Investigation And Practical Research On The Current Situation Of High School Chemistry Experiment Teaching In Qiannan Prefecture

Chemical experiments help to stimulate students' interest in learning chemistry,help students understand and master chemical knowledge and skills,enlighten students' scientific thinking,cultivate students' scientific methods,cultivate students' scientific attitude and values,and then achieve the role of cultivating students' scientific literacy.Senior high school chemistry experiment is an important part of senior high school chemistry curriculum and an important content of basic education chemistry curriculum reform.However,under the influence of exam oriented education,the senior high school chemistry experiment teaching in many areas of our country has been in a weak position for a long time,especially in the underdeveloped areas.Qiannan Buyei and Miao Autonomous Prefecture(hereinafter referred to as Qiannan prefecture)is an underdeveloped minority area in Guizhou Province.the conditions of running high schools in area are mostly difficult,the teaching facilities are relatively backward,and the teachers are re latively weak.How to carry out the chemistry experiment teaching of high school chemistry teac hers in this area? What are the problems in chemistry experiment teaching? What are the factors?To study these questions,it is of positive practical significance to help high school chemistry tea chers in underdeveloped areas to improve their understanding of experimental teaching,to prom ote the development of experimental teaching,to improve students' nuclear b literacy by learning enthusiasm E and to improve students' nuclear b literacyThis study takes chemistry department teachers and students of Qiannan middle school as the research object.This paper mainly uses the methods of literature,questionnaire and teaching experiment to investigate the current situation of chemical experiment teaching in Qiannan middle school.It is found that there are some main problems in the chemical experiment teaching in Qiannan middle school.(1)On the school side: the school does not pay enough attention to the laboratory construction,the arrangement of chemistry curriculum is unreasonable,the specific requirements for teachers to carry out students' experiments are not in place,and the investment of chemistry experiment teaching resources is insufficient;(2)Teachers: lack of correct understanding of chemical experiment teaching,lack of initiative in experiment teaching,low requirements for their own development,insufficient attention to students' experiment,single evaluation method of students' experiment,and no attention to extracurricular experimental activities teaching;(3)Students: most of the students lack of correct understanding of chemical experiments,their attitude towards chemical experiments is not serious enough,they do not form good experimental habits and methods,and their chemical experiment skills are poor.Based on the analysis of the existing problems and related factors in the chemical experiment teaching of Qiannan Prefecture senior high school,this paper studied the practice of the chemical experiment teaching of senior high school by strengthening the chemical experiment teaching.The results showed that the chemical experiment teaching improves the students' chemical achievements,promotes the cultivation of the students' scientific core literacy,and improves the students' interest in learning chemistry.In view of the problems existing in the teaching of chemical experiment,combined with the practical research of experimental teaching,this paper puts forward some suggestions for the teaching of chemical experiment in Qiannan middle school: increasing the investment in chemical experiment,ensuring the basic resources of chemical experiment teaching;changing the educational concept of teachers,strengthening the teaching of chemical experiment;developing the teaching of chemical experiment,enriching the teaching mode of chemical experiment;strengthening the teaching of experiment management,improve the evaluation mechanism;strengthen the construction of teachers,and promote the professional development of teachers.
