Research On The Training Of Senior High School Physical Modeling Ability Based On Original Physical Problems

The construction of physical model plays an important role in physics teaching and is an important part of core literacy.Physical model is constructed by abstracting actual phenomena,and then physical phenomena are recognized by physical model.It not only helps the development of students' scientific thinking,but also links social life and physical knowledge more deeply,satisfying the curriculum concept of "from life to physics,from physics to society" in the curriculum standard.The original physical problem is the description of the actual physical phenomenon.Compared with the exercises,the original physical problem has the characteristics of openness,exploration and interest.It takes experience to describe phenomena and build models to solve problems.This paper through the analysis of students to solve the original physical problems of the status quo,and then teaching practice analysis of teaching effect,finally summed up the teaching strategy.The first chapter expounds the important role of original physics problem and physical modeling in high school physics teaching from the aspects of the requirements of the new curriculum standard and the national requirements of high school education.Analyze the relevant literature and expound the research status of this subject at home and abroad.Therefore,the purpose and significance of this study are clarified.The second chapter refers to the literature,defines the concepts of the original physical problems and physical models,and analyzes the modeling ability of students based on the original physical problems from the theoretical basis of constructivism theory,humanistic theory,problem teaching theory and Marxist philosophy principle,so as to provide theoretical support.Chapter three studies the current situation of high school students' solving primitive physical problems.First of all,through the pre-test,we understand the problems existing in solving the original physical problems and constructing the physical model.Through interviews,students communicate with students to further understand their views on the original physical problems and their mastery of physical models.The fourth chapter,according to the conclusion of the preliminary investigation,selects two senior one classes with similar average score of physics in the mid-term examination of the author's school,and sets up the experimental class and the control class.Combined with the guidance of teachers in practice schools,the teaching design and teaching practice based on original physics problems were carried out for experimental classes.At the end of the practice,the model test was carried out for the two classes,and the test results were analyzed,and the midterm and final exam scores of the two classes were compared.It was concluded that the original physics problems were of certain help to students' modeling ability and exam scores.According to the previous practice,summarize the teaching strategy.The fifth chapter summarizes the content of this research,and makes it clear that introducing original physics problems can promote students' modeling ability and improve their physical learning performance.
