Development And Application Of Video Resources In Junior Middle School Biology Teaching

Video resources are a kind of audio-visual resources and a sort of valuable educational resources in biology curriculum resources which can give people a visual impact and feel on the spot.The combination and application of video resources and biology teaching is a measure to optimize education and improve teaching efficiency.However,video resources have a great variety of sources,and how to effectively organize,reasonably edit and make full use of video resources is an urgent problem to be solved.Based on this,the purpose of this study is to excavate video resources that can be used as curriculum resources in video resources and biology teaching,explore the principles and functions of its in teaching,in order to enrich the curriculum resources and strategies of biology teaching in junior high school,and combine with biology teaching,changing learning attitude and improving students' learning ability and efficiency through the application of relevant video resources.For a start,through consulting and analyzing the literature to research Video resource teaching and summarize the research status of video resource teaching.After that,interviews with teachers and reaction of students in traditional classroom teaching in practical schools were conducted to analyze the application status and existing problems of video resources in biology teaching of junior high school.In view of those,this paper puts forward the specific countermeasures for the development and application of video resources.Firstly,the selection principle,access way and processing procedure of video resource are introduced.And then based on the clear purpose of the teaching theme;Combine teaching with broadcasting,pay attention to students;Effective,timely and appropriate information;Creating situations and improving teaching effectiveness;Grasp the opportunity of effective application,choose the right way to play five aspects of rationalization of the application of video resources practice strategy.It is put into practical teaching to develop a usable video resource base by taking the biology textbook of the eighth grade of Phoenix Education edition as an example,finally.The application of video resources in junior middle school biologyteaching is implemented in five different teaching processes: introduction,teaching of new knowledge,discussion,acceptance and inquiry.After implementation,the application effect of video resources in junior middle school biology teaching is comprehensively feedback from classroom observation method,questionnaire survey method and interview method.The research found that the application of video resources has a positive effect in stimulating students' interest in learning,arousing their enthusiasm in learning,helping students understand the learning content,deepening memory,expanding horizons,training students' thinking,and touching students' emotional hearts.In the end,this paper summarizes and reflects on the whole research.
