The Applied Study On Micro-video In The Biological Practical Activities Of Junior High School

With the development of the new media,the modern information-based teaching methods has gone into many aspects of teaching and has become a large assistance to the present teaching reform,which also provides a great convenience to get the external information for students.Micro-video plays an important role in the process of teaching due to its flexibility,convenience and operability.In the biology extracurricular practice of junior high school,if micro-video is applied,it can stimulate students' interests,help students grasp the practice process better,reduce the difficulty of the practice,and cultivate the students' self-confidence.The main research purpose of this thesis is to use the micro-video to improve the effect of extracurricular practice and to improve the students' biological science literacy.In this research,the writer mainly uses the methods of literature,questionnaire,case analysis and empirical study,and makes an investigation and research on the extracurricular practice in which biology teachers in junior high school use micro-video,and understands the existing problems of micro-video in junior high school biology extracurricular practical application,and puts forward corresponding strategies according to the specific question.At the same time,the writer takes a biological version of Luke as an example,selects typical extracurricular practice,and with the help of micro video,designs practice activities to provide reference for the first-line teachers.First of all,through the questionnaire survey and interview,the writer concludes the status quo of the extracurricular practice and the problems of application of micro-video in biology extracurricular practice of the junior middle school:(1)the status quo of the extracurricular practice is not optimistic;(2)the teachers' understanding of the application of micro video in extracurricular practice is not enough;(3)there are the differences between different teachers' information literacy;(4)the teachers lack the understanding of developing and selecting the micro-video.To solve these problems,the writer puts forward the corresponding solution strategies:(1)to use micro-video resources to improve the effect of extracurricular practice;(2)to deepen the teacher sunder standing of theextracurricular practice to use micro-video;(3)to carry out the teachers' training to improve the ability of teachers to make the micro-video;(4)to clarify the principles of selecting the micro-video resource in the extracurricular practice.Then,the writer makes an analysis of the extracurricular practice in the Luke version in junior high school biology textbook,and on this basis,based on the advantages of micro-video application in the junior middle school biology extracurricular practice,the writer puts forward some concrete application strategies,which provides reference for biology teachers in junior high school to scientifically use the micro-video in the extracurricular practice.Finally,the writer selects the typical extracurricular practice,use the micro-video to design activities and make a practical research.Through the practice,the writer finds that using micro-video to make an extracurricular practice can improve students' enthusiasm;can help students to master the practice process smoothly and then improve the ability of their independent practice;can record the practice process and then help teachers to conduct a comprehensive evaluation.
