Research On The Application Of Video Resources In Junior High School Biology Teaching

Since the information age,the superior multimedia function and the convenient network resources have provided the enormous convenience for the teaching.Video resources with its intuitive,specific,and other features,much of the students like.In practical applications,many problems are troubling us.How to quickly and efficiently screen out the high quality,suitable for biology teaching video resources from the massive resources of network,how to edit the video resources and how to use them scientifically.Therefore,this paper attempts to study how to use video resources to improve the junior high school students' learning attitude to biology,how to use video resources to achieve the effective promotion of teaching effectiveness.In this paper,based on the study of scholars,combined with their own teaching experience,summed up the five major supporting role of video resources: first,it is conducive to the mobilization of students' learning interest.Second,it is to help students to understand the knowledge.Third,it is enrich the teaching content,expand the students' vision.Fourth,it improves the experimental teaching effect.Fifth,it improves affection.According to the data,the four principles that should be followed in the application of video resources are sorted out: the principle of subjectivity,the principle of effectiveness,the principle of moderation,the principle of scientific.This paper introduces the source of the video resources.The application of video resources of junior high middle school in biology teaching through the questionnaire survey and interview of the current situation and existing problems were analyzed,aiming at the existing problems,put forward specific countermeasures,action and in actual teaching,in the design,practice and reflection in the improvement of video resources application.Presents a representative case of teaching process,in the end of the paper the feedback effect again through the questionnaire survey on Application of video resources,found the application effect through the study of the improved video resources increased in the original basis.At the end of this paper,we put forward the conclusions,shortcomings and Prospect of the research,how to play the length of video resources is more reasonable,how to solve the contradiction between hours and long time.
