Presentation Transcript

  1. My World GIS: A Geographic Information System for Inquiry-Based Learning Daniel C. Edelson Geographic Data in Education (GEODE) Initiative Northwestern University

  2. Motivation • GIS has been recognized for more than a decade as a powerful technology to support inquiry-based learning in • Geosciences • Geography • Social Sciences • As a result…very large investment in • disseminating professional GIS tools to schools • professional development for teachers • curriculum materials development • The result of that…very disappointing implementation rate in classrooms

  3. What is missing? • Attention to the GIS tools themselves… • Professional tools were designed for professionals to be used in professional workplaces • Complexity • Users of GIS tools typically have hundreds of hours of training • Usability • Revenue for GIS developers is in features, not usability. • Technical administration • Difficult to install and maintain in school computing environments

  4. Our solution… • A learner-appropriate and school compatible GIS tool • Power vs. complexity tradeoff • Identifying essential features for education • Usability • heuristic evaluation and user studies • Technical administration • Simple installation, administration, updating

  5. My World GIS™

  6. Data Formats • Points • ESRI shapefile, tab or comma-delimited text files • Polygons and Polylines • ESRI shapefiles • GRIDS • Arcview GRID export, WorldWatcher, netCDF • Images • JPEG with world (TGW) files, geoTIFF

  7. Data Organization • Data files • Local or remote (via local file system, URL, or THREDDS link) • Data library • List of layer names • Index files • Map from layer name to file location • My World automatically creates an index of its data library at launch.

  8. THREDDS Integration • Can currently read grid data from data catalogues via THREDDS • To handle vector data will require data object definitions • Points • Polygons, polylines • To be driven by educational needs, goals, opportunities

  9. My World GIS • My World team: • Principal Investigator: Daniel Edelson • Programmer: Eric Russell • Undergraduate research assistants: Greg Allen, Erin Orawski • Information and free trial download: http://myworld.worldwatcher.org • This work has been supported in part by the National Science Foundation under grants no. 9720687, and 0085946.
