Enhancing Teaching and Learning Practices with Digital Mapping Approaches
On Monday, November 7, Professor Diana Sinton, the Director of Spatial Curriculum and Research at the University of Redlands, came to Georgetown University to speak about the way in which scholars and students in higher education can integrate mapping tools and GIS software within their research and class projects. Sinton described four approaches to designing mapping projects in higher education:
- (i.) maps as organizational templates, points, lines, and areas displayed in their “true” geographic space;
- (ii.) maps as a tool for spatial analysis, not just their graphic representations, but a focus on measured and descriptive characteristics;
- (iii.) maps as metaphors for organization and navigation;
- (iv.) graphs and charts that display geographic data with alternative representations of space.
For learning and scholarship to be enhanced by these strategies, however, Sinton urged scholars to create a foundational set ofcritical research questions before choosing the mapping approach and software for their particular research projects.
i. Maps as organization templates: Is your research question a "what" or "where" question?
The use of maps as organizational templates is one of the most common approaches used by scholars. This method identifies where and what a particular phenomenon is by superimposing visual and quantifiable data over geographical templates, most commonly with GoogleMaps; this method is also known as a Google Mashup.
At Trinity College, a group of first year students in the course “Invisible Cities” used an organizational template approach to map food resources, historical sites, youth hangouts, and educational resources in the Hartford community using GoogleMaps markers. This approach let new students explore the city’s resources, as well as helping them understand the spatial layout of the city using a familiar platform.
Similarly, foreign language classes at Fairfield University are now requiring students to explore and annotate maps in a foreign language to prepare for their study abroad sessions. In Diana Sinton and Jenni Lund's book,Understanding Place: GIS and Mapping Across the Curriculum, Goldfield and Kurt Schlichting, professors in the French department at Fairfield University, wrote a chapter titled, “Foreign language and Sociology: Exploring French Society and culture,” which highlights the way GIS can support foreign language study.
Organizational templates can also be used for social justice and humanitarian causes. For example, crisismappers.net provides open source mapping services to users interested in supporting “effective early warnings for rapid response to complex humanitarian emergencies” (Crisis Mappers Network). The Libya Crisis Map was launched in April 2011 by the Office for the Coordination of Humanitarian Affairs (OCHA). The map geo-locates reports on armed confrontations, attacks on protected persons, needs, and more.
Organizational templates can also used for more advanced purposes, such as cultural and historical analysis. The University of Sydney’s history project,Digital Harlem, is a map that contains cultural and qualitative meta-data gathered from legal records, newspapers, and archives and historical maps between 1915-1930. The user can use the search tool on the side of the map to look for specific information about events (e.g. dance, baseball games, arrests, etc.), people, and places in Harlem. Professor Stephan Robertson, one of the creators of the project said, “I had a longstanding curiosity about doing something with online mapping, and since we were studying place, it seemed like an opportunity to see what was possible.” The project was formulated in the Department of History at the University of Sydney, and the Technical work was implemented by the Archaeological Computing Laboratory (ACL), at the University of Sydney. Sinton noted that it is essential to collaborate with a mapping specialist in order to help guide the technical side of the project. In all of these examples, Sinton highlighted that the organizational template is mainly used to identify the location of phenomena in the world using real world geographic data. The Digital Harlem mapping project gets closer to asking why objects are in a particular space, but the mapping approach for spatial analysis is a tool used to better answer this question.
ii. Maps as Spatial Analysis: Asking Why?
Spatial analysis considers the measured and descriptive characteristics of a map. Professor Ann Knowles in the Geography department at Middlebury College, started a project called, “Visualizing Gettysburg.” Knowles started her mapping project with a question: What would the confederate general Robert E. Lee actually see during the battle of Gettysburg? Knowles and her students created a view shed of General Lee’s position from a “point 75 feet above the terrain -- the distance from the ground to the cupola floor plus Lee’s eye-level standing in his boots.”
A Habitat for Humanity map, created by Professor Christine Drennon in the Urban studies department at Trinity University, explores and analyzes how the spatial layout of historical habitats, such a museums and national historic landmarks in San Antonio, impact the flow and structure of communities.
iii. Maps as a metaphors for organization and navigation.
Maps as metaphors highlight the way in which humans have become naturalized to use the Google navigations tools (e.g. zoom, Google Street View) on a daily basis. Google navigation tools are now used in fractal visualization and online art gallery tours to help guide the viewer through non-geographic space. For example, Google is now powering an Art Project that explores museum space on the Internet (Figure 5). This project underscores how “pervasive” google tools have become in our everyday lives and how easily they can be used in teaching and learning practices.
iv. Graphs and Charts that display geographic data but with no pretense of using “True” geographical space.
To exemplify this method, Sinton used the “Obesity Epidemic Graph” map. This map shows the lowest obesity rates to highest obesity rates in the United States using T-shirt symbols, rather than using the states geographic visualization with GoogleMaps. Graphs and charts are great ways for students and scholars to explore alternative visualizations of geographic data in an aesthetically pleasing interface.
Historically, GIS tools have been used for capturing space, but as Sinton’s examples demonstrate, scholars can now explore new ways to add cultural data to spatial tools to capture the essence of place. In closing, Diana Sinton demonstrated useful teaching strategies in GIS, such as the power of side by side comparisons and the benefits of generating familiar frames of reference using maps. Sinton also urged her audience to think critically about mapping data. As more and more mapping projects are launched, scholars need to question the accuracy and consider the source of the data. Lastly, there are many rationales for incorporating GIS into higher education, ranging from helping students compete in the marketplace to its useful and rich insights for teaching and learning practices, but it is important to establish a research question and a team of GIS specialists before a project can begin. Many higher education institutions across the United States have created centers for spatial learning:
- Stanford University, The Spatial History Project
- University of Pennsylvania, Mapping Dubois Project
- Yale University, Map Collection.
- University of Redlands, Spatial Literacy Program
The Center for New Designs in Learning & Scholarship (CNDLS) was fortunate to have the opportunity to bring Sinton to speak. CNDLS staff members are currently gathering resources and working toward being able to support a wide range of GIS projects for teaching and research, in partnership with the Gelardin New Media Center.
