一、教学内容分析本节是苏教版高中数学必修四§1.1任意角、弧度第一课时在《课程标准》中:三角函数是基本初等函数.本节课是三角函数这一章里重要的一节课,它是本章的基础.本节主要是通过问题引导学生自主探究任意角的生成过程,从而很好理解终边相同角之间的数量关系.二、学生学习情况分析学生在初中阶段已经学习了一些角,如锐角、直角、钝角、平角、周角.如何解释生活中的一些现象,如体操、跳水中的“转 First, the teaching content analysis This section is the Jiangsu education high school mathematics required four §1.1 arbitrary angle, radian first class in the ”course standard": trigonometric function is a basic elementary function. This lesson is a trigonometric function in this chapter is important A lesson, which is the basis of this chapter. This section is mainly to guide students to explore the creation process of arbitrary angle through problems, so as to better understand the quantitative relationship between the same side of the end. Second, students’ learning situation analysis students in junior high school Some corners have been studied, such as acute angles, right angles, obtuse angles, flat angles, and corners. How to explain some phenomena in life, such as gymnastics, diving
