新一轮课程改革的目标是提高教学的有效性,这对高中数学教师的教学能力提出了更高要求.从2009年起,云南省进行高中新课改,三年来的课改历程使我们深刻地认识到:必须用辩证的态度对待教学改革.在轰轰烈烈、大刀阔斧变革的同时,必须有理性的反思和科学的回归,才能真正做到革故鼎新,促进课堂教学改革的科学发展.作为一名数学教育工作者,笔者耳闻目睹了师生使用人教版数学教材的教育教学过程以及在教学中出现的种种现象与问题,感悟颇深. The goal of the new round of curriculum reform is to improve the effectiveness of teaching, which puts forward higher requirements on the teaching ability of high school mathematics teachers. Since 2009, To recognize that: we must use a dialectical approach to teaching reform in the vigorous, radical change at the same time, there must be rational reflection and scientific return, we can truly reform, promote the reform of the classroom teaching of science as a mathematical education Workers, I heard the teacher and student witnessed the use of PEP mathematics teaching materials and teaching process as well as in teaching all the phenomena and problems, profound understanding.
