初高中三角函数衔接教学的困境与突破策略研究

Research on Dilemmas and Breakthrough Strategies of Trigonometric Function Teaching for Junior-Senior High School Connection

摘要: 三角函数是初高中数学学习的核心内容。由于初高中课程标准对三角函数的教学侧重点存在差异，不同学段学生需要掌握的知识重点各不相同，致使学生在知识衔接环节面临阻碍，教师的教学工作也随之陷入相应困境。本文旨在剖析初高中三角函数衔接教学存在的现实困境，并据此提出具有针对性的突破策略。

Abstract: Trigonometric functions are the core content of mathematics learning in junior and senior high schools. Owing to the differences in the teaching focuses of trigonometric functions specified in the curriculum standards for junior and senior high schools, students in different learning stages are required to master distinct key knowledge points. This not only poses obstacles for students in the knowledge connection stage but also plunges teachers into corresponding predicaments in their teaching practice. This paper aims to analyze the practical dilemmas existing in the connection teaching of trigonometric functions between junior and senior high schools, and put forward targeted breakthrough strategies accordingly.
