Supporting adolescents toward healthy digital media use and digital citizenship more broadly "takes a village" (Hollandsworth et al., 2011). Chapters in this volume have touched on different aspects of digital media use and adolescent mental health, pointing to the importance of clinical intervention. Schools are another crucial entry point for delivery of support and prevention of future mental health difficulties. Educators have considerable reach to a captive audience of youth. Examining why, what, and how they teach students about digital media use and well-being is vital. In this chapter, we review leading K-12 digital media curricula that aim to teach students how to lead healthy digital lives. We outline the content and pedagogical approaches present in these materials and distill a set of learning goals apparent across curricular resources: critical awareness, self-reflection, and behavioral change. Given the relative absence of external evaluations of school-based interventions, we draw on relevant research to suggest both promising directions and key questions for future research.Why do schools take on healthy digital media use and digital citizenship more broadly as a topic of instruction and intervention? At least four distinct drivers are arguably at play: problems, parents, precedent, and policies. First, problems: Digital and social media are meaningful venues for young people's learning and lives beyond the classroom (Ito et al., 2020). As adolescents use apps for peer connection, there are meaningful upsides but also inevitable conflicts. Conflicts that start online routinely spill over into schools, creating problems educators must solve through reactive sanctions, proactive classroom lessons, or both (Hinduja & Patchin, 2011). Other problems that educators feel pressed to solve include in-school device misuse, distraction, and inattention in class due to media-linked sleep deprivation (e.g., Klein, 2020;Sparks, 2013).We are grateful to Chloe Brenner for her exemplary research support and detailed reviews of lesson plans and resources. Thanks also to the program creators and team members who provided us with access to and information about the programs reviewed as part of this chapter. We also acknowledge Anne Collier and Kelly Mendoza for sharing helpful insights about the state of the field of school-based interventions related to healthy digital media use. Finally, we wish to disclose that we are ongoing partners with Common Sense Education, one of the program providers whose curriculum was reviewed as part of this chapter. Both authors have worked closely with Common Sense on research and development related to their Digital Citizenship curriculum.
