核心素养视域下的跨版本教材对比研究——以“椭圆”为例
A Comparative Study of Cross-Version Textbooks from the Perspective of Core Literacy—Taking “Ellipse” as an Example

数学核心素养是学生数学学习能力的体现，也是培养学生分析解决思考认识问题和运用知识解决问题的重要支撑。椭圆作为高中数学的核心内容，对学生的数学素养的培养有着重要的作用。本研究依据2017年版《普通高中数学课程标准》，以现行的人教A版、北师大版、苏教版高中数学教材中“椭圆”相关内容为研究对象，采用内容分析法对教材编排体系、概念引入、“量”、数学文化渗透、信息技术应用5个方面在培养学生数学核心素养方面的相同点、不同点及其各自优势进行了对比研究。研究发现，在新课标指导下，这三本教材都充分体现了对学生数学核心素养的培养。
The core literacy of mathematics is the embodiment of students’ mathematics learning ability, and it is also an important support for cultivating students to analyze and solve cognitive problems and use knowledge to solve problems. As the core content of high school mathematics, ellipse plays an important role in the cultivation of students’ mathematical literacy. Based on the 2017 edition of the “General High School Mathematics Curriculum Standards”, this study takes the “ellipse” related content in the current high school mathematics textbooks of the People’s Education A Edition, the Beijing Normal University Edition, and the Jiangsu Education Edition as the research object, and uses the content analysis method to arrange the textbook. The similarities, differences and their respective advantages of the five aspects of the system, concept introduction, “quantity”, mathematical culture infiltration, and information technology application in cultivating students’ core literacy in mathematics were compared and studied. The study found that under the guidance of the new curriculum standard, these three textbooks fully reflect the cultivation of students’ mathematical core literacy.
