Research On The Design And Teaching Application Of Micro-Course Of Physics Experiment In Senior High School

"With the continuous development of micro-course as an educational resource,there are a lot of research literature on micro-course on China KnowledgeNet,and there is less research on micro-course of physics experiment based on the characteristics of experiment.Physics experiment is very important in high school physics teaching.It can cultivate students’subject literacy in an all-round way.However,there are some deficiencies in the related teaching of physics experiment in actual teaching.This paper provides more diversified teaching resources for teachers through the design and application of experimental micro-course.In this study,literature review,questionnaire survey,interview and case analysis were used to study the design and application of experimental micro-course.This research mainly includes the following parts:The first three chapters are the preliminary preparation for the research,define the relevant concepts,and classify the experimental micro-courses according to the concept and presentation form of the experimental micro-courses.Based on the mobile learning theory,mastery learning theory and constructivism theory,this paper summarizes the advantages and similarities of the design of experimental micro-courses on the internet,and explores the design principles and process of experimental micro-courses combined with the learning cognitive situation of senior high school students.Chapter 4 is based on the theoretical analysis of the first three chapters.According to the design principles and design process of experimental micro-course,four cases of experimental micro-course(including two self-recorded electrical micro-course and two network high-quality mechanical micro-course)are developed,which mainly include the design of teaching analysis and subject content Chapter 5,according to the needs of curriculum learning,applies the experimental micro-lesson cases of "Measuring Speed with Dot Timer","Exploring the Law of Vehicle Motion Speed with Time" and "Newton Tube" in different forms to actual teaching for effect analysis.Through theoretical and practical research,it is found that combining the actual teaching process with the perfect experimental micro-lesson can deepen students’theoretical knowledge.Understand and stimulate students’ interest in the operation of physical experiments.
