Kids' use of games, cellphones, and smartphones (next-generation, Web-browsing, media-sharing phones), "if carefully managed, could significantly boost their learning," Education Week reports, citing a just-released, 52-page study by a research center based at the Sesame Workshop (formerly Sesame Street) in New York. "Mobile devices are part of the fabric of children's lives today: They are here to stay,” said Michael H. Levine, executive director of the Joan Ganz Cooney Center, in a statement about the report. "It is no longer a question of whether we should use these devices to support learning, but how and when to use them." Among the report's recommendations are "investments in research and development aimed at understanding the impact of mobile technologies on children’s learning and development, including brain and behavioral functioning" and "a digital teacher corps that would train other teachers and after-school caregivers to use digital media to promote 21st-century literacy." Here's the Joan Ganz Cooney Center's blog, with links to the executive summary and full report in pdf format.
