Study On The Design And Application Of The Physical Micro-Experiment Of Junior High School Life

Physics is an experiment based on science.In the classroom teaching of middle school physics,experiment is not only an important teaching content,but also an important teaching method.Therefore,the current subject teaching pays more attention to the teaching of experiment.Efficient classroom experiments will enhance students’ interest in learning,and help them to hunt and understand the physical knowledge in the experiment,and develop their cognitive abilities in the process of practice.In the physics teaching of middle school,the micro-experiment is simple,easy to operate and obvious phenomenon has entered the view of physics teaching workers.How to make use of the living things to make micro experimental apparatus,how to apply the physical micro-experiment of life to the classroom,it is worth to discuss.In the teaching of middle school physics class,the physical micro-experiment of life is playing an increasingly active role as a tool for assisting teaching.In physics class,teachers use the physics experiments of life to show the physical phenomena,students can understand the physical concepts and rules better by the observation of the phenomenon,effectively stimulate the desire for knowledge,and improve the interest in physics learning.Physics teachers can cultivate students’ observation ability,practical ability and innovation ability through physical micro-experiment,and cultivate students’ scientific emotion.This paper mainly studies the theory and application of the physical micro-experimental design of junior high school life.There are mainly six parts,the first part is the introduction,the research content and the research method are clear,and the present situation of micro experiments at home and abroad is elaborated.The second part is the theoretical foundation of this paper,which lays a theoretical foundation for the design and application of micro experiments.In the third part,the concept of micro-experiment,physical micro-experiment and life-changing physical micro-experiment is defined,and the characteristics and functions of the physical micro-experiment of life are described.The fourth part is the investigate the status quo of the application of physical experiment in the teaching of junior high school.It’s by the questionnaire surveys,interviews and research methods.This investigate provides practical basis for physical experiment design and application of research.The fifth part is the design research part,which gives the design principles and designideas,and enumerates the 12 life-changing physical micro-experiments designed by the author.In the last part of the paper,we design the application cases of the physical micro-experiment and give some suggestions.In the end of this paper,I hope our work can play a role in promoting which in the life of physical experiment of theory and practice research,as well as the micro physics experiment resources enrichment and development.
