Application Of Daily Necessities In Junior Middle School Chemistry Experiment Teaching

With the development of the times and the deepening of the new curriculum reform,curriculum reform is paying more and more attention to the important role of chemical experiment teaching in the exploration of chemical science.The content of experimental teaching in the new teaching edition of the new teaching edition is becoming more and more close to the daily life of the students,and more and more attention is paid to the ability to use chemical knowledge and chemical principles to explain some of the phenomena and problems in life.In the course of teaching practice,the author uses other supplies instead of the equipment and medicine for chemical experiment to carry out practical teaching experience,and puts forward the possibility of using daily necessities to carry out chemical experiment teaching.The purpose is to make the chemistry experiment teaching more effective and promote the development of students' individualization and the professional accomplishment of teachers.In the third chapter,a questionnaire is made to investigate the current situation of teachers' experiment teaching by using daily necessities.The results of the survey show that some teachers have the experience of experiment teaching with articles of life,and many teachers think that the use of daily necessities for experimental teaching can achieve good teaching effect.It takes a lot of time and energy to design and develop daily necessities as experimental contents,which is the teacher's use of daily necessities.The key problems in experimental teaching.The fourth chapter illustrates the application of daily necessities in chemical experiment teaching from the theoretical point of view.It gives a simple classification of daily necessities with chemical experiment teaching,analyzes its characteristics and educational value,and gives the corresponding application strategy,which provides theoretical support for the study of the fifth chapters.The fifth chapter is the content of experimental teaching case study.First,we analyze and screen the experimental teaching contents arranged in the current teaching materials,select the "inquiry of combustion conditions","fire extinguishing principles and methods" in the seventh units,and discuss the application and practice of daily necessities in the experimental teaching of chemistry.In the experiment 1 and the experiment 2,the students' study situation was examined in the form of unit specific test after teaching.The results showed that the teaching effect of chemicalexperiment on the use of daily necessities was proved to play an active role in the teaching effect.At the end of this paper,the results of the questionnaire survey and the effect of case teaching practice are used to reflect and discuss the problems and limitations of the safety and limitations of the articles in the chemical experiment teaching.The purpose of this paper is to better call for the researchers to solve the problems in the application of the daily necessities in the chemical experiment teaching and to better serve the chemistry teaching.
