After billions of dollars spent, the impact on student achievement of computer use in K12 has been essentially zero. The reason is: The same textbooks, the same curriculum and the same pedagogy continue to be used, but computers have been substituted for pencil and paper. Teachers have had their students use computers to search for information instead of having them go to their school library. Direct instruction is the technical term for this teacher-centric pedagogical style, but we refer to it as "I teach."

In tough economic times for school districts across the nation, might it help to cut costs further if districts required students to bring their own devices? For now the jury is out, but district leaders are trying to figure out how to support many different devices in their buildings as state and federal funds for education get even tighter than they were just a few years ago.

In 2008 for the first time, laptops outsold desktops. In 2010 for the first time, smartphones outsold laptops.

Mobile learning is on the rise, and consequently, so is the need for mobile connectivity. According to a 2010 survey of E-rate consumers, including public schools and libraries, conducted by the Federal Communications Commission (FCC), 50 percent of respondents said they plan to implement or expand the use of digital textbooks and other wireless devices.

According to a recent study, 43 percent of students feel unprepared to use technology in college and work life. SOURCE: e Education Development Center and Nellie Mae Education Foundation

Everything was hunky-dory. Baby-boomer-age teachers prepared baby-boomer children to take on baby-boomer- age jobs. But things have changed. In the 1990s, the baby-boomer jobs started drying up, and the baby-boomer kids became the digital generation, playing video games and listening to illicit MP3s. And now? Well, it's not hunky-dory at all. Baby-boomer teachers are preparing the mobile generation.

In your schools, In your classrooms, you will soon allow students to use computing devices they already own. While today 99 percent of schools ban cell phones and other mobile devices from the classroom, there will be a 180-degree turnaround within four years. This coming shift is inevitable.

Elliot: It looks like mobile learning is finally at its tipping point.

Cathie: It really depends on one's definition of mobile learning. Schools are buying carts of iPads.

Elliot: I know, it breaks my heart. Haven't we learned anything from the past?

Cathie: A cart of iPads will have about as much impact on student achievement?

Elliot: a cart of laptops had on student achievement. Deja vu all over again!

Cathie: And lest there be any doubt about what we mean...

Mobile learning—the use of mobile devices for educational purposes by students—is rapidly moving from an experimental initiative by a few innovative districts over the last five years to a broadly accepted concept in K12. The latest research and surveys, results of pilot programs, and analysis of trends in both public education and the broader technology industry all indicate that ubiquitous mobile learning—with mobile devices in every student’s hands and used in every classroom, school and district in the country—is advancing quickly and will arrive faster than many expected.
