基于一元二次方程的模型观念培养研究——以人教版和苏科版初中数学教材为例
A Study on the Cultivation of Model Concepts Based on Quadratic Equations—Taking PEP and JSP of Junior High School Mathematics Textbooks as an Example

新课标对模型观念的培养提出了新要求，教师教学迎来了新的机遇与挑战。列方程解决问题是培养学生模型观念的重要内容之一，教材是教学的基础，而人教版和苏科版教材各具特色，研究通过对两版教材从内容设置、素材选取和课程难度三个维度进行比较，从而研究如何帮助学生感知数学建模的基本过程、培养模型观念，并对教师教学提出思考和建议。
The new curriculum puts forward new requirements for the cultivation of the concept of model, and teachers’ teaching ushers in new opportunities and challenges. Problem solving by equations is one of the important contents of cultivating students’ concept of model, and the textbook is the basis of teaching, while the textbooks of human-taught edition and the Jiangsu Science Press edition have their own characteristics. The study compares the two editions of the textbook in terms of three dimensions: the content setting, the selection of materials, and the difficulty of the curriculum, so as to study how to help students perceive the basic process of mathematical modelling, cultivate the concept of model, and to put forward reflections and suggestions for teachers’ teaching.
