The Common Core State Standards call for students to develop digital media and technology skills. One way to help them reach that goal: incorporate gadgets they're already familiar with--cell phones, tablets, and smartphones--into their learning environment. Mobile devices are becoming essential to students' daily lives. According to a 2011 Pew Internet Project teen survey, 77 percent of 12- to 17-year-olds have cell phones, a major jump from 45 percent in 2004. And yet, many schools do not allow cell phones and the like. New York City schools, for example, have prohibited students from bringing cell phones, or electronic devices in general, to class. This paper discusses the pros and cons of mobile devices for learning; presents a rundown of available devices and how they have been deployed in classrooms; provides resources and tools that support mobile learning; shares ideas for elementary, middle, and high school classrooms; and describes how to get parents on board the mobile device train. A list of resources is included. [Funding for this paper was provided by Google.]
