Research On The Creation Of Geographic Problems Situation Based On Geographic Information Technology

The advent of the information age puts forward higher requirements for talent training,students should be able to apply geographic information technology to analyze and solve geographical problems,the "General High School Geography Curriculum Standards" promulgated in 2017 proposed to deepen the application of information technology and attach importance to problem-based teaching,to make full use of geographic information technology,to create an intuitive,real-time,vivid geography teaching environment.At present,the creation of geographical problem situations and the research of geographic information technology to assist geography teaching have attracted the attention of scholars and front-line teachers,but teachers do not pay enough attention to geographic information technology when creating geographical problem situations,and the application is shallow,and they fail to give full play to the advantages of geographic information technology in creating geographical problem situations,so how to apply geographic information technology to the creation of geographical problem situations needs in-depth and systematic research.Based on the above background,this paper uses the literature research method to sort out and analyze the research status of geographical problem context creation,geographic information technology assisted teaching and geographic information technology assisted geographical problem situation creation at home and abroad,and clarifies the connotation of geographical problem situation creation and geographic information technology teaching function.Combined with the core concepts and theoretical foundations,the types of geographic problem situations suitable for geographic information technology are sorted out,and the advantages of geographic information technology in creating geographical problem situations are analyzed as follows: rich data resources and rich problem context data library;Powerful spatial analysis enhances problem contextual inquiry;Two-dimensional and three-dimensional visualization enhances the spatial sense of the problem situation.Through literature research and questionnaire survey,it is found that the main problems in the current problem situation created by front-line teachers based on geographic information technology are: lack of theoretical guidance;not knowing the source of the data;Insufficient operational capabilities;Inadequate design of the problem;Less emphasis is placed on contextualizing local and current issues.In view of the above problems,combined with relevant theories and literature research,this paper constructs the steps of creating geographical problems based on geographic information technology,discusses the scientific principles,hierarchical principles and student subjectivity principles of creating problem situations based on geographic information technology,and proposes optimization strategies: studying course standards and teaching materials to strengthen the design of situational problems;Understand the data sources of geographic information technology and establish a resource library of problem situations;Master the simple operation of geographic information technology to enhance the exploration of problem situations;Focus on local and current events,and create diverse problem situations.Finally,the lesson design was carried out.In order to provide some theoretical guidance and practical reference for front-line geography teachers to use geographic information technology to create geographical problem situations.
