Research And Development Of Life-based Chemical Teaching Experiment In Middle School

Chemistry is a subject,which is closely associated with production and daily life,while "life-based" chemical teaching experiment in middle school is the feature and direction of teaching reform under the background of new curriculum standard.Focusing on the existing problems and plights in chemical teaching experiment,it both theoretically and practically explains the reasons why it is necessary to carry out "life-based" chemical teaching experiment as well as how to carry out it,with "life-based chemical teaching experiment in middle school" as the object of the research in this paper.The main content of this research includes:knowing about the current situation of life-based chemical teaching experiment implementation in middle school by means of questionnaire survey,based on the research status of this topic at home and abroad as well as the related theories,and then setting forth the necessity of life-based chemical teaching experiment implementation in middle school.On the basis of the study about chemical experiment in middle school,it provides the specific definition of "life-based chemical teaching experiment" and mentions that the development and research of "life-based chemical teaching experiment" shall conform to the principles of scientificity,operability,life-based,interestingness and safety,it also introduces several measures which could be adopted for the development and research of "life-based chemical teaching experiment",including life-based experimental apparatus and supplies,life-based experimental design scheme as well as life-based application of experimental principle.Based on the above-mentioned principles for the development and research of chemical teaching experiment,it describes four development cases obtained by using different development strategies,and each case is expounded,analyzed and evaluated in details.The study concludes that life-based chemical teaching experiment accords with educational theory and teaching rules,it is very necessary to improve or develop life-based chemical teaching experiment in the actual process of teaching,its advantage lies in the fact that it can arouse students' interest and motivation in learning,make teaching experiment more operable,and therefore it is an effective way to make up for the limitations in textbook compilation to some extent.
