高中数学“三角”涉及的函数知识和数学公式比较多,内容相对比较灵活,向来是学生学习数学的薄弱环节。这一部分知识又是高中数学课程的重要组成部分,主要是因为它蕴含着丰富的函数知识和数学思想方法,通过对三角内容的学习,有利于提高学生的计算能力和空间想象能力,对培养学生的立体思维具有重要作用。但纵观高中数学三角内容教育学的实践发现,大多数课堂教学停留在表面,没有对三角内容进行深入分析,使得三角内容的真正内涵没 High school mathematics “triangle ” involves more functional knowledge and mathematical formulas, the content is relatively flexible, has always been the weak link in the students learning mathematics. This part of knowledge is an important part of high school mathematics curriculum, mainly because it contains a wealth of functional knowledge and mathematical thinking methods, learning through the triangle content, is conducive to improving students’ computing power and spatial imagination, training students Three-dimensional thinking has an important role. But looking at the practice of pedagogy in high school mathematics triangle contents, most of the classroom teaching stays on the surface without analyzing the triangle contents in depth, making the true connotation of the triangle contents
