数学教学有两条线,一条是明线即数学知识,一条是暗线即数学思想方法.目前的数学教学有重“明”轻“暗”的现象,即重数学知识的传授,轻数学思想方法的传授.而数学思想方法是数学的精髓,是学生形成良好认知结构的纽带,是知识能力的桥梁,是培养学生良好的数学观念和创新思维的关键.因此在三角函数教学过程中应充分挖掘数学知识背后的数学思想方法,重视数学思想方法在各个教学环节中的渗透,让学生领悟其价值,培养应用的意识.下面分析几点在三角函数教学中
There are two lines of mathematics teaching. One is the open line that is knowledge of mathematics, the other is the dark line that is the method of mathematics. The current mathematics teaching has the phenomenon of “brighter”, lighter “dark”, ie, imparting knowledge of heavy mathematics, light The teaching of mathematics thinking methods. Mathematical thinking and methods are the essence of mathematics. They are the bond for students to form a good cognitive structure. They are the bridge of knowledge and the key to cultivating students’ good mathematical concepts and innovative thinking. The mathematical thinking methods behind mathematics knowledge should be fully tapped, and the penetration of mathematics thinking methods in all aspects of teaching should be emphasized. Students should be able to comprehend their value and cultivate their awareness of application. The following analysis of several points in trigonometric teaching
