整体观视角下的课堂教学问题链设计——以人教版小学数学“解决问题”新授课的教学为例

The Problem Chain Design of Classroom Teaching Under the Perspective of Overall Teaching Conception——A Case Study of Elementary School Mathematics Teaching Themed on “Problem Solving”(PEP Edition)

课堂是一个整体,问题链也是一个整体,问题与问题之间要具有一定的层次结构、逻辑关系和先后顺序。问题链设计是对教学思路的进一步教学化设计,也使教学更具体、可操作性更强。设计好一节课的问题链框架,就能整体把握这节课的走向。解决问题教学的本质是数学建模,要依据其教学的本质和规律进行问题链的设计,以问题链的形式呈现解决问题教学的基本思路与方法,使教学更具启发性和探究性。

The classroom teaching is a whole,and the problem chain is also a whole.There should be certain structural levels,logical relations and sequence among problems.A good structural design of problem chain,which is the further integration of teaching ideas with more specifics and better practicality,contributes to the overall direction of one class.The essence of problem-solving teaching is mathematical modeling.The problem chain design is based on the essence and laws of the teaching itself.The basic ideas and methods of problem-solving eaching are presented by means of the problem chain,which is more enlightening and exploratory towards problem-solving teaching.
