁白的内涵、教学功能以及教学的运用处理等问题进行探究,帮助学生通过对旁白的学习,获得对数学知识更为丰富的认识与理解,从而形成良好的数学核心素养。

As a part of the textbook structure of senior high school mathematics,textbook narration only plays a"supporting role",but it has rich teaching functions,such as presenting knowledge,interpreting and explaining the main part,prompting core contents and inspiring students'thinking.Therefore,it is necessary to explore the connotation,teaching functions and students'use and treatment of textbook narration,so as to help students to obtain further understanding of mathematical knowledge and form a good core mathematical literacy through the learning of textbook narration.
