Application Research Of Micro Video In The Teaching Of Biology Concepts In Junior Middle Schools

With the rapid development of information technology,science and technology are changing with each passing day.Under the background of "maintaining deepening education reform,upholding the new concept of educational development,and accelerating education modernization",Teachers should take the initiative to control information technology,make good use of new technologies,adapt to the development of the new era,and actively carry out effective education and teaching.As a part of information technology,“video” plays an important role in education and teaching.The Compulsory Education Biology Curriculum Standards(2011 edition)lists 50 core concepts of biology and clarifies the specific learning objectives of junior high school biology.The effective application of micro-video resources in the teaching process of junior high school biology concept helps students understand the core concept knowledge of biology,open up the field of vision,stimulate interest in learning,and improve the literacy of biology.Based on this,the author carried out research on the application of micro-video in the teaching of important concepts in junior high school biology.This research mainly uses literature research method,questionnaire survey method,interview method and case analysis method.Firstly,the literature research method is used to summarize the related concepts of micro-video,teaching micro-video,concept teaching,related theories and research status at home and abroad,which provides an important basis for the research.Secondly,using the questionnaire survey method and the interview method to conduct a preliminary investigation on the status quo of the concept teaching of junior high school biology teachers applying micro video,to understand the application status and problems of micro video resources in the teaching of junior high school biology concepts: First,teachers' realizing and understanding of micro-video and its application in concept teaching are not in place;Second,the micro video resources available to teachers are not rich enough;Third,there are differences in the level of conceptual teaching design for teachers using micro-video;Fourth,teachers have shortcomings in the processing technology of micro video.Then,propose corresponding solutions: First,deepen teachers' understanding of the concept teaching of applying micro video resources;Second,enrich the micro-video resources related to the teaching of biological concepts and strengthen the construction of curriculum resources;Third,actively carry out teaching and research activities to improve the application of micro-video to the conceptual teaching design level of teachers;Fourth,carry out information technology capability training to enhance the ability of teachers to produce and edit micro-video.Then,combined with the collected quality examples,summarize the strategies for applying micro-video resources in the teaching of junior high school biology concepts.Finally,design a typical teaching case,apply the micro-video resources to the practice of junior high school biology concept teaching,and evaluate the effect,and summarize the application of video resources for conceptual teaching.This paper aims to provide some suggestion for the first-line biology teachers to apply micro-video resources to the core concept teaching of the subject through the application of micro-video in the teaching of junior high school biology concepts,In order to promote the deep integration of information technology and classroom teaching,and improve the effectiveness of junior high school biology classroom teaching.
