Research On Current Situation,Problems And Countermeasures Of Chemical Experiment Teaching In Junior Middle School

Chemistry is based on experiments,experiment is an important teaching method in the teaching of various knowledge of chemistry.No matter looking back on the history of chemistry or the application of chemistry in current society,the influence of chemical experiment on the development of chemistry is irreplaceable.The new curriculum reform proposes to train students to learn new skills,knowledge and methods in experiments,and to cultivate students' ability of scientific inquiry,help students obtain information by means of investigation,observation,etc.The teaching of chemistry experiment in junior middle school emphasizes on cultivating students' ability of doing experiments and exploring,the transformation of the exam-oriented education to quality education,the reform focuses on improving students' quality and developing students' core quality.Take the guidance of ministry of education as the forerunner,the part of laboratory operation examination is added in junior middle school chemistry academic level examination,this is the embodiment of attaching importance to experimental teaching.However,in the practice of chemistry teaching,teachers and students often fail to understand the significance of chemical experiments,the basic ability of chemical experiment is low,learn chemistry experiments by rote,it restricts the development of students' scientific literacy.Based on this,the paper investigates the current situation,adopts the methods of questionnaire survey,observation and case analysis,the problems of junior middle school chemistry experiment in prefectural no.2 middle school in Quanzhou were studied,emphasis was placed on analyzing their attitudes to chemical experiments,cognition of experimental problems in chemistry,the problems existing in the teaching of chemical experiment were observed,analyzed and studied,then try to guide students from the establishment of a correct understanding of chemical experiments,construct the right way to study chemical experiment,the countermeasures to improve the teaching of chemical experiment are put forward.After analysis,found the problems existing in the current junior middle school chemical experiment teaching are as follows: the problems in current junior middle school chemical experiment teaching of laboratory opening degree is limited,lack of teachers' understanding of the chemical experiment subject value and experimental opening rate is low,low degree of opening laboratory,students' participation is not high,the old experimental teaching mode,teachers to motivate students is not enough,the experiment teaching of the single,multimedia can not be combined with conventional experiment,experiment teaching ability is weak,low efficiency of experiment teaching ability training.Policy advice is to increase the rate of opening laboratory,advocacy to encourage teachers guide students level,suggested that adjust the laboratory management system,strengthening equipment use,effectively implement encourage education mechanism,application of "four five main" teaching guide mode;Enhance the importance of chemistry experiment,integrate multimedia into experiment teaching,use experiment to improve teaching,enrich experiment cognition;Strengthen training students' experimental ability,improve teachers' research and innovation ability,guide students to carry out the experiment inquiry activity,improve the methods of experimental teaching,the selection of training outstanding experimenter,promote teachers' experimental operation innovation ability.The paper is divided into five parts.The first part is the introduction.This paper focuses on the background,significance,methods,contents and research status at home and abroad.The second part is the analysis of the present situation of chemical experiment of junior middle school students.Focus from an examination of the chemical experiment proposition standard operation,ability of junior middle school students in chemistry experiment in normal operation performance such as overall operation capability and performance aspects in this paper,the concrete operation ability,and the introduction of interview,questionnaire investigation,experimental observations survey,investigation,analysis and statistics of junior middle school students in our school at present problems in chemical experiments,influence factors and reasons.The third part is about the problems of middle school students in chemical experiment.The fourth part is the ability training strategy of middle school students in chemical experiment.The fifth part is summary and reflection.
