改革开放以来,尤其是20世纪90年代以后,中国数学教育的理论与实践无论在研究论题的深化方面和研究范围的拓展方面都获得了可喜的成绩并呈现出许多新的特点.但是,一直以来困扰数学教学的低效率问题却仍没有得到很好的解决.近读天津师范大学王光明教授的新作《数学教学效率论》, Since the reform and opening up, especially since the 1990s, the theory and practice of mathematics education in China have both gratified achievements and many new features in both the deepening of research topics and the expansion of research scope. However, However, the problem of inefficiency that plagued mathematics teaching is still not well solved.Recently, Professor Wang Guangming, a professor at Tianjin Normal University, put forward the theory of math teaching efficiency,
