A growing number of students with special needs are using iPads in the classroom this year. The lightweight, mobile devices can be customized for students with disabilities and help give them a sense of inclusion with their peers. "I think the key word for this is engagement," said David Barry, the superintendent of a Michigan school district. "The engagement was just a lot higher. I think it's adaptive to meet the needs of individual students. I think it's an equalizer. I do think it's a game changer."
