Construction And Application Of Geographic Remote Sensing Image Resource Database In Senior High School

With the continuous advancement of the new curriculum reform and the arrival of the educational information 2.0 era,the new teaching resource model of paper-electricity linkage is gradually called the inevitable trend of teaching reform.The geography curriculum standard for senior high schools(revised in 2017-2020)fully affirms the necessity of information technology in geography teaching,and pays special attention to the construction of various digital geography teaching resources based on geographic information.As the frontier achievement of the close combination of remote sensing and new technology,it contains great value of geography teaching resources in senior high schools and needs to be developed by geography teaching and research personnel.Constructing the remote sensing image resource database suitable for geography teaching in senior high schools is of great significance for enriching geography teaching content,changing classroom teaching methods,cultivating students’ core literacy in geography,promoting the development of teachers’ professional ability and deepening the modernization of geography teaching.This paper mainly adopts the methods of literature research,questionnaire survey and action research,focusing on "the construction and application of high school geographic remote sensing image database".The full text consists of seven parts.In the first part,the research background and current situation of this research topic are sorted out by using literature method,and the theoretical and practical significance of constructing high school geographic remote sensing image resource database is put forward.The second part mainly defines the concepts of remote sensing image,teaching resource database and remote sensing image resource database,and confirms that this research is carried out under the guidance of multiple intelligences theory,TPACK theory and "experience tower" theory.The third part is an overview of remote sensing images,clarifying the classification and characteristics of remote sensing images,and laying a theoretical foundation for building various types of remote sensing image resource database.The fourth part is the necessity and feasibility analysis of the construction and application of geographic remote sensing image resource database in senior high school.In the fifth part,the questionnaire survey method is used to analyze the current situation of the construction of high school geographic remote sensing image database by front-line geography teachers in actual teaching.The questionnaire shows that the obstacles encountered by teachers in the actual construction of database include their own lack of related technologies,tight teaching time,difficulty in processing remote sensing images according to teaching needs and limited access to remote sensing images.In the sixth part,according to the problems existing in the questionnaire,the author discusses in detail the basis,principles,steps and application strategies of constructing the remote sensing resource database in high school.In the seventh part,according to the basic framework of database building,it is determined that the Common Geomorphic Types published by People’s Education Edition Geography 1 will be used as the knowledge module to build the database.Taking Common Geomorphic Types as a case,practical teaching will be carried out,and the effectiveness of the database will be verified by qualitative and quantitative methods.It can be found that using the high school geographic remote sensing image database to assist geography classroom teaching has positive effects in stimulating students’ interest in classroom learning,creating a good classroom atmosphere,enhancing students’ spatial perception and forming geographic abstract generalization ability.
