Project TELL supports learning teams made up of teachers and community members to develop instructional units that improve student learning through the effective use of technology. These units will also ensure that students learn the technology skill needed to become productive workers in the 21st century including: database programs, graphing, statistics and geographic information system technology. Geographic Information System Technology (GIS) is an integrated system of computer hardware and software which support analysis and modeling of spatially referenced data. GIS has the potential to become an important K-12 educational tool. Pilot projects have begun with local teachers who use GIS to describe, compare and explain patterns found in ecosystems, resources, and human adaptations. Over the next five years we hope to develop K-12 computer units to teach grade level benchmarks.
