Investigation On The Concept Of Physics Electromagnetism In Senior High School Students

Electromagnetism, as a important branch of physics, is hard and difficult in high school physics learning. Lack of related everyday experience and lack of direct observation may cause mistakes during studying, and make it more difficult to learn electromagnetism. It is helpful if teacher can play a driving role to help students construct their science concept framework. Therefore, it is important to examine electromagnetic preconceptions effectivelyThis research uses questionnaire methodology to analyze students’ understanding of electromagnetic preconceptions, different factors that may affect electromagnetism studying, and if there is any chance to improve current teaching process. This paper draws on the CSEM electromagnetic preconception questionnaire abroad, according to the current situation of domestic high school students to modify and design our questionnaire. We choose the students in Xiamen Shuangshi middle school in Fujian province and Nanjing first middle school in Jiangsu province as the subjects. The investigation on different grade, different gender, different regions, different level of students. We draw the following conclusion after data analysis:1. Domestic students’electromagnetism learning focus on the phenomenon and ignore the principle.2. Students have only a few electromagnetic preconceptions before their high school study. And most concept framework of students are construct in the class. if an error in process of conceptual construction, will establish the physical model error3. Grade is the only one that affects students’ level. Main effect of gender and the interaction between gender and grade are both weak.Based on the results and analysis of the research, the author points out that focusing on general conception teaching, make good use of students’ preconception knowledge, and focusing on experiments are notable points.
