Every day is Bring Your Own Technology day at some schools, reports Mind/Shift. In Mankato, Minnesota, students are encouraged to bring netbooks, laptops, and tablets that connect to the school’s wireless network.

“By allowing kids to bring in their own devices, you free up school resources for the kids who don’t have access,” says Doug Johnson, director of media and technology for the Mankato Public School System. (Johnson wrote the book — literally — on the subject; The Classroom Teacher’s Technology Survival Guide is published this month.) For example, in classrooms that have a group of four computers, finding time for all 30 students to use them can be challenging.

Some 90 percent of Mankato students have a wireless-capable device.  Not all schools could count on most students bringing their own technology, though smart phones are spreading rapidly.
