Neat idea. And predictable, yet still fascinating results.

[O]n this chilly morning, as bus No. 92 rolls down a mountain highway just before dawn, high school students are quiet, typing on laptops.

Morning routines have been like this since the fall, when school officials mounted a mobile Internet router to bus No. 92’s sheet-metal frame, enabling students to surf the Web. The students call it the Internet Bus, and what began as a high-tech experiment has had an old-fashioned — and unexpected — result. Wi-Fi access has transformed what was often a boisterous bus ride into a rolling study hall, and behavioral problems have virtually disappeared.

“It’s made a big difference,” said J. J. Johnson, the bus’s driver. “Boys aren’t hitting each other, girls are busy, and there’s not so much jumping around.”
