三角函数内容是新课程标准中删减、变化最大的内容之一,作为教师,我们应当认真学习领会新课程标准和新教材,积极转变教学思想和研究教学方法,提高对素质教育的认识,笔者对高中数学新教材第四章进行了学习和比较肤浅的研究。本章三角函数,总共三单元,第一单元:任意角的三角函数;第二单元:两角和与差的三角函数;第三单元:三角函数的图象和性质。1新教材与旧教材的相异之处与旧教材比较,本章在时间安排和内容安排以及在教学要求上都有很大的改变。原来高中教材中三角函数及其相关的内
As a teacher, we should conscientiously study and comprehend the new curriculum standards and new teaching materials, actively change teaching thoughts and research teaching methods, and improve our understanding of quality-oriented education. The content of trigonometric functions is one of the most important contents of the new curriculum standards. The fourth chapter of the new high school mathematics textbooks for learning and comparative superficial research. This chapter trigonometric functions, a total of three units, the first unit: trigonometric functions at any angle; the second unit: trigonometric and differential trigonometric functions; the third unit: trigonometric functions of the image and nature. 1 new teaching materials and the old teaching material differences Compared with the old teaching materials, this chapter in the timing and content arrangements and teaching requirements have changed a lot. The original high school teaching materials in the trigonometric functions and their related
