The Applied Research Of Primitive Physics Problems In Physics Teaching In Junior Middle School

The physics curriculum for compulsory education aims at improving students' scientific literacy.The teaching of original physics problems is helpful to promote the three-dimensional objects of students to be achieved harmoniously,and it is of great significance to improve the scientific literacy of students.The theoretical supports involve the Educational Ecology Theory,the Dual Constructivism Theory,the Dewey's Experience Organization Principle and the Concept of New Curriculum Standard,and the research methods include literature research,empirical research and action research in this thesis.The thesis discusses the application of primitive physics problems in junior high school physics teaching,taking the investigation and research of regional schools as objects.Firstly,on the basis of in-depth study of relevant literatures and educational theories at home and abroad,the necessity and feasibility of original physics problems teaching in the application of physics teaching in junior high school are analyzed in this thesis.Next,the thesis studies the application of primitive physics problems in junior high school physics teaching by conducting a series of surveys,tests and interviews over the following perspectives students' situation of learning physics,students' cognition of original physics problems,students' ability to deal with original physics problems and teachers' cognition of original physics problems teaching,etc.The results show that the cognition of original physics problems and the ability to deal with original physics problems of students are greatly related to teachers' teaching methods and their current learning situation.Then,the application principles(that is,authenticity,scientificity,subjectivity,objective,teaching students accordance with their aptitude,incentive and openness)and strategies(that is,choosing appropriate physical problems,applying primitive physics problems from multiple links,carrying out extracurricular practice activities,and infiltrating experimental teaching)of primitive physics problems in junior high school physics teaching are discussed.Finally,based on the textbooks and students,combined with the principles and strategies,the thesis analyzes the ways of collecting and compiling the original physics problems,and designs the original physical problems in seven chapters and two excellent teaching cases to carry out teaching practice and empirical research.Through the feedback of ability test of solving primitive physical problems and oral record of physical learning situation from the students,the effects of the primitive physics problems teaching are compared and analyzed,and the conclusions of this thesis are as follows: The strategies of original physics problems in junior high school physics teaching have strong maneuverability.The primitive physics problems promotes the teaching and learning of teachers and students.The innovations of this thesis lies in:(1)Nearly 60 primary physical problems have been collected and compiled from the chapters of physics textbook in the educational editions of the junior high school;(2)Two teaching cases are designed and developed for the application of primitive physics problems to the practice of physics teaching in junior high school;(3)Two ways are used to test the effect of primitive physics problems apply to teaching practice.
