中学生几何光学前概念的统计与分析

Statistics and Analysis on Middle School Students’ Preconceptions of Geometrical Optics

以建构主义为指导,编制了包含20个题目的几何光学部分的调查问卷,通过对102名中学生进行问卷调查,然后对数据利用SPSS.10进行统计分析,揭示出学生在几何光学概念学习中普遍存在的各种前概念,并以此来了解学生光学概念建构的水平和层次.然后深入分析产生前概念的原因,以期为几何光学教学改革做一些基础性的工作,为今后进一步研究的开展奠定基础.

In this study select constructivism as guidance,prepared questionnaire containing 20parts of the subject geometrical optics,then carries out investigations on 102students’preconceptions.And then analysed the statistic data using SPSS.10.Revealed ubiquity preconceptions of students of the subject geometrical optics,and understand their level of physical concepts and layer construction through the analysis.Then in-depth analysis the reasons of the formation for the preconceptions,with a view to reforming the teaching of geometrical optics to do some basic work,lay the foundation for the future study.
