Research On The Teaching Status Of Idealized Model Construction In High School Physics

The Physics Curriculum Standards for General Senior High School(2017 Edition)summarizes the core accomplishment of physics subject on the basis of three-dimensional objectives,among which model construction is an important way to develop scientific thinking.And the content of the course clearly points out the modeling activities of each module to establish the core concept.It can be seen that under the new curriculum reform,more and more attention has been paid to the teaching of model construction.However,under the influence of exam-oriented education,most teachers pay more attention to the construction of physical model in problem solving in the actual teaching,but ignore the requirements for the construction of physical model in the curriculum standard.Therefore,it is very necessary to observe the implementation status of high school physics model construction teaching from the details,at the same time,it is expected to provide guidance for teachers' model construction teaching through the investigation of the status quo.This study mainly adopts literature research,classroom observation and interview survey.First of all,read the literature,discuss the teaching theories related to the construction of idealized physics model,and formulate the class observation table.Secondly,from the teaching process of model construction and the implementation of the teaching process to observe the current situation of high school physics idealized model construction teaching teachers;Finally,part of the teachers in the practice school were interviewed to supplement the classroom observation,so as to comprehensively investigate the current situation of the construction of idealized model of high school physics teaching.Through the investigation,the following conclusions are drawn: First,teachers do not have a clear grasp of the concept and process of physical model,idealized physical model,model construction.Concretely,teachers appear in the teaching model construction process is not complete and the order of the model construction process is reversed.Second,teachers fail to let students really experience the process of model construction.Embodied in teachers did not provide the real situation,there is no clear core issue,in class without timely inspects the student to the idealized model and thinking method to study,and the task of modeling and material that is not clear,part of the model on the construction process of the lack of guidance,student teachers instead of explain,do not give students think time,etc.;Thirdly,teachers believe that model construction teaching can cultivate students'scientific thinking,and its teaching difficulties come from the immaturity of students'thinking and the complexity of physical model construction.
