三角函数是中学数学的重要内容之一,是学习中学后继内容和高等数学的基础.相对传统教材而言,统编新教材就“三角函数”这一章作了较大幅度的改动,这些变化正是体现新教材特点的地方,是教学中把握教材标高,落实素质教育,减轻学生负担,培养创新能力的关键所在.下面就三角这章相对传统教材而言谈一下新教材的特点.
The trigonometric function is one of the important contents of middle school mathematics, and it is the basis for learning the successor contents of higher schools and higher mathematics. Compared with traditional textbooks, the new text of the unified textbook has made a substantial change to the chapter “trigonometric function”. These changes It is the place that embodies the characteristics of the new textbooks. It is the key to grasping the elevation of teaching materials in teaching, implementing quality education, reducing the burden on students, and cultivating innovative abilities.
