“数学的精神和本质在于它的思想和方法”.正是基于这种指导思想,要特别重视在例题教学中的数学思想的渗透,并用于指导解题教学.基本的数学思想是人人能懂、处处有用,这是通性通法,学生掌握了它就掌握了学习数学的“万能”钥匙,因此,在例题教学中,在加强基础知识教学的同时,沿着数学思想这条主线把力气花 “The spirit and essence of mathematics lie in its thoughts and methods.” It is based on this guiding principle that special attention should be paid to the infiltration of mathematical ideas in the teaching of examples and to guide the teaching of problem solving.The basic mathematical thinking is that people People can understand, everywhere useful, this is the general method, students master it mastered the learning of mathematics “universal” key, therefore, in the case of teaching, while strengthening the teaching of basic knowledge, along the mathematical thinking This main line of effort to spend
