Exploring the Value of Civic Education in High School Mathematics—An Example Is “Extending the Number System and Complex Number Concept”

数学是中学阶段重要课程，其学科育人价值具有不可替代性。课程思政是学科教学落实立德树人根本任务的方法与途径，高中数学教师通过备课、课堂教学等活动，将学科课程与课程思政相融合，实现知识传授与价值引领的有机统一，最终形成“三全育人”的新格局。拟以普通高中教科书(2019人教A版)必修第二册为例，从挖掘课程内容、选择思政策略等维度，认识课程思政育人的特殊价值、破解制约实施课程思政的典型问题，结合“数系的扩充和复数的概念”尝试发现实施数学课程思政育人价值最大化的有效途径。Mathematics is an important subject in high school, and its educational value is irreplaceable. Civic curriculum is the method and way to carry out the basic task of moral education in the teaching of the subject, and high school mathematics teachers integrate the subject curriculum with civic curriculum through lesson planning and classroom teaching activities, realize the organic unity of knowledge transmission and value guidance, and form a new pattern of “three-whole education”. We will take the second compulsory book of the general high school textbook (2019 human education A version) as an example, from the dimensions of mining course content, choosing the strategy of thinking, recognizing the special value of the course of thinking and educating people, and solving the typical problems that restrict the implementation of the course of thinking and educating people, and try to find the effective ways to implement the value of the mathematics course of thinking and educating people in the context of the expansion of the number system and the concept of complex numbers. We will try to find an effective way to maximize the value of the mathematics curriculum.
