三角函数是高中数学的重要内容,从学生的知识学习来看,学生有三角函数的知识基础,初中阶段学生学习过这部分内容,高中的学习可作为在原有认知基础上的有效延展.本文首先就这部分内容学生在学习过程中存在的问题进行分析,接着就如何进行教学的优化谈几点看法.一、学生三角函数学习误区1.学生缺乏对这部分知识学习的重视程度正因为三角函数这部分内容,学生在初中学习过,所以学生进入高中后,再遇到这部分知识,心理上有轻视,重视程度不
Trigonometric function is an important part of high school mathematics. From the point of view of students’ knowledge, students have the knowledge base of trigonometric functions. When junior high school students learn this part, high school learning can be used as an effective extension based on the original cognition. First of all, this part of the content of the students in the learning process of the existing problems analysis, and then talk about how to optimize the teaching to talk about several points. First, the students trigonometric function learning errors 1. The lack of students focus on this part of knowledge learning because of the triangle Function of this part of the content, students have studied in junior high, so students into high school, and then encounter this part of the knowledge, psychologically contempt, the degree of emphasis is not
