Research And Practice Of Physics Experiment Teaching In Junior High School Under The Background Of Modern Educational Technology

The current speed of technology development is faster and faster,education should also follow the pace of technology.Combined with the influence of the new curriculum education concept on the junior middle school physics experiment teaching and the specific problems encountered in the process of experiment teaching since the author served as a teacher in a middle school in Nanchang City,Jiangxi Province,this paper carried out research and practice on the junior middle school physics experiment teaching under the background of modern educational technology.Modern educational technology refers to the use of new teaching means and new teaching content to help students solve various difficulties in the process of learning,but also to help teachers to achieve better classroom teaching results.In physics experiment teaching,modern educational technology mainly includes multimedia technology,mobile intelligent equipment,virtual simulation physics laboratory,micro-classroom,cloud classroom and other advanced educational means.On March 19,2021,Jiangxi Provincial Education Examinations Institute released the instructions on the junior middle school academic proficiency examination.The total score of physics subject was reduced from 105 to 85,but the score of "experiment and inquiry" remained unchanged,with the score of 28 remaining unchanged,and the score of 5 remaining unchanged for "students’ hands-on experiment".It can be seen that experiment occupies an important position in physics.In junior middle school physics teaching,experiments can make students better understand the concepts and laws of physics,cultivate students’ skills of scientific inquiry,and then stimulate students’ interest in learning physics.For junior high school students,experiments are an important step into the physical world,which is of great help to the establishment of the world outlook.This paper mainly studies the changes brought by integrating modern educational technology into junior middle school physics experiment in the actual physics classroom to teachers’ "teaching" and students’ "learning".The author through reading relevant literature,to the effect of the class of modern education technology and application,research and analysis in practice school of modern education technology in junior middle school physics experiment teaching practice,this article will through the three teaching cases to tell the importance of modern education technology in experimental teaching.First,in exploring the imaging law of the convex lens,through the simulation laboratory,by moving the mouse to change the distance between the object and the lens to get the imaging law of the convex lens;Second,in the exploration of the cause of buoyancy,through the self-made teaching AIDS combined with the teaching assistant of Sivo demonstration,by comparing the deformation degree image of rubber film on each side of the cube,the cause of buoyancy is obtained.Third,in the exploration of lever balance conditions,the lever demonstration instrument and multimedia technology are combined to make students intuitively understand the lever arm and balance conditions.In the above three cases,the author respectively used virtual simulation laboratory,mobile intelligent equipment,cloud classroom and other educational technologies to transform the traditional boring experimental teaching into vivid,interesting and visual teaching.Traditional experimental teaching is often due to the lack of experimental equipment,old experimental equipment or experimental phenomenon is not obvious and other factors,leading to teachers can not really carry out experiments,instead of experiments,phenomena,conclusions,which greatly violates the rules of teaching.Integrating modern educational technology into junior middle school physics experiment teaching can well solve the above limitations.
