Advanced Study On The "Circuit And Its Application" Part Of Middle School Physics

The “circuit and its application” part of middle school physics runs through the learning of junior high school and high school,which is the key content of middle school physics.The content and rules of this part are complicated and complicated,so that students' learning knowledge is scattered and difficult to form a system,which is the difficult content of middle school physics.In order to strengthen the systematic teaching of the “circuit and its application” part of middle school physics,this study uses the method of empirical research to conduct advanced study of the “circuit and its application” part according to the development process of advanced learning.The advanced learning takes subject core concepts as research objects,which can change students' scattered knowledge and lack of systematic problems,help students master the core concepts of “circuits and their applications” step by step,integrate subject structure,and help teachers strengthen systematic subject teaching.The main purpose of the research is to determine the core concepts and important concepts of the “Circuits and Applications” section,and to build the advanced learning framework of the “Circuits and Applications” section,with a view to providing reference for practical teaching.According to this,the paper mainly contains the following contents.In the first part,by analyzing the requirements and textbook content of the “circuits and their applications” in the junior and senior high school physics curriculum standard,it is determined that the core concepts of the “circuits and their applications” are “the laws of DC circuits” and “the rules of circuits 'Energy”,combined with the subject logic and the opinions of middle school teachers,to build the advanced learning hypothesis of the“circuit and its application” section.The second part is to verify and modify the advanced learning hypotheses in the“Circuits and Applications” section.First,prepare the junior and senior high school test questions in the "Circuits and Applications" section to test the students for the first time;second,select the Rasch model to analyze the results of the first test,and then modify the test questions based on the analysis results to perform the second test.Obtain the test questions that meet the standards,such as reliability and fit.Finally,the junior high school test questions are equalized.The test results are used to verify and modify the advanced learning hypotheses in the “Circuits and Applications” section to obtain research conclusions.In the third part,according to the advanced learning framework of the "circuit and its application" part,the teaching design of the subject of the three compulsory "Ohm's law of closed circuits" in high school physics is tested,and the research conclusion is tested in the classroom.
