物理师范生对电场概念理解的调查分析

研究学生对科学概念的理解,探究学生认知结构中的错误概念是近年来国际科学教育领域的重要课题.在广泛查阅国内外对电场概念理解研究的相关文献基础上,将定量研究与定性研究相结合,对物理师范生在学习电场内容时存在的困难以及困难的类型与根源进行了实证研究,从不同角度对学生的困难及其根源进行了分析与讨论,并提出了改进电场单元的教学建议.

Investigation and analysis on understanding the concept of electric field for normal school students

It has been an important topic to study students’understanding of scientific concept and to probe students’misconceptions of cognitive structure in international science education research.Many of the current research in physics education have been concerned on students’understanding of force concept and circuit and few pedagogical studies on the concept of electric field.On the basis of a comprehensive review and evaluation of the research work on science education,the paper explores students’learning difficulties of electric field,analyzes their types and reasons.Proposes improved suggestions on teaching and learning of electric field.
