Teaching Aid Production And Teaching Application Based On The Conveyor Belt Model

The new curriculum reform makes physics teaching pay more attention to experiments and development experiments,and encourages the use of existing materials to produce effective teaching aids.In this context,combined with the practical problems of teaching to study the production of conveyor belt teaching aids applied in teaching.In the process of research,literature research method and summary method were used to understand the development of research topics during the initial research period,investigation method and interview method were used to carry out the preliminary work,and practice method was used to carry out the actual research operation.This paper is devoted to the production and teaching research of conveyor belt teaching aids.At the beginning,the main content is to elaborate the significance of self-made teaching aids research,the realistic background,the specific status quo and the corresponding realistic purposes.Following is a detailed introduction of the theoretical part of homemade teaching aids,including the definition of relevant concepts,role,requirements to be met in the production process,some strategies to be followed in the development process and some methods to be adopted in the production process.Next is the most important part of the paper,which discusses the process of teaching research.The students’ understanding and application of the conveyor belt can be obtained through the conveyor belt test in the early stage.The interviewed teachers and students can learn about the situation of the learning conveyor belt and their expectations and suggestions for the production of the conveyor belt teaching aids.The medium-term teaching and research is mainly to make improved conveyor belts.Later teaching and research is mainly to design the experiment with the conveyor belt as the carrier,and find a student of extracurricular activity class to use the device to complete the experiment.In addition,several students and teachers are interviewed to find out their feelings and construction after using.The main results of this study are as follows:(1)Through the test and investigation of conveyor belt knowledge,it is found that students are prone to make mistakes in judging the direction of friction,failing tounderstand the conditions of acceleration and deceleration of objects,and easily ignoring the relationship between dynamic friction coefficient and tangent value of inclined inclination angle in the question of inclined conveyor belt.(2)Production of conveyor belt teaching aids.The functions of conveyor belt teaching aids include adjusting the rotating speed,rotating direction and inclination of conveyor belt and inclined plane,displaying the rotating speed of conveyor belt.(3)After practical operation in extracurricular activities class,students in extracurricular activities class can understand the function of conveyor belt teaching aids and learn to use conveyor belt teaching aids,and use conveyor belt teaching aids and sensors to complete some experiments.Through the production and teaching research of the conveyor belt model teaching aids,we can draw the conclusion that the use of the conveyor belt teaching aids can improve the teaching effect of teachers;for students,it can improve students’ interest in learning and deepen students’ grasp of corresponding knowledge.Manual operation experiment can improve the practical ability;for the relationship between teachers and students,it can shorten the distance between teachers and students.
