新一轮基础教育课程改革所构建的新课程体系,在课程功能、课程理念、课程目标、课程内容、课程评价等方面都有较大的突破和创新,它要求教师不仅要做课程的实施者,更要做课程的研究者和开发者。基于此要求,我们一线数学教师在准确把握教材的同时,应对课程资源进行适度的整合和开发,对课本中的例题进行适当的变式和延伸,让学生在不同的情境应用中加强对数学知识本质特征的理解,从而促进学生对数学
The new curriculum system constructed by the new round of basic education curriculum has great breakthroughs and innovations in curriculum functions, curriculum concepts, curriculum objectives, curriculum contents, curriculum evaluation and so on. It requires teachers not only to be the implementers of the curriculum , But also to do the course researchers and developers. Based on this requirement, while front-line mathematics teachers grasp the teaching materials accurately, we should moderately integrate and develop the curriculum resources, make appropriate variations and extensions to the examples in the textbooks so that students can strengthen their understanding of mathematics in different contextual applications The understanding of the essential features thus promotes students’ understanding of mathematics
