教师普遍认为,高三的数学复习课难上,它不具备新授课的新鲜感,又缺少专题课的成就感,更没有一个公认的基本的课堂教学范式。如何提高数学复习课教学的有效性?一直是教师感到困惑的问题,在新课标理念下,更成为数学教师的重要研究课题之一。经过多年的教学实践,笔者认为,合理恰当地运用变式教学,是提高数学复习课效率的有效途径之一。数学变式教学中的一题之“多”是指:一题多解、 Teachers generally believe that the senior high school mathematics review difficult, it does not have the freshness of new lectures, but also the lack of a sense of achievement of thematic classes, but not a recognized basic classroom teaching paradigm. How to improve the effectiveness of the teaching of mathematics review? It has always been a problem that teachers are puzzled. Under the concept of the new curriculum, mathematics teachers have become one of the most important research topics. After many years of teaching practice, I believe that a reasonable and appropriate use of variant teaching is an effective way to improve the efficiency of mathematics review classes. One of the questions in mathematical variant teaching “more” means:
