Middle School students reading various geography text books during class in 1927, at the University of Chicago Laboratory School. Emphasis on memorization. Difficult to layer data.

1980s: Databases, Not Easy to Interpret

1990s: GUI, Visualization

These four layers might be part of one city's geographic dataset. The layers all contain features located within the city's boundaries, but each one represents a distinct "theme."

Map based problem solving has been done without digital tools for centuries.

Public Policy:Digital mapping is used to enable policy

makers to more easily detect patterns pertaining to:

- census demographics- public health concerns- crime- tax rates- transportation routes- pollution levels- real estate development- weather patterns- gas / electric power consumption- the impact of various types of natural and

human made disasters

- Determine who needs to be treated- Records based on home address on registration form- Notify areas with low vaccination rate / large population

ArcPad is designed for field teams who require GIS capabilities. It provides staff with the ability to capture, edit, display, share and analyze geographic information.

This map and the data behind it were compiled by Dr. Henry Niman, a biomedical researcher in Pittsburgh, Pennsylvania, using technology provided by Rhiza Labs and Google. The map is compiled using data from official sources, news reports and user-

contributions and updated multiple times per day. http://flutracker.rhizalabs.com/

How is digital mapping being used in classrooms?

• Learning about digital maps: - focus on learning the software- teacher is “sage on the stage”- focus on procedural tasks

vs.

• Learning with digital maps:- focus on learning subject matter - project based learning- problem solving - community based interaction- authentic assessment

• Example: Ligon Magnet Middle School in Raleigh, North Carolina: Students incorporated digital maps into an oral history project– Formerly a segregated community. Students

interviewed alumni who graduated in the 1930s and 1940s

– Reclaimed historic places on contemporary maps– Used Sanborn fire insurance maps found at municipal

urban planning office– Dr. Marsha Alibrandi

The Sanborn maps vividly illustrated the history of segregation in the community.
