近两年来,不断有专家和教师对课改中一些过犹不及的现象进行讨论,提出质疑和中肯的建议,如算法多样化的优化问题、小组合作学习的有效组织、教师引导者作用的正确发挥等,小学数学的课程改革进入了一个“冷思考”的阶段。冷思考潮流出现的原因主要有两点:一是专家和教师在课改中不断实践和反思;二是新世纪以来,美国等西方国家一改过去妄自尊大的态度,出现了“向东方学习”的热潮,使国人重新审视自己的数学教学。这些冷思考对纠正课改中的一些偏差,推 Over the past two years, experts and teachers are constantly discussing some problems that have never been done in the course of curriculum reform. They have raised questions and pertinent suggestions, such as the optimization of algorithm diversity, the effective organization of group cooperative learning, the correct role of teacher guides, etc. The elementary mathematics curriculum reform has entered a stage of “cold thinking”. There are two main reasons for the cold trend of thinking: First, experts and teachers continue to practice and reflect on the curriculum reform. Second, since the new century, the United States and other western countries have changed their arrogant attitude toward the past and emerged in “learning from the East.” Craze, so that people re-examine their own mathematics teaching. These cold thinking to correct some of the deviations in the curriculum reform, push
