A Study On The Application Of Film And Television Resources Of Science And Education In Biology Teaching In Rural Junior Middle Schools

The main purpose of biology curriculum in basic education is to improve students' biological science literacy in China,and teaching with scientific and effective curriculum resources is an important teaching means to improve students' biological science literacy.As an off-campus science curriculum resource,science and education film and television resources play a great role in optimizing the effect of biology teaching and improving students' biological science literacy.However,it has not been fully applied and valued in rural biology teaching.How to apply it scientifically and effectively to the practical teaching of rural biology is a research subject with both epochal and practical.The purpose of this study is to optimize the effect of biology classroom teaching in rural junior middle school by using the film and television resources of science and education.Based on constructivist teaching theory,Dale's "The cone of experience" theory,multiple intelligence theory as the basis,using literature research,questionnaire and interview survey,case analysis,practical demonstration and other research methods,after combing the research status of science and education videos resources in teaching application at home and abroad,summarizing the relevant knowledge of science and education film and television resources,and determining the research methods and contents of this subject,the researcher used methods of questionnaire and interview,aiming at biology teachers in Dushan junior middle school and teachers and students in Dushan No.2 middle school,and analyzing the present situation and existing problems of science and education film and television resources in the application of biology teaching in rural middle school.Based on the teaching present situation and existing problems,the author puts forward the application strategy of science and education film and television resources in biology teaching in rural middle school,andexplains it by case.Then,the author select "infectious disease and its prevention" and "human reproduction" two sections to carry on the concrete teaching case design and analysis;finally take Dushan second middle school as an example to carry on the practice teaching,and carries on the analysis to the practice teaching effect.The study's results showed that:(1)The Dushan County biology teacher held a positive attitude towards the science and education film and television resources for its application in biological teaching,but the related theory knowledge of teaching and the integration of vedio resources of the rural biology teacheris is weak,The ability of teachers to collect,process and apply film and television materials needs to be improved,and problems such as improper material selection,chaotic teaching pace and poor teaching effect will occu in the process of teaching applicationr;(2)Many students welcome the use of film and television resources of science and education,believing that it has a positive effect on learning interest,learning attitude and learning methods.Through a semester of teaching practice,it is concluded that science and education video resources can improve students' interest in biology.and have a positive impact on the concentration of learning in classroom,the understanding and remembering of knowledge,the enthusiasm of analyzing problems,the ability of autonomous learning,the sublimation of the emotion,attitude,values,expanding horizons and improve grades,etc have a positive impact.(3)This paper put forward the strategy of applying science and education video resources for biology teaching in rural middle schools,grasp the principles of objective,typicality,adaptability,moderation and timeliness in the selection of resources;In the teaching links such as introduction,key and difficult points teaching and scientific inquiry,it isnecessary to carefully design the classroom teaching process,select the best video broadcast time,the appropriate broadcast mode and the scientific effectiveness principle of information.Pay attention to the application of not far-fetched,do not dominate the main,do not video dominated the classroom,put forward to teaching optimization Suggestions that increase the rural teachers,teaching equipment investment,improve the quality of biology teacher in film and television,strengthen the supervision of education departments and provide the assistance of family education,establish a database of film and television resources for science and education.
