MPCK视角下的数学教学分析与设计——以小学“分数基本性质”为例

Analysis and Design of Mathematics Teaching from the Perspective of MPCK——Taking the“Basic Properties of Fractions”in Primary School as an Example

数学学科教学知识意指教师对数学学科知识、一般教学法知识以及有关学生数学学习知识的综合性认识,既是数学教师专业发展的核心,也是影响数学教与学的关键变量.以小学“分数基本性质”为例,从MPCK视角探讨数学教学分析策略,并由此设计教学,期待为数学教师专业发展与有效数学教学设计提供参考.

Mathematics pedagogical content knowledge(MPCK)refers to teachers’comprehensive understanding of mathematics knowledge,pedagogical knowledge and content knowledge.MPCK is not only the core of mathematics teachers’professional development,but also the key variable affecting mathematics teaching and learning.Taking the“basic properties of fractions”in primary school as an example,this paper discusses the analysis strategy of mathematics teaching from the perspective of MPCK,and designs teaching on this basis,hoping to provide reference for mathematics teachers’professional development and effective teaching design.
