Technology sometimes offers novel ways to study old topics. GPS devices are becoming more common and are even embedded in devices such as iPhones and Nokia N95 phones; the cheaper handheld GPS devices can be obtained for less than £100.
Taking one of these devices on a walk can offer a numberof learning opportunities. More advanced devices will display location and tracks on a map so that students can see exactly where they are and reconcile it with features that they can see. This information can be used to draw tracks on the ground – they can show thei knowledge of 2D shapes by walking in patterns, recording waypoints at each vertex.
Back at base, these tracks and waypoints can be embedded in a Google Earth kml file and printed out to make an interesting wall display; perhaps they could be put in a place on the web where students can show them off to parents.
