The Current Situation Of Chemical Experiment Teaching In Senior High School And Its Analysis And Countermeasures

Chemistry is a natural subject which is based on the observation and study of experimental phenomena.Its research content is: at the atomic and molecular level of the composition,structure,physical and chemical properties,synthesis methods and applications of the basic science.Because its research content needs to be verified by experimental methods,so the experiment is the basis and soul of chemistry.Chemical experiment teaching is an important part of the ordinary high school chemistry teaching,the quality of experimental teaching is the teaching quality of high school chemistry education,because through the chemical experiment teaching can effectively stimulate students interest in chemistry course,can improve the students’ ability of questioning,observing ability,exploring ability and ability,also can help students improve analysis and problem solving ability.But in the actual teaching process,chemical experiment teaching can not play its unique role.The main reason is the limitation of high school teaching conditions;Secondly,teachers have not been completely removed from the influence of traditional teaching methods.Although with the implementation of the new curriculum standard of chemistry,some teachers have begun to pay attention to the importance of chemical experiments,but the degree of attention is not enough.Due to the limitation of various conditions and the influence of traditional teaching,the neglect of chemical experiment teaching leads to the failure of chemical experiment teaching to play its unique role.At present,although the implementation of the new curriculum standard of chemistry and the cultivation of students’ scientific inquiry literacy is the key period,there are still many problems in the actual chemistry experiment teaching of senior high school due to the economic imbalance and teachers’ insufficient awareness of experimental teaching.This paper first through consulting information,the current situation of the domestic and foreign chemical experiment teaching data survey,through comparison found that China’s chemical experiment teaching and foreign high school chemical experiment teaching there are certain differences.And part of high school in tgo area as the research object,through questionnaire investigation and interview method chemistry experimental objective conditions for schools,teachers,the chemical experiment teaching present situation investigation,understand the student,the chemistry teacher and teacher understanding of the chemical experiment laboratory,attitude towards experiment teaching,experiment teaching evaluation system,etc.Under the guidance of the new teaching theory,the data obtained from the investigation are analyzed and sorted out,and the approaches to solve the problems are studied.The following strategies are obtained: First,to improve the political position of chemistry teachers and to fully implement the new curriculum standards in chemistry teaching.The second is to improve teachers’ teaching quality and teaching level,change the traditional teaching mode,and promote students’ enthusiasm for experimental learning.Thirdly,we should pay attention to the process management of students’ experiment,optimize the evaluation method of experiment teaching,and encourage students’ interest and enthusiasm in experiment.Fourthly,create necessary conditions for experimental teaching,optimize experimental content,and promote students’ innovation and creativity.The research results of this paper are expected to provide reference for the implementation of Tongliao’s 2017 edition and 2020 revision of chemistry curriculum standards for senior high schools.
