Analysis Of Chemistry Experiment Questions In College Entrance Examination And Research On Review Strategies

The college entrance examination,which is called the unified national examination for enrollment of ordinary colleges and universities,has high reliability,validity,discrimination and a certain degree of difficulty,which reflects its social value in cultivating h igh-quality talents for our country.Experiments are the foundation of chemistry.The chemistry experiment questions of the college entrance examination test the achievement of students' chemistry core literacy from the perspective of evaluation,and reflect the teaching situation of the chemistry experiment part of the frontline chemistry teachers.Based on the "General High School C hemistry C urriculum Standards(2017 Revised in2020)" and "C hina College Entrance Examination Evaluation System",this article has studied a large number of relevant documents,and has studied multiple intelligence theory,constructivism theory,"learning by doing" theory and Bloom O n the basis of the classification theory of educational goals,the paper analyzes the chemistry experiment questions of the National Science Comprehensive ? College Entrance Examination in the past five years as a whole,and conducts investigations on senior high school chemistry teachers and senior middle school students who choose chemistry subjects.Comprehensively use literature research method,text research method,questionnaire survey met hod and test method to make statistics on the types,value weights,test contents,test situation,presentation methods and specific test sites of the 2016-2020 National Science Comprehensive ? College Entrance Examination Test Q uestions Analyze;design teacher questionnaires from six dimensions to understand high school chemistry teachers' understanding of college entrance examination chemistry experiment questions and their understanding of students' problem-solving skills;compile student test papers to understand the answers to senior middle school students' college entrance chemistry experiment questions,and analyze data To study the points lost by senior high school students in answering chemistry experiment questions.The data is processed with the help of statistical software SPSS26.0 and Excel spreadsheet.On this basis,the review strategy for the chemistry experiment questions of the college entrance examination is proposed: firstly,we must consolidate the foundation,clarify the chemistry experiment method,pay attention to the relevant requirements of the chemical experiment knowledge and ability in the curriculum standard;secondly,return to the textbook and integrate the "experiment" set in the textbook.In the XX" column,the experimental content involved should be used as the key review content to clarify the experimental purpose,experimental methods,experimental principles,experimental precautions and other necessary chemical experimental knowledge and key capabilities of chemical experimental investigation for each experiment.At the same time,it is necessary to be good at using materials such as life and production practices,scientific frontier achievements and other materials to create real situations to help students improve their way of thinking in solving problems.Finally,it is necessary to summarize the methods,sort out the characteristics of the question types of the college entrance examination chemistry experiment questions,and propose corresponding problem-solving methods according to different question types.Train students' problem-solving thinking and improve their problem-solving ability.All in all,the college entrance examination chemistry experiment test questions are designed to test the comprehensive ability of students' experimental exploration,based on the basic chemistry experiment knowledge and skills,to comprehensively evaluate the students' chemistry core literacy.The research aims to provide help for chemistry teachers and senior three students who review the chemistry experiment questions of the college entrance examination.
