Research on the Construction of a Classroom Teaching Pattern for Primary School Mathematics Using Pictures as an Intermediary in the Picture-Reading Era

读图时代以图为中介的小学数学课堂教学样态构建,将助力于知识结构化、思维可视化、理解抽象化、推理具象化的小学生数学学习,有利于小学生情境化学习的发生,有助于小学生形成以图为中介的自我表达能力,有效发展小学生的协作能力,能够进一步发展小学生的视觉素养,实现小学生核心素养的高质量提升.以图为中介的小学数学课堂教学样态,包括了"课前以图为导,形成数学学习问题把脉;课中以图为引,完成已有认知的集体修正;课后以图为思,提升认知建构水平"等三个不断螺旋式循环提升的阶段性工作.

understanding,and concrete reasoning,help them form self-expression ability through pictures as an intermediary,effectively develop their collaboration ability,and further develop their visual literacy,which will surely realize high-quality improvement of primary school students’key compe⁃tencies.The classroom teaching pattern for primary school mathematics with pictures as an intermediary includes three stages of continuous spiral cycle improvement:the use of pictures as a guide before class to form problems for mathematics learning;the use of pictures as a guide in class to complete the collective correction of existing cognition;the use of pictures as a guide to improve the level of cognitive construction.
