One morning last winter I watched a middle-school teacher named Al Doyle give a lesson, though not your typical lesson. This was New York City, a noncharter public school in an old building on a nondescript street near Gramercy Park, inside an ordinary room that looked a lot like all the other rooms around it, with fluorescent lights and linoleum floors and steam-driven radiators that hissed and clanked endlessly.
Doyle was, at 54, a veteran teacher and had logged 32 years in schools all over Manhattan, where he primarily taught art and computer graphics. In the school, which was called Quest to Learn, he was teaching a class, Sports for the Mind, which every student attended three times a week. It was described in a jargony flourish on the school’s Web site as “a primary space of practice attuned to new media literacies, which are multimodal and multicultural, operating as they do within specific contexts for specific purposes.” What it was, really, was a class in technology and game design.
