高中数学课堂中问题串设置艺术探研

Exploration of the Art of Setting Problem Strings in Senior Middle School Mathematics Classroom

问题串是指按照某一特定规则与方法,精心设计而成的多个问题的集合。文章在分析问题串教学法的内涵与特征、问题串的类型与设置原则的基础上,从情境导入、知识生成、例题教学、课堂小结、复习课教学、规律教学等角度,探究高中数学课堂中问题串的设置策略,并提出问题串设计应注意的问题:充分结合学生已有经验、提高问题串设计能力、准确把握问题串教学的关键环节、增强问题串设计的灵活性,以此充分发挥问题串教学法的作用,促进课堂教学效率以及学生学习效率的提升。

A question string refers to a collection of multiple carefully designed questions based on a specific rule and method.On the basis of analyzing the connotation and characteristics of the problem string teaching method,the types and setting principles of problem strings,this article explores the setting strategies of teaching problem strings in senior middle school mathematics from the perspectives of situational introduction,knowledge generation,example teaching,classroom summary,review class teaching,and regular teaching,and proposes the issues that should be paid attention to in problem string design:fully combining students'existing experience,improving problem string design ability,etc accurately grasping the key links of problem string teaching and enhancing the flexibility of problem string design,in order to fully leverage the role of problem string teaching method,promote classroom teaching efficiency and student learning efficiency improvement.
