She presents 16 case studies from language arts, social sciences, math, and science classrooms in the US and other countries that describe how and why teachers use cell phones, problems they encountered, policies, rules, lesson plans, student and parent reactions, and reflections on results, then details uses for school administration. Sample lesson plans and tutorials, tips on getting started, discussion of policies and appropriate use, and research findings are included along with a list of applicable Web 2.0 tools.
