Few academic issues are of greater concern to teachers, parents, and school administrators than the academic motivation of the adolescents in their care. There are good reasons for this concern. Students who are academically motivated perform better in school, value their schooling, are future-oriented in their academic pursuits, and possess the academic confidence and positive feelings of self-worth so necessary to increasing academic achievement. Because academically motivated students engage their schoolwork with confidence and interest, they are less likely to drop out of school, suffer fewer disciplinary problems, and prove resilient in the face of setbacks and obstacles. It is precisely because academic motivation is so essential to academic achievement that motivation has taken a place along with cognition as one of the most followed lines of inquiry in educational psychology. In this volume, we are fortunate to gather together some of the most eminent scholars who have written extensively about the academic motivation of adolescents. We are fortunate also in that they represent the varied theories and lines of inquiry that currently dominate research in this area. In all, we believe that in the dozen chapters that comprise this volume, the authors provide elegant insights regarding the academic and social motivation of adolescents that will prove of interest to researchers, students, teachers, school administrators, parents, policymakers, and all others who play a pivotal role or are otherwise invested in the lives of adolescents in today's society. It is our hope that these insights will not only further the conversation on adolescence and education, but will serve as the impetus for further research capable of generating the creative ideas, programs, and structures so necessary to better the lives of the young people in our care.
