This site has multiple ideas for how to keep students engaged with iPads, and as more schools go to 1:1 environments there will only be more ideas.
This video tells about a first grade class that has already begun to use iPads. This could be the way schools go in the future, introducing technology to kids at a very early age. If a class of first graders can handle the responsibility of iPads, then high school students should be more than capable as well. People often do not like to get used to change, so if media devices are implemented at a young age, more kids will most likely be comfortable with them. Even next year at BHS kids who are not comfortable with technology and do not wish to use the iPads for all classes will still have the option of books. People tend to look at change too radically. The new devices do not necessarily mean the way we learn will be completely different.
