Research On The Exploration And Transformation Strategy Of The Former Concept In Middle School Physics Teaching

Traditional teaching methods tend to treat students as a piece of white paper,the scientific concept of hard to lay on the white paper,ignoring the existence of the minds of the students in all kinds of concepts,leading to the concept of students and scientific concepts confused or contradictory,The student's learning effect is relatively poor.In order to improve the learning effect of students,educators must pay attention to the students in the mind of the original existence of these per-concept,targeted to change the concept of teaching,in order to achieve good teaching results.Around this issue,the main contents of this paper are as follows:1.The use of literature and interviews to collect the secondary school students in the physical learning of the former concept,sorting out the relevant concept of the transformation of the literature,and then review the status of the former concept.2.In order to study the physical inertia,buoyancy and friction of the eighth grade of three schools in Panjin City,Liaoning Province,Changsha City,Hunan Province and Ordos City,Inner Mongolia Autonomous Region as the research object,the second-order diagnostic questionnaire was designed.Explore the preconceptions in the minds of the students and analyze the test results of the questionnaires.3.According to the test results of the per-measured questionnaire,combined with the design concept in the process of changing the strategy,for the existence of the former concept of the need for targeted design,to take a specific teaching resources for teaching,this study has taken micro-video,homemade teaching aids,Design experiments,etc.to develop teaching resources,and then the overall classroom design and fine classroom teaching design.4.In the process of teaching practice test,select the experimental class and the control class respectively teaching,the experimental class according to the results of the former concept of exploration of the corresponding concept of the concept of change strategies and the implementation of teaching in the control class in accordance with the traditional teaching methods of teaching.After the end of the classroom teaching,respectively,the experimental class and the control class students in a timely manner after the test,through the results of the two classes of students before the concept of change.After a period of time and then the experimental class and the control class students to conduct a delay after the test,analysis of the conceptof the former students change.The main conclusions of the study are:1.through the study of the object before the concept of exploration,the exploration of inertia ? buoyancy and friction Points in the existence of a large number of per-concept,and the problems in the pre-test conducted a fine analysis.2.In the analysis of the questionnaire before the concept of the process,we can see in the inertia,?buoyancy and friction of the three aspects of the former concept of the impact of life experience,the lack of conditions?forgotten and brought by the words and other factors.3.In the three previous concepts of the transformation strategy,teachers have adopted the production of micro-video,design experiments,production teaching aids,such as the implementation of the concept of change teaching.In the future of the former concept of change in teaching,this method also has a significant reference.
