What began as an effort to provide a service learning component to GIS graduate students at Colorado State University has evolved into a communitywide project incorporating ArcView GIS into K-12 classrooms to improve student achievement in Colorado geography and science standards. The project involves graduate students, professors, GIS users, school district content/technology specialists, and K-12 teachers working in teams to develop standards-based lessons and assessments using ArcView GIS. In addition, students experience real-world GIS applications through the assistance of local users during GIS summer camps and short-term internships. The project may serve as a partnership model for other interested communities.
