Applications of Digital Archival Geographic Information in K12 Education Department of Geography , National Taiwan Universityjinn-Guey Lay 2009PNC2009/10/08
Introduction • The National Digital Archival Program has accumulated over 3 million pieces of digital materials. • Maps and remotely sensed imagery are subjects of inclusion in archives. • Digital archival geographic materials reflect spatial and temporal dimensions of Taiwan’s geography and history. • This presentation illustrates the applications and potential of these digital archival geographic materials.
Types of geographic data in digital archives • Aerial photos • Old topographic maps • Historical maps • Spatially referenced tabular data • Old photos
Role of GIS in K-12 geography • Communication tool • GIS as a visualization media • Mapping and analytical tool • for solving geographic problems • Data management tool • GIS provides a platform that facilitates the integration and manipulation of geographic data.
Benefits of using GIS in K-12 • Improving the quality of learning in the classroom, • Widening the scope of teaching, • Helping children transit into an information-rich society, • For educators seeking new technologies and concepts to enhance the quality of education, GIS appears very promising in both conceptual and practical aspects.
Problems of GIS application • Training of teachers, • Curriculum integration, • Purchase of equipment, • Provision of curriculum materials.
Actions taken by the ASPA Program • For better application of these materials in K12 education, the Academic and Social Promotions and Application (ASPA) Program Office conducted the following tasks: • Compiling geographic data: converting analog materials to digital data and integrating them to geographic datasets. • Development of course modules: revealing the geographic and historical meanings of places; • Holding workshops: introducing the above mentioned modules to teachers all over Taiwan.
Data compilation • Scanning • Geo-referencing • Digitizing • Associating spatial and attribute data
Map-making • Hundreds of maps have been made over these two years. • Subjects of maps include: environmental change, population, land use, and names of places. • The application of these maps in K-12 education has been identified.
Development of sample modules • Studying curriculum standards and identifying topics for GIS inclusion • Design of course outline • Technology should be used in classrooms to support the primary objectives of learning • Too much content and too little time • The purpose and approach of introducing GIS into geography courses need to be clearly defined
Sample Result: Revitalizing Old Maps • Using the digitizing and geo-referencing functions of GIS, an old map of 1874AD was converted into digital map layers. • These map layers can be flexibly integrated with modern geographic data and reveals the history and geography of Taiwan.
Application of GIS: Urban Growth of Taipei • Old maps ranged from 1895 to date were scanned and digitized so that the urban sprawl of Taipei can be identified and analyzed.
Result and discussion • Hundreds of geography and history teachers have participated workshops of DAGI applications. • The value and potential of DAGI are highly regarded by these teachers. • Further promotion of DAGI applications to general teachers are desired. • Approaches and channels for dissemination need to be identified. • Web Map Service (such as Google Map/Google Earth) possess great potential for future promotion.
Conclusion • Introducing DAGI to K-12 will greatly enhance the value of digital archive program. • Application of DAGI in K-12 education is very promising. • Future promotion requires the collaboration of experts from GIS, pedagogy, and other relevant fields
