高效课堂是以最小的教学和学习投入获得最大学习效益的课堂,其基本特征是“自主建构,互动激发,高效生成,愉悦共享”。衡量课堂是否高效,一要看学生知识掌握、能力增长和情感、态度、价值观的变化程度;二要看教学效果是通过怎样的投入获得的;三要看师生是否经历了一段双向激发的愉悦交往过程。基于上述理解,笔者认为要建构数学高效课堂,教师应着重做好以下几方面工作。 Efficient classroom is the classroom with the minimum teaching and learning input to get the maximum learning benefit. Its basic characteristic is “self-construction, interactive stimulation, efficient generation and pleasant sharing”. To measure the efficiency of the classroom, one depends on the students’ knowledge, ability to grow and the degree of change of emotion, attitude and values; 2 depends on the teaching effect is obtained through what investment; 3 to see whether teachers and students have experienced a two-way excitation of pleasure Communication process. Based on the above understanding, I believe that to build mathematical efficient classroom, teachers should focus on doing the following aspects.
