"The insights and arguments in this book emerged primarily from a large, mixed-methods study of tweens' and teens' perspectives on digital life that we carried out between 2017 and 2021. We launched this study, the Digital Dilemmas Project, with the aim of understanding young people's perceptions of the upsides and challenges of the digital landscape at that time. We also wanted to understand the ways adults were supporting them, and implications for new or revised supports. Our broad questions were: How are young people navigating thorny digital issues and dilemmas that surface in networked life? How are adults supporting them? What more could adults do? Our inquiry included digital issues and dilemmas that spanned four spheres: personal well-being, close relationships and intimacy, peers and community, and the broader civic or public sphere. When we set out to do this research, we envisioned our findings being mainly directed toward new or improved educational materials. Our home base is at Project Zero, a research center at the Harvard Graduate School of Education. Our longstanding partnership with Common Sense Media was key. Carrie first collaborated with Common Sense Media in 2006 to support development of their research-based Digital Literacy and Citizenship curriculum. Over fifteen years later, Common Sense Media is a leader in providing digital educational resources to schools in the United States and, increasingly, around the world. In 2017, we partnered with Common Sense Media once again this time, to bring fresh insights from empirical research to support updates to their curriculum. As we collected our data, we saw immediate implications for the content of curricular lessons and pedagogical approaches. These insights were leveraged in short order to develop and pilot test new materials for schools. But we also came to see that our data had relevance beyond schools. The more we began to share selected insights from our survey, the more we realized that what we were learning had relevance for a broader audience, including parents, mental health professionals, youth development organizations, and technology companies. This book is one outcome of a quest to bring this research to a larger public stage. Throughout the book, we've referred to our surveys, interviews, classroom observations, and youth advisory council sessions. Further details follow about these studies and our research participants. Because we have worked on these topics for over a decade, we've also had a steady stream of opportunities to have less formal discussions with teens, parents, and professionals who work with youth. These discussions often surface stories that corroborate themes in our more formal studies. They also showcase tensions through real-world dilemmas." (Appendix, pages 179-180)
