Research On The Evaluation Of Video Resources In The Application Of High School Geography Teaching

With the development of information technology and the further promotion of the new round of geography education curriculum reform,the changes in the field of education are changing with each passing day,and various teaching concepts,teaching media and teaching methods are pouring into the geography classroom.As a kind of modern media,video resources have been recognized and widely used by geography teachers.The universality and universality of the application of video resources show that geography teaching keeps pace with the times,but at the same time,it also leads to thinking:is video resources well used in geography teaching?How to use it better?In view of these problems,it is necessary to explore how to evaluate the video resources applied in middle school geography class,which is of practical significance to promote teachers to better think about and improve the ability to apply video resources.This paper discusses from three parts:The first part,starting from the background analysis,combs the current research status of geographic video resources at home and abroad,defines the scope of research,and determines the research subject.Based on geography teaching theory,constructivism theory,tower of experience theory and multimedia learning theory,this paper constructs the bridge between video resources and geography teaching,and strengthens the theoretical basis of the paper.The second part,take the evaluation index design as the core.First of all,from the evaluation concept and principle to standardize the evaluation index formulation behavior,through the classroom observation and literature analysis method from the geographical teaching requirements,media characteristics and the actual application of video resources three aspects of the evaluation index points,so as to build a preliminary evaluation index system of video resources in the application of high and middle school geography teaching.Secondly,on this basis,Delphi method is used to invite 12 relevant experts in the field of geography teaching.Through the quantitative and qualitative analysis of two rounds of questionnaire data,the evaluation index system of video resources is determined.Finally,the weight of each index in the application evaluation index system of video resources is determined by expert evaluation method.In the third part guided by practical application,three researchers are invited to grade the two classes by video based classroom observation.The consistency of the evaluation index system is tested according to the score,and the differences between the two classes are analyzed according to the scoring rules,so as to put forward the Optimization Countermeasures of video resources in the application of high school geography teaching.Through three parts,this paper finally constructs a perfect evaluation index system of video resources in the application of high school geography teaching,which includes four first level indexes:teaching objective dimension,content design dimension,teaching implementation dimension and goal achievement dimension;12 second level indexes:geographical practice,comprehensive thinking,regional cognition,human land coordination concept,design basis,video content and vision Frequency quality,presentation mode,situation creation,classroom atmosphere,teaching effect,student development;26 three-level indicators.
