核心素养视域下的数学教学内容分析与教材呈现内容比较——以“认识人民币”为例

Analysis of Mathematics Teaching Content and Comparison of Teaching Materials from the Perspective of Core Competencies——Taking“Understanding RMB”as an Example

“认识人民币”是集多种数学核心素养于一体的重要教学内容.从小学数学核心素养框架对“认识人民币”教学内容分析,并比较分析人教版、苏教版、北师版和西师版中相应内容发现:“认识人民币”的教学内容中数学核心素养主要体现在数学概念、数学命题、数学抽象、数学建模、运算能力、转化思想、文化底蕴、思考自学和创新实践9个方面;4个版教材中“认识人民币”的内容呈现特点是重视情境化教学和学生经验理解、数学习题的背景单一、实践操作性强、关注文化渗透.对“认识人民币”教学应立足数学认知的培养,重视数学思想的形成,显化数学能力的发展,立足个人发展的取向.

ion,mathematical modeling,arithmetic skills,transformation ideas,cultural heritage,thinking and self-learning,and innovative practice.The content of“Understanding RMB”in the four editions of textbooks is characterized by emphasizing on contextualized teaching and students’experience and understanding,the single background of mathematical exercises,the strong practical operation,and focus on cultural penetration.The teaching of“Understanding RMB”should be based on the cultivation of mathematical cognition,attach importance to the formation of mathematical ideas,manifest the development of mathematical abilities,and be based on the orientation of personal development.
