建模：一种有效的建构性学习方式

建模作为一种建构性学习方式，可促使学习者根据先前的知识经验，使用所给与的物件和工具，来探究当前情境，建构起对当前情境的理解，并将自己的这种理解表达出来，从而可促进学生对知识的深层理解和灵活应用。建模分为探究性建模和表达性建模2种形式，包含定量、半定量和定性3种抽象水平。在教学中，教学者可根据学生的发展水平，提供适当的支持，帮助学生展开不同形式、水平的建模活动。

Modeling As An Effective Way Of Constructive Learning

Modeling as a constructive learning way can engage students in understanding some phenomenon and expressing their representation to them by exploring the situation through some given objects and tools, so it can enhance students' deep understanding and flexible application of knowledge. Modeling includes exploratory mode and expressive mode, and can be divided into three different levels: quantitative, qualitative, and semi-quantitative modeling. Instructors can help students engage in some modeling activities according to their developmental levels and in some adequate supports.
