学习是一个认知过程,由于学生认知水平、理解水平的不同,解题中出现错误属正常现象。“错误”是课堂教学的宝贵资源,评析错误可以让学生认知更深刻、理解更透彻、成效更显著。下面通过几个教学案例,谈谈自己的认识。一、辨析错误,完善数学知识结构数学概念的理解、掌握和应用需要有一个过程,教师应适时辨析错因,以深化理解概念,完善数学知识结构。
Learning is a cognitive process. Due to different levels of students’ cognition and understanding, mistakes in solving problems are normal. “Error ” is a valuable resource in classroom teaching. To make mistakes in assessment can make students understand more profoundly, understand more thoroughly and achieve more remarkable results. Here are a few teaching cases to talk about my own understanding. First, to identify errors, improve the mathematical knowledge structure Mathematical concepts need to understand, grasp and apply a process, teachers should identify the wrong reasons in a timely manner to deepen understanding of concepts, improve the mathematical knowledge structure.
