核心概念学习进阶的理论建构及实证研究——以“几何光学”为例

Theoretical Construction and Empirical Research on the Learning Progressions of the Key Conceptions——Taking Geometrical Optics for Example

核心概念和学习进阶的提出,对基础教育阶段教学具有重要意义。为此,以几何光学为例,构建几何光学核心概念进阶框架,设计跨年级的几何光学调查量表,并对小学、初中、高中共832名学生进行调查。结果表明:对几何光学核心概念的理解,小学生主要处在经验层级和映射层级,初中生和高中生均主要处在关联层级,且初中生和高中生对几何光学核心概念的理解无显著差异。

The proposal of key concepts and learning progressions is of significance to the elementary education teaching. By taking geometrical optics for example, the author constructed the framework of geometrical optics＇ key concepts, designed the geometric optics questionnaire cross grades, and surveyed 832 students in primac~ schools, junior high schools and senior high schools respectively. Results show that , for the understanding of the key concepts of geometrical optics, primary school students are mainly in experience level and mapping level, jun- ior high school students and senior high school students are mainly in relation level, and there is no significant difference in junior and senior high school students＇ understanding.
