Historic barriers to wide-spread use of GIS in the classroom are being lifted as educators embrace the power of Web-based GIS and other Internet based geospatial technologies. Two NSF-funded projects at Lane Community College in Eugene, Oregon - MAPS-GIS (Mapping Analyzing and Problem Solving with GIS) for college level students and GEOSTAC (Geospatial Teaching Across the Curriculum) for high school teachers – will be discussed. We will illustrate how Web-based GIS is being embedded across the curriculum and how it is being used to teach important geospatial concepts and skills and educate students about GIS classes and careers.
