Research On The Application Of Micro-Class In Junior Middle School Physics Experiment Teaching

With the advent of the "Internet+" era,innovation,openness,and diversification have become the inevitable trend of future teaching.The state vigorously promotes the construction of educational information,which has laid a solid foundation for the integration of micro-classes and traditional teaching.In recent years,the Ministry of Education has hosted various micro-class competitions at all levels and promoted the application of micro-classes in subject teaching practice.This article focuses on the application of micro-classes in the teaching of junior high school physics experiments,and organizes the current research status of micro-classes at home and abroad through the literature research method,and provides a theoretical basis for the definition of the core concepts of this article;The questionnaire survey method is used to investigate the status quo of the junior high school physics experiment class and the views of teachers and students on the experimental micro-class.On this basis,a unified teaching design template for the experimental micro-class is designed,and the use strategy and flow chart of the experimental micro-class are formulated.One case of classroom teaching,one case of autonomous learning,and two cases of interesting experiment were selected from the ninth grade physics textbook published by the People’s Education Edition to teach the experimental class and the control class respectively;By comparing the evaluation test results of the experimental class and the control class,and analyzing the results of the experimental class students’ willingness of the experimental micro-classes,the application effect of the experimental micro-classes is evaluated,and the advantages of the experimental micro-classes in junior high school physics experiment teaching are summarized Reflected on the deficiencies in teaching practice.By comparing the results of the evaluation test of the experimental class and the control class,it is found that the score rate of the experimental class in the three types of evaluation test questions is higher than that of the control class,and it is more significant in the experimental questions.It can be seen that the application of experimental micro-classes has significantly improved the cultivation of middle school students’ experimental inquiry ability.After conducting a post-study questionnaire survey of experimental class students,the survey found that experimental class students have a higher acceptance of experimental micro-classes,and students expressed their interest in learning,concentration,and classroom participation.The use of experimental micro-classes is an effective supplement to the limited teaching time and equipment shortage.The experimental micro-classes are for students of different levels to learn independently,study repeatedly,and review independently,which to a certain extent realizes the effect of layered teaching.By recording the situation of students uploading experiment reports,it can be known that the application of experimental micro-classes to interest experiments can effectively enhance students’interest in learning physics experiments.Because students have a high acceptance of experimental micro-classes,they can try to apply experimental micro-classes to experimental teaching in other parallel classes.At the same time,you can try to apply micro-classes to other aspects of physics teaching(such as:training excellent and supplementary errors,systematic teaching of calculation questions,answering skills of multiple-choice questions,etc.),and can also be extended to the teaching practice of other subjects.In addition,the design and development of experimental micro-classes has far-reaching significance for the development of the multimedia application ability of the teacher group and the change of teaching concepts.
