三角函数是数型结合的关键性教学内容,主要是展现角和角之间的相互关系。通过学习培养学生数型转化思维,为学生今后的数学学习打下坚实的基础,所以具有重要的教学深意。本文主要介绍初中三角函数教学的现状,提出三角函数教学中的几点思考,主要目的是为了三角函数的教学提供理论参考,方便同行间教学方法间的交流,也为进一步提升学生三角函数学习效率做出学术贡献。
Trigonometric function is the key teaching content of the combination of numbers, mainly to show the relationship between angle and angle. Through studying and cultivating students 'thinking of numerical conversion, laying a solid foundation for students' future maths learning, it has important teaching meaning. This article mainly introduces the present situation of junior high school trigonometric function teaching and puts forward some thinking in trigonometric function teaching. The main purpose is to provide theoretical reference for the teaching of trigonometric function, to facilitate the communication between teaching methods among peers, and to further enhance students' learning efficiency Make academic contribution
