以问题解决知识推理路径为核心的问题再设计——以初中数学为例

Problem Redesign Centered on Reasoning Paths of Problem Solving Knowledge—Taking Junior High School Mathematics as an Example

摘要: 高质量教学问题能促使学生在问题解决的过程中不断地思考和分析，综合运用已有的知识进行知识建构，对教师教学和学生思维能力发展皆有所裨益。问题设计是形成高质量问题的基础，但创设新问题具有一定的门槛，对一线教师来说难度大，效率低。为此，本文构建了以问题解决知识推理路径为核心的问题再设计流程，并以初中数学几何部分内容为例进行实操，旨在为教师提供一种能根据实际学情和教学目标知识点对原有问题再设计生成符合教学需要、具有针对性的高质量问题的方法指导。

Abstract: High-quality teaching problems can motivate students to think and analyze continuously in the process of problem solving and construct knowledge by integrating and applying existing knowledge, which is beneficial to both teachers’ teaching and the development of students’ thinking ability. Problem design is the basis for the formation of high-quality problems, but the creation of new problems has a certain threshold, which is difficult and inefficient for front-line teachers. For this reason, the paper constructs a problem redesign process centered on the reasoning path of problem solving knowledge, and takes the content of junior high school mathematics geometry as an example for actual practice, aiming to provide teachers with a methodological guide to redesign the original problems according to the actual learning situation and the knowledge of the teaching objectives and generate high-quality problems that meet the needs of teaching and learning and have a targeted approach.
