Research In Preliminary Contest Of Chinese Physics Olympiad Based On Physical And Mathematical Core Literacy

With the advancement of the new round of curriculum reform,the core literacy of disciplines has become the key basis for evaluating students'academic quality.In recent years,physics entrance examinations for senior high school students have formed three levels:college entrance examination,physics competition and independent enrollment examination.Physics competition has gradually become a kind of specialty education which is highly concerned and favored by students,parents,schools and the society.Students participating in the competitions need to have rich physical knowledge,flexible scientific thinking,strong inquiry ability,rigorous scientific research spirit,and more importantly solid mathematical proficiency.In order to promote the teaching and preparation for physics contests,it is very important to study the test questions of Chinese Physics Olympiad based on the physical and mathematical core literacy.Taking the questions in the preliminaries of Chinese Physics Olympiad from 2014 to 2018 for research objects,with the methods of documentary research,comparative analysis and statistical analysis,based on the analysis of physical and mathematical core literacy and its constituent elements,this thesis will analyze the contest questions and physical and mathematical core literacy involved in the process of solving the problems from the perspectives of question types,score,knowledge plates,examination contents and problem-solving methods,and finally classify and count them to summarize the characteristics of the test questions.In addition,I will choose some,classical test cases,which are divided into five parts:mechanics,thermology,electromagnetics,optics and modern physics,to analyze and evaluate the level of core mathematic literacy of the test questions and their solution process so as to provide strategies for the test proposition.The results show that the questions in the preliminaries of Chinese Physics Olympiad have the following characteristics:1.College Entrance Examination is highly similar to physics contests in creating situations and examining contents;College Entrance Examination questions,especially the last computational ones,are often innovated or adapted from the questions in physics contests;the solving process of the last question in college entrance examination involves some commonly used solving methods in high school physics contests.2.In the past five years,the preliminary examination questions have been highly consistent in type,quantity and score.The full score of the test paper is 200,consisting of 5 multiple choice questions,5 filling-in questions and 6 calculating questions.Among all questions,the score of mechanics part accounts for about two-fifths of the total score,and it is the most important knowledge section to examine in the preliminaries.The score of the electromagnetics part accounts for about a quarter of the total score,so it is also a key part of the examination.By comparison,optics,thermology and modern physics do not account for much of the score.3.In the past five years,all the questions in the preliminaries have examined physical concepts,focusing on the ability of students to deal with problems by using the concepts of interaction and energy.Solving the problems requires students to master the way of scientific reasoning,use different reasoning methods to solve problems in different situations,and more importantly learn to explore unknown physical situations with known physical models.Students need to pay more attention to and think about physical phenomena and problems in life based on the understanding of classical physics experiments.The examination of the scientific attitude and sense of responsibility of students in the tests are presented in the form of scientific and technological current events,history of physics,social responsibility and scientific research spirit,among which scientific and technological current events are the most frequently presented.4.The examination of mathematical core literacy is reflected in the problem-solving process.The preliminaries have a strong demand for mathematical operation ability,and more importantly require students to have the ability to abstract mathematical relations from physical phenomena and the ability to combine numbers with shapes.Researching the questions in the preliminaries of Chinese Physics Olympiad can make more students and teachers have a deep understanding of the relevant contents of physics contests,the characteristics of preliminary questions,the rules of proposition and the examination of core competence,thus help the teaching and preparation for the competition,and bring the cultivation of Physical core literacy down to earth.
