Research On The Experimental Setup Of The Chapter Constant Current In High School Physics Textbook Of China In The Past 70 Years

The physics textbook is compiled according to the physics teaching syllabus or curriculum standard.It is an important carrier to teach physics knowledge,train physics thinking,learn scientific methods and carry out ideological and moral education.At the same time,it is also one of the most basic and important physics curriculum resources in middle school.Experiment is the basis of physics and experiment is an indispensable part of physics teaching.However,in the process of practice,it is found that there is a phenomenon of formality in physics experiment teaching in Liaocheng City.In addition,the knowledge of electricity is an important part of physics.Since Edison invented the electric lamp,electricity has really become a resource that ordinary people can enjoy.Therefore,human beings have entered the era of electricity,and the application of electricity in life and production has become more and more extensive.Based on the above three points,the author decided to carry out the research on the electrical experiment of high school physics textbook.When combing the relevant literature,the author found that many researchers focus on the research of the old textbooks in recent years.They hope to enrich the relevant research fields through researching and analyzing the old textbooks.At the same time,it can also provide a certain reference for today's education and teaching.Therefore,the author plan to study the experimental part of the chapter "constant current" in 12 sets of high school physics textbooks of the past 70 years since the founding of the People's Republic of China,so as to provide some help for the experimental teaching and textbook compilation in the future.This study is divided into the following two parts:In the first part of this study,12 sets of textbooks are selected as the research objects,which are divided into seven stages: transition stage,comprehensive study of the Soviet Union,exploration and development stage,ten-year turmoil stage,rectifying the chaos,compulsory elective stage,new curriculum reform stage(three-dimensional goal stage,core literacy stage).The situation,structure of textbooks,the number of experiments,types of experiments,contents of experiments,presentation of experiments,ways and methods of experiments are statistically analyzed.It can be found that: 1.The embodiment of humanism in Chinese textbooks is gradually strengthened,and different versions of textbooks are compiled according to different needs.2.The contents are more systematic and abundant,the introduction part is more diversified,and the subject text,subject pictures,celebrity Quotes and directories are added.3.The types of experiments have not changed much,and exploratory experiments and applied experiments have always taken the leading position;the frequency of the experiment in the teaching material is greatly increased,and the proportion of various types of experiments is little changed.4.The experimental presentation mode is more and more diversified,with demonstration experiments that play the role of introduction and demonstration,students' component experiments that exercise students' practical ability and creative thinking,and extracurricular small experiments that play the role of consolidation and expansion,which are distributed in various small columns.5.Experimental instruments have not changed much.They are basic electrical experimental instruments;Experimental illustrations are more and more diversified.The experimental schematic diagram,the experimental operation diagram,the experimental device diagram and the experimental data processing diagram are gradually added;The common characteristics of Chinese physics textbooks are that there are many declarative sentences,imperative sentences,strong dominance,which is not conducive to the development of students' subjectivity.6.The experimental methods are more and more abundant.In the second part of this study,we use the questionnaire survey to collect and analyze the information collected.We can find that: 1.No matter from the perspective of teachers or students,the vast majority of teachers and students can realize the importance of experiments,and most of students can have a keen interest in experiments.2.Teaching methods and means are not advanced enough,but remain in the shadow of exam oriented education.3.The experiment in the experiment teaching is not closely connected with the actual life,and the extracurricular experiment activities are seriously lacking.4.The laboratory is the lack of laboratory resources and openness.5.The evaluation method of experiment is not scientific,and it mostly exists in the way of exercises.Through the above two aspects of research,I hope to provide some reference for the curriculum reform and the teaching of physics experiment.
