National 12 Provinces And Cities High School Chemistry Competitionpreliminary Examination Questions Comparative Study

There have been a lot of valuable research results on the test questions of high school chemistry competition in China,but these studies are basically based on the national preliminary and final questions,and less attention is paid to the most extensive preliminary stage of high school chemistry competition in China.At the same time,the previous studies mainly focused on the solution method of the test questions and the training mode of the contestants.The perspectives and entry points of the research were one-sided and superficial,and the systematic research on the test questions of the chemistry competition was rarely conducted from the perspective of the knowledge and ability of the chemistry discipline.Therefore,this study is mainly carried out from two aspects of subject knowledge and subject ability.At the same time,the structure of test questions,requirements of preliminary examination and outline of preliminary examination of chemical competitions in various regions are compared,forming a relatively systematic study.This study mainly adopts literature analysis,mathematical statistics,questionnaire survey and other research methods.First of all,based on the existing research results,a research framework for the preliminary test questions of the chemical competition is constructed.Secondly,the preliminary requirements of high school chemistry competitions in various regions are studied,and the preliminary outline of Zhejiang province and Guangdong and Guangxi provinces are compared.Thirdly,the preliminary examination questions in different regions are analyzed from two dimensions of subject knowledge and subject ability.The research scope includes the preliminary examination questions in 12 provinces,cities and autonomous regions of China in 2018,and the preliminary examination questions in Beijing,Zhejiang and Sichuan in 2014-2018.Meanwhile,the structure of the preliminary examination questions in different regions is compared.In the end,a questionnaire survey was conducted among the students of some middle schools in Sichuan province.This paper is divided into six parts:The first part is the research background,research purpose,research significance and literature review,mainly through literature review of existing research,in order to form the theoretical basis of this study.The second part is a comparison of the purpose and the scope of the topic of the chemical competition in various regions,and a comparative analysis of the preliminary outline of Zhejiang province and Guangdong province.The third part compares the structure of the test questions in the preliminary examination in 12 provinces,cities and autonomous regions,including the question size,the proportion of the question type,the way the questions are presented and the situation of the questions.The fourth part studies the preliminary examination questions of 12 provinces and cities in 2018 and the preliminary examination questions of Beijing,Zhejiang and Sichuan provinces in 2014-2018 from the perspective of subject knowledge and subject ability using mathematical statistics method.The fifth part is a questionnaire survey of the students participating in the preliminary contest of the chemical contest in Sichuan province,including the basic information of the students participating in the contest,their views on the chemical contest activities,participation motivation,access to relevant information and other channels.The sixth part is the conclusion and reflection.The research results of this study are summarized for further consideration.
