在小学阶段开展数学教学,学生主要通过触觉、视觉以及听觉接受数学信息,进而对其进行主动的组织和选择,将知识纳入到个人知识体系中。本文主要基于“建构式生态课堂”的小学中高年级学生数学表达能力培养进行分析和阐述,希望给予我国教育同仁以参考和借鉴。 At the elementary stage, mathematics teaching is carried out. Students mainly receive mathematical information through tactile, visual and auditory methods, and then take the initiative to organize and select them and integrate knowledge into the personal knowledge system. This paper is mainly based on “Constructivist Ecological Classroom ” in primary and secondary high school students Mathematical expression ability analysis and elaboration, I hope to give our education colleagues for reference and reference.
