The Research Of Physics Demonstration Experiment Teaching In The High School Of Yunnan Province According To Constructivism

Physics demonstration experiments are an important part of classroom teaching.Effective teaching is helpful for students to observe and summarize the laws of physics demonstration experiment.It can improve student's ability to understand and explore the world.However,nowadays,demonstration experiment teaching in high school physics often ignores the developments of students' abilities which include observation,hands-on practice and cultivation collecting information and so on.Therefore,the building of effective physics demonstration experiment teaching mode and strategy become a subject that is worthy to research further in physics demonstration experiment.In this paper,based on the analysis of the constructivism theory,combining with the actual situation of physics demonstration experiment teaching in the high school of Yunnan province,some suitable teaching strategies are proposed as follows:The author made a survey about present situation of demonstration experiment teaching in the high school physics of Yunnan province,through the ways of student'questionnaire and teacher' interview.It can find that most of teachers and students pay attention on the demonstration experiment;they believed that the demonstration experiment is an indispensable part of the physics teaching.At the same time,most students are eager to prepare experiment content and demonstrate by themselves,but the teachers are often worrued about the class will out of control,they finish all of the demonstration experiment separately,and it makes students get into a passive state.Combining with the actual situation of physics demonstration experiment teaching in the high school of Yunnan province and the constructivism theory,the author put forward a point of view which allows students to complete the demonstration experiment by themselves,and analyze the feasibility of this idea from the goal of high school “physics course standard” and students' knowledge ability level;Combining with the cognitive characteristics of senior high school students in Yunnan province and the ease of demonstration experiment,put forward some strategies: independent demonstration experiment,team demonstration experiment,teachers and students complete experiment together;Finally,the “weightless” as an example of create situation,make a comparison about the two experiment models which perform experimental demonstration of several parts.By doing this can cultivate students' learning enthusiasm,so as to improve the teaching effect of demonstration experiment.Based on the constructivism theory and the students as "performer" demonstration experiment teaching model,The author design three teaching cases,which are "Lenz's law","total reflection",and "several common magnetic fields ".In the design process of cases,from the angles of theory and practice,clear about the respective tasks and labor of student and teacher in front of the experiment,experiment,experiment after,It emphasis on the construction of thinking that student is the master of learning and teachers help students learn knowledge.
