Last year, kindergarten through high school students in the rural Hector, Arkansas, School District barely had the technology resources that keep kids interested in math and science. This year, they potentially have the most advanced resources in the country--before they even step into the classroom. One school bus in Arkansas' Pope County has been transformed into a mobile classroom equipped with computer screens mounted to the ceiling, earphone jacks, wireless Internet access, and a scanning device to record bus activity. "Mobile classroom" streams math and science content that students can watch on hour-long rides.
