THE WORLD IN YOUR POCKET: Smartphone adoption and Internet access among American teens is "pervasive," according to the latest Pew survey of 802 teens (ages 12 to 17) and their parents. Thirty-seven percent have smartphones (up from 23% in 2011) and 23% now wield tablets. Twenty-five percent are "cell-mostly" Internet users, a number that jumps up 50% among those with smartphones. These trends appear to be holding up in students' study habits as well: StudyBlue CEO Becky Splitt shared at SXSWedu that average user session times for its popular mobile flashcards and study guides were highest for tablets (twenty minutes, fifty-five seconds), as compared to smartphones (17:55) and laptops (15:50).
