Research On The Application Of Video In The "Problem-based Teaching" Of High School Geography Teaching

With the promulgation of geography curriculum standards for general high schools(2017 edition),it is emphasized to deepen the application of information technology.Teachers in the design and conduct the teaching activities,to make full use of Internet resources,consciously embodies openness of the Internet;New requirements are put forward in the process of teaching,that is,"pay attention to question-based teaching,question-based classroom".In order to find the convergence point between Internet resources and geography "question-based teaching",we can find the mutual benefits between the two.Firstly,through literature research,the author defines and interprets the connotation of "video teaching" and "question-based teaching" in geography.Second,respectively from the perspective of students and teachers,using the questionnaire survey and interviews,obtain first-hand data survey,understand the video application in the high school geography "problem-based teaching" the status quo,explore the video was applied to the high school geography "problem-based teaching" the feasibility and significance,as the study provides the basis of the feasibility and necessity.Thirdly,the application of video in geography "problem teaching" is studied and discussed,and three aspects of application principles,implementation procedures and application strategies are proposed.Firstly,it points out that the application of video in the "question-based teaching" of high school geography should follow five principles: authenticity of situation,scientificity,pertinence of content,thoughtfulness and appropriateness.Secondly,the implementation program of video in high school geography "question teaching" is analyzed to provide references for the application steps and procedures of video in geography "question teaching",which mainly includes four main steps: using video to reflect real life scenes and present "problem situation";Based on the "problem situation" and combining the teaching objectives and contents,the "problem" is put forward.Extract video information,construct knowledge independently,and solve "problems";Teaching effect feedback and evaluation.Finally,focusing on the fitting point of video selection and question design,five implementation and application strategies of video in "question-based teaching" of high school geography were proposed: selecting video that conforms to the teaching content and creating the real situation of geographical problems;According to the requirements of curriculum standards and teaching objectives,set up the problem chain and integrate "problem solving";Design and propose the problem of bad structure based on complex real situation;Respect students' subject status and put forward "problems" that can be explored from the perspective of cognitive conflict;Play video to moderate,do not usurp the host,put the cart before the horse.Fourth,through the case analysis,from the curriculum standard changes and the need for teaching content to illustrate the case selection reasons.From the course content and concept analysis,video problem situation presented in the problem design,teaching process design and implementation,practice effect analysis and evaluation of the four aspects to show the video applied in the geography "problem teaching" teaching implementation process and practical application,to provide a reference for the actual teaching operation.
