数学教科书是数学学科培养学生的媒介文本,例题教学是数学课堂教学的主要形式,是连接原理性知识与知识运用的中间环节,学生在自己能够独立解数学题之前,都必须经历解数学题这一活动环节,它也是学生学习数学入门阶段的问题。教师在备课、教学设计时认真设计例题教学,有利于促进初中学生数学概念、命题等原理性知识学习,提升初中学生应用数学的能力。一、初中数学例题教学的相关理论数学学科知识是一片浩瀚无际的海洋,数学以教科书文
Mathematical textbooks are the texts of students’ training in mathematics. The teaching of examples is the main form of mathematics classroom teaching. It is an intermediate link between the application of the principle knowledge and knowledge. Students must understand the math problems before they can solve math problems independently An activity link, it is also a problem for students to learn the introductory phase of mathematics. Teachers in the lesson preparation, teaching design carefully designed examples of teaching, is conducive to promoting junior high school mathematics concepts, propositions and other theoretical knowledge to enhance the junior high school students ability to apply mathematics. First, the junior high school mathematics problems related to teaching theory mathematical knowledge is an endless ocean, mathematics textbooks
