A Study On The Evaluation Of Film And Television Resources In The Application Of Biology Teaching In Junior Middle School

With the fast development of information technology,the curriculum reform of biology education is also advancing.All kinds of new teaching media and teaching ideas are displayed in the biology classroom.Film and television resources,as a kind of teaching media that can meet both visual and auditory needs,have been widely used in middle school biology classroom.Although the application of film and television resources has become more and more common,it has also triggered new thinking: how is the application of film and television resources in biology teaching in junior middle school? How to apply is good? How to optimize its application? To solve these problems,we need to deeply explore how to evaluate the application of film and television resources in biology classroom.Developing a set of evaluation scales that can scientifically evaluate the application effect is conducive to promoting the improvement of teachers' professional ability and the in-depth integration of film and television resources and biology teaching.Firstly,this study expounds the research background,summarizes the research situation of film and television resources in the field of education at home and abroad,and determines the research object and scope through reading and analyzing the literature.It also takes biological learning theory,constructivism learning theory,experience tower theory and social learning theory as the theoretical guidance,which lays a foundation for the evaluation and research of film and television resources in the application of biology teaching.Secondly,the core of the research is the process of constructing the evaluation index system.This paper mainly uses Delphi method to consult 10 experts in the field of biology teaching.Through the quantitative and qualitative analysis of two rounds of questionnaire data,the evaluation index system of film and television resources is finally established,and the weight of each evaluation index is evaluated by expert estimation method.Finally,the reliability and validity of the evaluation index system are tested.Based on the constructed film and television resource application evaluation index system,this study invited five front-line teachers to score the junior middle school biology excellent courses with ministerial and municipal award-winning levels on the "one teacher,one excellent course" platform.The scoring results are used as the test of the consistency of the evaluation index system.According to the relevant opinions and suggestions of raters,this paper puts forward the optimization strategy of the application of film and television resources in junior middle school biology teaching.Through the research,this paper constructs the evaluation index system of film and television resources in the application of biology teaching in junior middle school,including three primary indicators: content design dimension,teaching implementation dimension and goal achievement dimension;Eight secondary indicators: design basis,video content,video quality,presentation mode,presentation timing,teaching objectives,teaching effect and student development;24 tertiary indicators.
