Abstract
Students learn Geographical concepts more effectively if they can identify and generalize about where different resources or activities are spatially located and when they associate certain patterns and processes with geographical changes. Digital libraries can be used to support web-based student-centred inquiry as a mode of learning Geography. This study explores the affordances of a geographical digital repository (the G-Portal) which organizes information around problem tasks. Two phases of the project were to build a digital library for Geographical assets and to develop a place-name assignment algorithm which automatically determines the names of places embedded in web pages referenced by these assets so as to augment them with the appropriate location semantics. This G-Portal digital library serves an active role in collaborative learning activities in which students conduct a virtual field study of an environmental problem, within a geospatial context – in this case, beach erosion and sea level rise. GPortal also provides manipulation and analytical tools that can operate on the information retrieved.
