Design And Application Of Physics Experiment Micro-lectures For High School Students

With the rapid development of information and network technology,mobile phones,tablet PC and other emerging mobile communication devices spread all over the world quickly,and the products of the information age make it possible for people to have various accesses to knowledge and information.The network resources are increasing rich and abundant,which are changing people's lives and learning methods.Learning tools like Micro classes which use these mobile devices came into being,with the features of free from time and space.In order to solve the problems of experimental conditions,experimental sites and time limits in traditional experimental teaching,it is necessary to adopt the new curriculum reforms to change the students' learning styles and to cultivate students' ability of autonomous learning.This paper,which is based on the basic theories of micro-lecture designing,take two typical student experiments selected from the physics textbook of high school as examples to study the design and application of micro-experimental lectures.First of all,we studied and analyzed the traditional experimental lectures and micro-experimental lectures by retrieving and consulting,collecting relevant literatures and conducting researches and investigations.We found that the existing traditional experimental lectures are unable to meet the needs of students,and there are some shortages in the design of the existing micro-experimental lectures,and those experimental classes failed to meet the expected teaching effects.We also found that the main problems are there is no complete supporting exercises and the design of the micro-experimental lectures is plain and dull.In order to solve the problems in current micro-experimental lectures,the author puts forward new ideas and methods to improve the design and to make better micro-lectures.Then,based on the ADDIE model and the characteristics of high school students,this paper puts forward a teaching model which is suitable for the experiment of high school physics students.On this basis,two typical student experiments in high schoolphysics compulsory textbook are selected to conduct the teaching design.Teaching design mainly includes the curriculum analysis,main design,application and feedback,among which the main designing part includes teaching process,micro teaching plan,micro courseware and micro practices.Finally,through the application and study of the practices in a secondary school in Chongqing,the results of micro-experimental lectures show that the students' micro-experimental lectures can deepen the students' understanding of the experiment itself and help to cultivate the students' ability of autonomous learning.And to some remote schools which lacking of experimental equipments because of backward objective experimental conditions,micro-experimental classes could help students in a great deal.From the interview of the teachers there,we can see that they are satisfied with the micro-experimental lectures,and they also support the teaching methods of micro-experimental lecture.Therefore,the design methods and examples of the micro-experimental lectures presented in this paper have achieved the expected results,and we can see that it is practicable to apply the micro-experimental lectures.In addition,from the survey to the understanding and to the production of the micro-experimental lectures,there are also some shortcomings.Due to the modest shooting technology,the image quality is not ideal and the interactivity need to be further improved.But our goal is to keep moving to produce a full set of high school physics micro-experimental lectures of high quality.
