Analysis Of Chemistry Experiment Questions And Research On Teaching Strategies In Jiangxi Senior High School Entrance Examination

Chemistry is an important subject in middle school in our country,and experiment is the base of chemistry.Therefore,the chemical experiment questions play an important role in the chemistry.The ability of students' chemistry is mainly embodied in the ability of chemical experiment,So it becomes important for students to master the chemical experiment in the senior high school entrance examination.This paper mainly adopts the methods of literature research,questionnaire survey and case analysis.Based on the analysis of the chemistry experiment questions in Jiangxi senior high school entrance examination from 2016 to 2018,the characteristics of the chemistry experiment questions in Jiangxi senior high school entrance examination from 2016 to 2018 are summarized.It is hoped that teachers can understand the characteristics of the chemistry experiment questions and have a comprehensive understanding and mastery of the chemistry experiment questions in the senior high school entrance examination.Some teaching strategies are put forward,which are expected to play a positive role in promoting junior high school chemistry experiment teaching,improving experiment teaching and reviewing the entrance examination.The first chapter mainly introduces the background of the research,the current research situation of related topics,innovation and characteristics of research,the theoretical basis,methods of the research.In the second chapter,some statistics and analysis are made on the structure,scores and test points of the chemistry test of Jiangxi senior high School Entrance Examination from 2016 to 2018,from which the characteristics of the chemistry experiment questions are summarized:(1)checking the basic experimental knowledge;(2)checking the students' ability of applying the basic knowledge;(3)checking the students' ability of scientific exploration.In the third chapter,the current situation of junior high school chemistry experiment teaching in Jiangxi is investigated by questionnaire,then made statistics and analysis on the results of the survey.The results show that most teachers know the importance of the experiment.Because of the limitations of various practical factors,it is very difficult to carry it out.Based on the analysis of the characteristics of the chemistry experiment questions in the senior high school entrance examination from 2016 to 2018 in Jiangxi Province and the current situation of the experiment teaching,and the investigation and analysis of the students' attitudes and perceptions towards the chemistry experiment,this paper puts forward some strategies for junior high school chemistry experiment teaching,including:(1)carrying out the requirements of curriculum standards,let students familiarize with the basic knowledge of chemical experiment;(2)focusing on the process of experimental exploration,cultivating the students' ability of scientific exploration;(3)focusing on the experimental teaching in the review stage.In the fourth chapter,carries out the teaching practice of the proposed teaching strategies.A comparative analysis of the results of the implementation of teaching strategies was made,and a questionnaire survey was conducted among the students in the experimental class.The results show that the flexible use of these teaching strategies has a significant effect on improving students' chemistry scores.The students' interest and initiative in learning,and the ability to design experimental programs have also been improved.In the fifth chapter,summary and prospect,elaborates the conclusions and prospects of the research.
