Research On The Teaching Mode And Method Of Chemical Experiment In Middle School

Experimental teaching is an important part of chemistry teaching,which is also an important way to cultivate students' core accomplishment in chemistry.The primary task of chemistry teaching is to develop experiment teaching actively.However,in the current middle school teaching process,the experiment teaching method is single,the teacher does not pay attention to carry out the chemistry experiment teaching.In order to change the single experimental mode and guide teachers and students to attach importance to experimental teaching,a variety of experimental teaching methods are proposed.Through the transformation of experimental teaching methods,students' participation in experimental teaching is improved,which provides students with the opportunity to carry out chemical experiment inquiry training and effectively improves students' core quality of chemistry.Firstly,this paper summarizes the research background and significance and the current situation of experimental teaching at home and abroad by consulting a large number of literatures.Based on the analysis of the new curriculum standard,examination outline and examination paper,the important position of experiment teaching in chemistry teaching is concluded.Secondly,in order to improve the effectiveness of experimental teaching,the "preparation and properties of SO2"experiment was improved by miniaturization,and students were allowed to operate the experiment."Comparison of the properties of Na2CO3 and NaHCO3" is made into an experimental micro-class and integrated into classroom teaching.Virtual simulation experiment software is used to assist the experiment teaching,and"chlorine and its compounds" are selected as a case of diversified experimental teaching means.The first grade of M middle school in Tongliao city is studied as the research object.Three cases are designed and practiced for teaching,and the teaching effect is analyzed by means of question and answer,individual interview and questionnaire survey.The results show that the above experimental teaching methods can improve the effectiveness of experimental teaching.Finally,the conclusion is drawn that the miniaturization experiment teaching is conducive the improvement of students' comprehensive quality,the experiment micro class is helpful to the transformation of teaching mode,and the virtual simulation experiment software is helpful to the transformation of students' learning style.
