= GPS: Global Positioning System = = = GPS devices assist the user in finding various locations. They can provide the user with exact latitude and longitude coordinates - down to decimal degree notation - of one's current location or other specified locations. GPS devices can also provide directions as well as information regarding nearby resources and points of interest.

Teachers may use GPS devices in the classroom in several ways. GPS devices can help clarify for students the concepts of latitude and longitude. Students can determine the coordinates for specific locations or can determine the specific locations for given coordinates. GPS devices can also assist students in map reading and direction. Teachers can make a GPS scavenger hunt (popularly called geocaching) on the school grounds in which students will need to use the device and appropriate coordinates to locate items. Moreover, as each student is unlikely to have a GPS device, the teamwork would also provide a form of cooperative learning with all of its benefits.
