Research In Theoretical Questions Of The Semi-final Contest Of Chinese Physics Olympiad Based On SOLO Taxonomy

Chinese physics competition for middle school students has been held for 36 years since 1984.The competition has become an important way to select and train excellent high school students.Every year,a large number of outstanding students open their doors to top universities through the physics competition.As the examination questions of physics competition have high requirements on students' thinking ability,it is an important issue worthy of attention and research to study the examination questions of physics competition and analyze their requirements on students' thinking ability.This thesis applies SOLO Taxonomy to divide thinking ability of examination questions into four levels:single-point structure level,multi-point structure level,associated structure level and extended abstraction level.Select the theoretical questions in semi-final physics contest from the 26th to 35th as research objects,which is carried on the thinking ability level division.Then make statistical analysis for each session examination of thinking ability level.and each knowledge part of examination of thinking ability level.In addition,the classical cases of mechanical,electromagnetism,thermal,optic,modern physics.The analysis shows that the theoretical questions in semi-final Chinese Physics Olympiad has the following main characteristics:1.The type and quantity of examination questions in the semi-final contest from the 26th to the 35th are basically the same.Most of them are calculation questions,the number of questions in each year is 8-9.Among them,the mechanical part has the highest proportion,followed by electromagnetism,the proportion of thermal,optics and modern physics is basically the same at 10%.2.According to the results of SOLO classification,the proportion of each level of thinking ability in the 26th-35th questions of the semi-final examination is highly consistent.The problem of extended abstract structure(E level)is the most examined,the problem of associated structure(R level)is the second,the problem of single point structure(U level)and the problem of multi-point structure(M level)is the least examined.As a whole,the paper requires very high thinking ability.Combined with the analysis of each knowledge part,the five parts are mainly focused on the problem of extended abstraction structure level,followed by the problem of the level of associated structure.The overall level of thinking ability of the five knowledge parts is ranked from high to low,which is electromagnetism,mechanics,thermology,modern physics,and optics.3.The analysis of four kinds of thinking level problems shows that the thinking characteristics of single-point structure level and multi-point structure level problems are mainly to examine the basic physical concepts,physical properties and physical laws.The thinking characteristics of associated structure level problems are reflected in two different logical associated types of knowledge points:"parallel type" associated problem and "series type" associated problem.The thinking characteristics of extended abstract problems are mainly reflected in the application of four thinking methods,which are physical thinking method,physical characteristic problem-solving method,logical reasoning,and mathematical tools.Based on the above research results.some suggestions is put forward on the teaching of the physics competition coach and the study of the physics competition students,so as to make the competition coach and the students have a deeper understanding and grasp of the thinking ability of the examination questions in the second round,which is helpful for the competition coach to guide and train the students better,so that the contestants can achieve excellent results in the physics competition.
