几年来,人们就小学数学改革进行了不懈的努力,对小学数学教学大纲、教材内容的改进,教学方法,课堂教学结构的更新,乃至教学中的具体环节都进行了深入的研究,取得了一些可喜的成绩。但是,我们也应该看到,建立在班级授课制基础上的众多教学改革,由于受到班级授课制的约束,这些改革本身就潜伏着三个主要障碍。从一定程度上来说,这些障碍制约着小学数学教学改革取得更大的突破性的进展,是造成目前教改工作徘徊不前的重要原因。因此, Over the past few years, people have been making unremitting efforts in mathematics reform in primary schools. They have conducted in-depth research on primary school mathematics syllabus, improvement of teaching materials, teaching methods, renewal of classroom teaching structure, and even specific aspects of teaching. Gratifying results. However, we should also see that many teaching reforms based on the class teaching system are bound by the class teaching system and these reforms inherently have three major obstacles. To a certain extent, these obstacles restrict the progress of mathematics teaching in primary schools to make greater breakthroughs, which is an important reason for the current education reform. therefore,
