Applications for Education
As I mentioned on Monday, Tour Builder could prove to be a great tool for students to use to create geo-located book reviews, to tell stories from their own lives, or to develop geo-located research projects. One of the US History projects that I've done with Google Earth is to have students create a series of placemarks about battles of the Revolutionary and Civil Wars.
