三角函数在初中阶段是一项重要的教学内容,也是中考的必考内容,因此要求学生对其有效掌握。教师在教学此部分知识的时候,需要加强对教学方法的研究,提升教学的有效性。基于此,本文针对当前初中数学三角函数的教学现状进行了分析讨论,然后在此基础上对三角函数的有效教学方法作了阐述,希望可以对初中数学教师起到一定参考借鉴之用。 Trigonometric function is an important teaching content in the junior high school stage, which is also a necessary part of the senior high school entrance examination. Therefore, students are required to master it effectively. When teachers are teaching this part of knowledge, they need to strengthen their research on teaching methods and enhance the effectiveness of teaching. Based on this, this paper analyzes and discusses the teaching status quo of the current junior high school math trigonometry function, and then elaborates the effective teaching method of trigonometric function on the basis of which, hoping it can be used as a reference for junior math teachers.
