Data usability aspects in children’s geospatial learning

  1. 1. Data Usability Aspects in Children’s Geospatial Learning Johannes Schlüter, 23. 03. 2010
  2. 2. GeospatialLearning@PrimarySchool Motivation: • GI science and geographic information in general public • MIT One Laptop Per Child “It’s an education project, not a laptop project” - Nicholas Negroponte Johannes Schlüter, 23. 03. 2010
  3. 3. GeospatialLearning@PrimarySchool • Application for the XO-Laptop to foster – Spatial Thinking – Spatial Orientation – and to improve the geography classes • Framework with plugins – Geocaching – Geotagging Johannes Schlüter, 23. 03. 2010
  4. 4. Geocaching with the XO-Laptop Johannes Schlüter, 23. 03. 2010
  5. 5. Challenge for the software – limited attention span of the children – limited experience with computers, especially laptops – no experience with geospatial applications – it should not be necessary to know GI concepts in order to use the application – cross-cultural use without specific localization of texts, symbols – restrictive design rules of the XO make it difficult to design a proper interaction Johannes Schlüter, 23. 03. 2010
  6. 6. GI usability aspects • Player position – symbology – data accuracy (GPS, continious) • Treasure position – symbology – data accuracy (GPS, acquired once) • Base map (OSM) – symbology (predefined symboles) – data quality (VGI) Johannes Schlüter, 23. 03. 2010
  7. 7. Test Results • most children had prior experience with GI • Level of detail • OSM data do not provide enough detail • symbology wasn`t always self-explanatory • children had orientation problems they assumed the north on the map is straight ahead • all children had fun!!!
