数学是一门具有严谨性、逻辑性、抽象性、实用性、科学性、延展性特点的学科,数学不是一门孤立的学科,掌握坚实的数学知识有利于学生其他理科科目的学习。高中数学是数学知识学习的一个上升期,但是数学学习依旧是很多学生的一个难点,高中数学分为三角函数、立体几何、不等式、函数等几个板块,三角函数作为一个独立的板块,和学生的生活距离较远,逻辑性较强,成为许多学生的学习难点,三角函数部分涉及公式、一般规律以及变形技巧等内容,内容比较丰富,并且和后续数学知识有着密切的联系。三角函数的学习是高中数学的一个重要组成部分,只有在熟练掌握三角函数的知识要点,才能保证学生后期数学学习顺利进行。本文浅论了高中三角函数教学中的不足和优化方式,希望对教师三角函数课堂教学有所帮助。
Mathematics is a discipline characterized by rigor, logic, abstraction, practicality, science, and scalability. Mathematics is not an isolated subject, and having a solid knowledge of mathematics is conducive to students’ study in other science subjects. High school mathematics is a rising period of mathematics knowledge learning, but mathematics learning is still a difficult point for many students. High school mathematics is divided into several functions such as trigonometric function, solid geometry, inequality and function. Trigonometry functions as an independent plate, and students Has a long way to go. It has become a learning challenge for many students. The trigonometric functions involve some aspects such as formulas, general rules and deformation techniques, which are rich in content and are closely linked with subsequent mathematical knowledge. Learning trigonometry is an important part of high school mathematics. Only when you master the knowledge points of trigonometric functions can we ensure the smooth progress of maths learning. This article discusses the shortcomings and optimization methods of high school trigonometry function teaching, hoping to help teachers trigonometry function classroom teaching.
