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

With the development of modern information technology,education,as a kind of Social practice,will be transformed by the development of computer and internet.In addition,people are gradually entering the " micro-era",and micro-blog information,micro-novels and micro-movies can be found everywhere in life.It is in this environment that junior high school students grow up,and their ideological state and behavior have been deeply influenced,with changes in learning content and ways.Micro-video has simplified and diversified contents,vivid pictures and music matched with it,which can quickly attract students' attention and stimulate their interest in learning.Therefore,the application of micro-video in teaching can better meet the needs of junior high school students in modern information technology.This research mainly adopts the methods of literature review,observation and research,text analysis and lesson analysis.Based on the content of biology in junior high school of Shandong science and technology publishing house,excellent micro videos are collected and analyzed.Through the observation of the lead-in link,new teaching link and consolidation link,the problems were found and the application suggestions were put forward.Combining with the application suggestions,this paper designs and evaluates the application of micro-video in junior high school biology teaching.Firstly,based on the analysis of the function,characteristics,sources,editing and production of micro-videos,this paper collected micro-videos related to 50 important concepts in the curriculum standard of compulsory education biology,and then made text analysis of micro-videos,including the source and editing of micro-videos and their basic content brief introduction.Then,go deep into the front-line classroom,watch the video of high-quality class,and use the self-made observation scale to observe the application of micro-video in the introduction,new teaching and consolidation of junior high school biology teaching.Found a series of problems,such as scientific errors and incompleteness of appropriateness.And put forward application suggestions in micro-video level and teachers level,such as scientific nature should be correct,appropriateness should be comprehensive,formality and innovation should be moderate,and simplicity should be moderate in micro-video level.At the teacher level,first,should improve the quality of questioning and second,should improve the consolidation level.Finally,design the lesson example about the application of micro video,which is divided into two parts: first,design the lesson about the application of micro video in different teaching links;Then take the content of the section " transpiration of plants" as an example,design the lesson of the application of micro-video,and evaluate it by experts and first-line excellent teachers,and reflect on it according to the evaluation.
