A Study Of Olympiad Test Questions Based On Evaluation Of Students' Chemistry Ability

In today's world,science and technology are advancing rapidly and the competition for highly qualified personnel is becoming more and more fierce.Capacity as an important indicator of evaluation of talent has aroused widespread concern in the community.At the same time,basic education in our country shows a trend of coexistence of popular education and excellent education,and coordinated development.Among them,the discipline competition is an important way of excellent education.Chinese Chemical Olympiad as an important high school student extracurricular competition,it is of great significance to select and cultivate students with comprehensive ability and scientific literacy to help them to grow into leading cadres in the chemical education and research fields as soon as possible.In recent years,the study of chemistry competition test questions has drawn high attention from high school chemistry teachers,competition training workers and university researchers.Among them,the research on special topic studies and the whole set of test questions is the most common,and there are few systematic studies on the test questions.Therefore,based on the recent 20 years' Chinese Chemistry Olympiad(preliminary competition),the paper summarizes the core examination points of the national senior high school students' Olympic competition preliminaries from the macro and meso two aspects through literature research and text analysis.To sum up the trend of test questions and test questions,this paper discusses how to gradually change from knowledge to ability.The following conclusions can be drawn from the study: the Chinese Chemistry Olympiad(preliminary competition)examination tends to diversify the students' chemistry ability,and the test questions tend to rely on specific knowledge test sites to evaluate students' ability in chemistry,the diversification of the sources of examination materials and the change of examination questions from knowledge orientation to ability conception.Finally,in the micro aspect,we select representative topics,analyze the problem solving methods in detail,analyze the development trend of competency oriented chemistry contest examination in real time,and elaborate the development trend of chemistrycompetition for the comprehensive cultivation of chemical core literacy of middle school students.And competition training and test research put forward the corresponding suggestion,it hopes to provide some reference value for the future training of chemical teachers and promote the professional development of young teachers and healthy development of chemical competition.
