【摘要】：工科类机电专业知识的学习多数以三角函数为计算工具，同时三角函数由于公式多，变化多样，也是学生普遍感到困难的内容之一。因此，，要切实加强三角函数单元的教学研究。用科学的方法指导三角函数的教学设计，使教师在进行《三角函数》一章的教学之初就有一个整体规划，具体到每一单元、每一节课，都有针对性的教学目标。能根据具体情况安排教学内容，选择恰当的教学方法和教学媒体。在教学之初提供问题情境，使学生感到有必要重新认识三角函数的概念，并体会到三角函数在专业学习和实际生活中的广泛应用。在具体教学过程中，使知识前后联系，浑然一体，再加上方法得当，教师教的有味，学生学的有趣，自然会达到较佳的教学效果。本文分为两部分，第一部分以文献综述和分析为主，比较系统地阐述了教学设计的含义和理论基础；回顾了中职数学三角函数的相关研究、中职新大纲对三角函数的要求；以及三角函数教法的研究和分析。第二部分是案例分析，重点分析了三个案例：《角的概念的推广》，《任意角的三角函数》，《正弦函数的图像和性质》。
[Abstract]:Trigonometric function is the most important tool in the study of engineering mechanical and electrical specialty knowledge. At the same time, trigonometric function is one of the most difficult contents for students because of many formulas and varied changes. It is necessary to strengthen the teaching and research of trigonometric function units. Using scientific methods to guide the teaching design of trigonometric functions, so that teachers in the "trigonometric function" in the beginning of the teaching of a whole plan, specific to each unit, each class. Can arrange the teaching content according to the concrete situation, choose the appropriate teaching method and teaching media, and provide the problem situation at the beginning of teaching. Students feel it necessary to re-understand the concept of trigonometric function and realize the wide application of trigonometric function in professional learning and practical life. In addition, if the method is appropriate, the teacher will teach interesting, the student will learn interesting, will achieve the better teaching effect naturally. This paper is divided into two parts. The first part is mainly about literature review and analysis. It systematically expounds the meaning and theoretical basis of teaching design. This paper reviews the related research of mathematical trigonometric function in secondary vocational school and the requirements of the new outline of vocational school for trigonometric function; And the study and analysis of trigonometric function teaching method. The second part is a case study, focusing on three cases: "extension of the concept of angle", "trigonometric function at any angle", "Image and properties of sinusoidal function".
