Ashlock, JenniferStojnic, MiodragTufekci, ZeynepInformed by evidence that computing attitudes may be uniquely constructed in informal contexts and that the early teens are a key period for academic decision-making, we investigate lines of practice that connect computing skills, attitudes, and videogames. We compare the relationship between computer skill, computer efficacy, and activities associated with gaming using a data set of 3,868 children in middle school. The time that children spend gaming has very modest association with skill and efficacy. Accounting for the frequency with which children modify games, engage in social gaming activities, and the salience of gamer identity explains the gender gap in computer skill and significantly narrows the gender gap in computer efficacy. We find support for the argument that computer skill and efficacy are dependent on children connecting often isolated social contexts, a socially embedded characteristic of the digital divide.en-USgendervideo gamesSTEM educationcomputer sciencedigital technologyArticle
