Design And Practice Of Visualization Teaching In Junior Middle School Physics Experiment

Under the new standard,the junior middle school physics teaching reform requires teachers to change teaching methods.Problems in the traditional physical experiment teaching exists,need to change the status quo.The appearance of visualization theory and technology provides technical support and development opportunity for the reform of teaching methods of physics experiment in junior high school.In junior high school physics experiment teaching,how to apply the visualization teaching to break through the difficult point has the feasibility and certain research value.First of all,the research status of visualization and visual teaching and visualization teaching in junior middle school physics experiment at home and abroad is understood through the literature method to provide theoretical support for the next research.The second is the investigation of visualization teaching of physics experiment.Through the questionnaire survey of grade eight students in our school,to understand the demand of physical experimental visualization.Taking the physics experiment teaching competition in Guangxi middle and primary schools as an example,the visual direction of the experiment was found by combing the relevant cases.Taking the experiment of "Studying the Influencing Factors of Sliding Friction Force" as an example,the comparative study was conducted on three different visualization methods: DIS digital experimental system,mobile phone screen projection and improvement of traditional teaching appliance.Next,case study of visualization teaching in junior middle school physics experiment is carried out.This paper analyzes the problems in the teaching process of experimental visualization,summarizes the principles of experimental visualization,puts forward four experimental visualization strategies,and presents three visualization cases.Then carry on the practice research of physics experiment visualization teaching in junior middle school.In grade eight,two parallel classes conducted a comparative experiment between experimental visualing teaching and traditional physics experimental teaching.Combined with pre-and post-test analysis,questionnaire survey results,classroom observation and individualinterviews,the following conclusions are drawn:Physical experiment visualization teaching can promote cognition,stimulate learning interest and improve experimental operation skills.
