AUSTIN, Texas — Technology is everywhere at KIPP Austin Obras, a charter elementary school in Texas. One day at the beginning of the school year, first-graders grappled with math concepts as they tried to coax JiJi the penguin across the screen of their netbooks. Kindergarteners in a Spanish-language technology class learned to log on to their computers while second-graders did elementary coding on a Flappy Bird game, with one boy turning the birds into tiny Santa Clauses.
