While mobile electronic devices are often viewed as a classroom nuisance, some teachers have found practical ways they can be used as teaching aids. Learning In Hand, a free how-to site, shows teachers the many practical instructional uses for a cellphone or MP3 player. By downloading a software application or podcast, a smartphone quickly turns into a learning tool for math or science teachers. The site demonstrates a number of ways to bring technology into the classroom, and its up-to-date blog keeps readers posted on educational developments in mobile technology.
