| Physics is an experiment-based science.The physics curriculum at compulsory education stage consists of two parts: scientific inquiry and scientific content.Scientific inquiry includes scientific experiments and inquiry activities;scientific content includes physical concepts and physical laws.Both of them are the results of human exploration of nature.Therefore,the experiment is not only a potentially effective teaching method,but also an extremely significant teaching content.It should occupy an important position in daily teaching.However,in traditional classroom teaching,there are contradictions between less class hours and more tasks,large class teaching and tiny equipment.Due to the nature of the physics experiment itself,many important experiments can not be displayed in the classroom,or fail to achieve the expected experimental results.Therefore,the demonstration experiment teaching is difficult.At the same time,due to the irreversibility of physics experiment teaching,students occasionally fail to keep up with the progress of the class,which will lead to many problems in their experimental operation.The Internet offers more possibilities for education.‘Internet + Education’ promotes the integration of information technology and teaching,and promotes the development of microlecture,which not only enables learners to share high-quality educational resources,but also improves the efficiency of physics experiment teaching.The physics experiment microlecture empowers the educators and at the same time increases students’ interest in physics learning.However,the existing microlecture lacks research on the content of physics experiments in middle schools.Today,when the microlecture shifts from theoretical research to practical research,we must pay more attention to the development of the microlecture content of the middle school physics experiment to meet the needs of teachers and students.Under the background of the normalization of Internet education and the balanced development of compulsory education,we conduct follow-up interviews and questionnaire surveys on the current situation of the middle school physics experiment teaching in the poverty areas in southwest China,the status quo of the implementation of physics experiments,and the needs of teachers and students on the physics experiment microlecture,Then we analyze the feasibility of the middle school physics experiment microlecture.We also study the current situation and the application basis of the physics experiment microlecture in China.At the same time,through the literature analysis method,we study the research status and theoretical research basis of the physical experiment microlecture at home and abroad.It not only defines the concept of “Microlecture” and “Physical Experiment Microlecture”,but also expounds the theoretical basis and characteristics of the middle school physics experiment microlecture.Based on the theoretical basis and application basis of the physics experiment microlecture in middle school,we determine the design principles,content selection and classification,development technology and production process of the physics experiment microlecture.Then,we carry out case development on three types of experimental microlecture: student physics experiment microlecture,demonstration experiment microlecture and extended experimental microlecture,and we also put forward relevant suggestions for the teaching use of each microlecture.Finally,we combine the research results with reality of the middle school physics curriculum,providing an outlook of the future of the design,development and application in the middle school physics experiment microlecture,and give suitable suggestions. |
