ABSTRACT

Purpose: The aim of this study is to investigate the knowledge of prospective physics teachers on capacitors and electric field lines. Sample: The study group consists of 45 prospective physics teachers, 31 of whom are female, 14 of whom are male, studying at a state University in Turkey.Design and methods: A descriptive model was selected as the method of the research. The data of the study were collected through a measurement tool and semi-structured interviews prepared by the research. The measurement tool consists of open-ended questions and drawings. The answers received from the prospective teachers were subject to descriptive analysis.Results: The findings showed that prospective teachers had sufficient knowledge of the definition, function, and structure of the capacitor. However, it was determined that there were difficulties in understanding the source of the loads in the capacitor plates. Furthermore, although they knew the definition and structure of dielectric, their knowledge of the function of dielectrics was not based on a scientific basis. The prospective teachers were unable to establish a connection between the dielectric and the electric field. They have also been found to confuse electric field lines with electric current and magnetic field lines. The prospective teachers often drew point charges for the electric fields between the capacitor plates. It has also been found that they think electric field lines are real.

摘要

目的：本研究的目的是调查未来物理教师对电容器和电场线的了解。样本：研究组由45名准物理教师组成，其中女性31人，男性14人，就读于土耳其一所州立大学。设计与方法：选择描述性模型作为研究方法。研究的数据是通过测量工具和研究准备的半结构化访谈收集的。测量工具由开放式问题和图纸组成。对来自未来教师的回答进行了描述性分析。结果：调查结果表明，未来教师对电容器的定义、功能和结构有足够的了解。然而，确定在理解电容器极板中的负载来源方面存在困难。此外，虽然他们知道电介质的定义和结构，但他们对电介质功能的认识并没有科学依据。未来的教师无法在电介质和电场之间建立联系。还发现它们会将电场线与电流和磁场线混淆。未来的教师经常为电容器板之间的电场绘制点电荷。还发现他们认为电场线是真实的。他们对电介质功能的了解并非基于科学依据。未来的教师无法在电介质和电场之间建立联系。还发现它们会将电场线与电流和磁场线混淆。未来的教师经常为电容器板之间的电场绘制点电荷。还发现他们认为电场线是真实的。他们对电介质功能的了解并非基于科学依据。未来的教师无法在电介质和电场之间建立联系。还发现它们会将电场线与电流和磁场线混淆。未来的教师经常为电容器板之间的电场绘制点电荷。还发现他们认为电场线是真实的。
