Where does enduring individual interest come from? One answer is, through social experience that derives from a need for belongingness. Because of this need, students seek social links that influence the development of individual interest. This may occur through experiences with parents, friends, passionate affinity groups, competition, public performance, and culture. School is a social experience that can influence interest development. School-prompted interest and transformative experience should be goals of schooling, yet research suggests that they occur at a lower-than-optimal rate. Research on interest could expand its methods to include techniques such as social network analysis, cell phone data collection, and day reconstruction. Research should attend to the fact that the manifestation of interest is more dynamic and complex than sometimes represented, and real-time experience and remembered experience can be quite different.
