Research On Cultivation Of Geospatial Expression Ability Based On Information Technology

The deep integration of information technology and education emphasizes the cultivation of students' ability to use information technology to solve problems.It is an important way to improve students' geospatial literacy to cultivate students' geospatial expression ability based on information technology.By using the method of literature,this paper first summarizes the research status at home and abroad;secondly,it divides the expression of geospatial space into three dimensions: the expression of geospatial location,the expression of geospatial distribution,and the expression of geospatial relationship.Under this dimension,it further divides the level of geospatial expression;at the same time,it elaborates five spatial tables: language,image,mathematics,number and cognition On the basis of the connotation of the way of presentation,this paper analyzes the directional requirements of the cultivation of the ability of geospatial presentation on the application of information technology.In addition,according to the essence of the integration of information technology and classroom teaching,and the practical application of information technology in the geography classroom teaching,this paper divides the application of information technology in the cultivation of the ability of geospatial presentation into three levels:display level and teacher operation level Working level and students' operation level.By using the method of case study,taking the dimensions,levels and methods of geospatial expression,as well as the types and application levels of information technology as the main indicators,this paper has compiled the analysis scale of the application of information technology in the cultivation of geospatial expression ability",summed up the current situation of the application of information technology in the cultivation of geospatial expression ability,and obtained the Enlightenment from it First,from the perspective of the types of information technology,in addition to multimedia presentations,mobile terminals,apps and Google are mainly used Earth,information-based teaching platform;second,from the perspective of the application of information technology in different presentation levels,different information technology tools are applicable to different geographic spatial presentation levels;third,the application of information technology is mainly based on the display level and the operation level of teachers,so we should strengthen the application of information technology in the operation level of students,when limited by conditions,it can not reachthe operation level of students Teachers should guide students to acquire geographic information and express space through the application of information technology through problem and activity design.Based on the above research,this paper puts forward the cultivation strategy of the ability of geospatial representation based on information technology,including the representation of geospatial location based on Virtual Earth,the representation of geospatial distribution based on electronic map,the representation of geospatial connection based on mapping tools,and the cultivation of geospatial representation ability based on mobile terminals.Taking the representation of the geographical location based on Virtual Earth and the representation of the geographical distribution based on electronic map as examples,this paper designs a teaching case,and makes an empirical analysis on the training strategy of the ability of the representation of geographical space based on information technology.This paper discusses how to cultivate the students' ability of geospatial expression based on information technology.On the one hand,it is conducive to the theoretical construction of the way of cultivating the ability of spatial expression and the further deepening of the theory of computer-aided geography teaching;on the other hand,it is also helpful for teachers to improve the way of teaching and learning and improve the students' geospatial literacy.
