Research On The Application Of Micro-video Resources In Biology Teaching In Junior Middle School

Educational informatization is a strong support for promoting the modernization of education.At the same time,one of the characteristics of educational informatization is the deep integration of educational technology and teaching processes.Mooc,micro-class,flipped classroom and hybrid teaching and other new teaching modes emerge at the right moment and are becoming practical.“Micro video” is a form of resources,which can be used in entertainment,teaching and business.Micro video is short,concise,targeted,and can specifically display the characteristics of teaching content.It can not only achieve teaching goals,but also meet the physical and mental development of students.This research focuses on how to obtain and process appropriate micro-video materials that which can be used in biology classroom teaching by using literature research,questionnaire survey and case analysis methods.The research contents are as follows:(1)The research status of "micro-video","micro-video teaching" and "micro-video biology teaching" was understanded by literature retrieval.The current situation of the application of micro-videos to assist junior high school biology classroom teaching was investigatedby questionnaires.Most biology teachers hold a positive attitude and have high expectations for micro-video teaching.However,there are few complete micro-video resource libraries,and it is difficult for teachers to obtain suitable resources.So micro-video teaching has become an ‘ideal teaching method’which is difficult to practice in practice.(2)This study summarizes the main ways of obtaining micro-videos and the processing methods of micro-video resources.(3)Taking the People’s Education Edition version of Biology as the object,this paper firstly analyzed the course content and learning situation,and then carried out micro-videoassisted teaching case practice for the for introduction,breakthroughs in major difficulties and experimental demonstrations respectively.The results show that mico-video teaching has a significant effect on improving the teaching effect.(4)Teaching resources of micro video were organized.These resources are suitable for teachers which use Biology(People’s Education Press,Book A and B of Grade 7)as teaching materials and may provide valuable suggestion for front-line teachers.
