突出教材的使用,并以教材为基础进行二次开发,为学生的数学学习活动提供广阔的探究素材,促进学生数学能力的发展。因此,教师需要从教学思想、教学方式变革、生本课程等基本理念角度,在教学中逐步从教教材转变到用教材的,通过对教材的二次开发,极大的加深学生对数学知识的学习和理解能力,拓展数学思维,学习数学思想。 Highlight the use of textbooks, and secondary development of teaching materials as the basis for the students to provide a broad study of mathematics learning materials to promote the development of mathematical ability of students. Therefore, teachers need to change from teaching materials to teaching materials from the perspective of teaching ideas, teaching methods, and students ’basic concepts. Through secondary development of teaching materials, teachers should greatly deepen students’ learning of maths knowledge And understanding ability, expand mathematical thinking, learning mathematics.
