Research On The Solution To Strengthen Junior Middle School Students'Real Sense Of Applied Physics Knowledge

It has always been the research hot spot of middle school physics which includes paying attention to students' cognitive characteristics,strengthening the connection between the course content and students' life and the relationship of developing modern society and scientific technology,letting students to experience the process of scientific inquiry,learning scientific research methods,and cultivating their innovative spirit and practical ability.It is also important subject of knowledge application research that how to apply physical concepts and laws to explain phenomenon and solve physical problems.In order to strengthen the junior high school students,who use physical concepts and laws to explain phenomena and analyze and solve problems.Enhancing the real sense of cognitive level,which help students to build their self-confidence in physical learning.Developing problem-solving solutions,which help students to experience scientific exploration.Meanwhile,Showing the route of problem-solving process in the real sense so that achieve the purpose of solving practical problems andstrengthening the application of physical knowledge.By using a method of literature review,this research makes a comprehensive studying on the content,significance,methods and approaches of the combination of reality and physics,as well as the current research situation of enhancing reality to realize knowledge application in the process of problem-solving,which finds the lack of research on problem-solving.Based on the necessity and feasibility of strengthening junior high school students' physical knowledge application in problem-solving process mode,and the necessity and feasibility of enhancing students' cognitive level through designing problem-solving cases,the concept of ‘real sense' and ‘problem-solving cases' are defined,the structure and design principles of problem-solving cases are defined,and the practical process of problem-solving cases is summarized.On the basis of a large number of problem materials related to real life,we choose the phenomenon with local characteristics of the internship area and the tool closely connected with students' real life as the task driving of problem-solving,and designing,compiling and practicing the problem-solving in combination with design principles.Using action research method,the author selects a middle school class in Hohhot for a semester of teaching practice research.The research analyzes and evaluates the problem-solving solutions from four perspectives: Students' problem-solving feedback,after class exercises,teachers' discussion andquestionnaire survey.The research results show that the design of the problem-solving solution suitable for the needs of junior high school students' physics learning,effectively combining physics teaching with real life,and enhancing the sense of reality in the process of problem-solving.It is conducive to infiltrating the thinking and methods of problem-solving into students,promoting students to form critical thinking,strengthening the application of physical knowledge,and promoting students' self-confidence and feeling the joy of success.
