A Study On Physics Preconception In Middle School And The Conversion Of It

Preconception is the opinion or conception about things and phenomena which is formed in everyday life by students before they are educated formally. Some of the preconceptions are consistent with scientific conceptions in certain limits and become the preparative knowledge for learning new scientific notion. But numerous preconceptions are inconsistent with scientific conceptions. These inconsistent opinions and conceptions exercise an negative influence on students' study and grasp of scientific conceptions, so we must pay attention to them.Based on literature search, this thesis starts from analyzing the causes and characteristics of preconceptions, and put forward a way to converse preconceptions to scientific conceptions according to educational psychology and guiding thought of the new teaching program. Then we apply it to the teaching of anticentripetal phenomena (or anticentripetal motion) for students who are in Grade 1 of senior school. Some methods are used for this research, including questionnaire survey, interview and experiment. At last, we analyze the result and flaws of the experiment. All our purpose is to provide a feasible way for the improvement of the physics teaching method in middle school.
