Research On The Improvement Of Experimental Teaching Based On The Physical Experiment Operation Test In The Guangzhou Senior High School Entrance Examination

Physics is a natural subject based on experiment,and experiment teaching is an indispensable and important part of physics teaching,which plays an irreplaceable role in cultivating students' scientific literacy.Since 2000,various provinces and cities began to set up physical experiment operation examination,but because the result is not related to high school enrollment,the exam formalization problem appears.After noticing the problem,Guangzhou decided to start counting physics experiment operation scores into the total score of the entrance examination in 2021.In order to cooperate with the reform,schools in Guangzhou began to explore the improvement of teaching,hoping to find a teaching model that can subtly improve students' operational ability.According to the requirement of reform,this paper explores the improvement method of experiment teaching under the background that the results of physics experiment operation examination are included in the total score of high school entrance examination in Guangzhou.After studying the existing literature on experimental operation examination,by comparing the differences of experimental operation examination in Guangdong province,it is found that the results of experimental operation examination in each city of Guangdong province will gradually be related to the admission of high school entrance examination,and the importance of physics experimental operation teaching in each region is gradually increasing.There are differences in proposition among cities in Guangdong Province,which are caused by differences in test duration and proposition basis.There are differences in the scoring methods of various cities in Guangdong Province,and some areas have problems of formalization.There are differences in the scoring standards among cities in Guangdong Province.Guangzhou lays emphasis on the normative examination of experimental scheme,experimental procedure,instrument use method,data recording and processing,and operation.Guangzhou will be the experimental operation test results into the total score of the middle school entrance examination there are three main purposes: to promote teaching,to promote learning,to promote construction.Based on the requirements of the experimental operation examination in Guangzhou,a questionnaire survey was conducted among the students of a middle school in Nansha District of Guangzhou.It was found that the students were confused about the test content,process and scoring standard of the experimental operation examination.The interviewed junior high school teachers said that they would pay more attention to the cultivation of standardized experimental operation of students in the future experimental teaching.Based on the results of the survey,this paper compiled a set of meet the requirements of the guangzhou physics experiment operation exam questions and grading standards,and change traditional experiment grouping experiment link to simulation test operation,two students as a group,mutual test,introduce the compulsory education of physics curriculum standard(2011 edition)"20 experiment outside,Making experiment operation video micro lesson to assist the experiment teaching.The results show that the average scores of 81 students in three simulated experiments are 9.29,9.65 and 9.74,respectively.The average scores of the students in the experimental operation are gradually improving,while the average score of the traditional group experimental teaching method is only 8.68.In other words,the traditional grouped experiment link has some deficiencies in the normative training of students' experimental operation.The simulated experimental operation examination in the grouped experiment link of experimental teaching and the micro-class video of experimental operation can effectively improve students' awareness and ability of experimental operation standard.
