In these changing times of global flows of media and technologies and reports of declining reading enjoyment, researchers, policymakers and educators need to engage anew with essential issues of what counts as reading, what kinds of reading matter and how to support teen reading engagement in school and out-of-school settings. Bringing together contributions from well-known and emerging adolescent literacy researchers from different disciplinary perspectives, this edited collection consolidates contemporary research on teens’ volitional print and digital reading, whether in school or out-of-school contexts. The first part of the book offers overviews of what teens are reading, followed by chapters on community support on reading and new ways of researching teen reading. With chapters from North America, Europe, Australia, Asia and the Middle East, the collection will offer multifaceted and complex insights into what, how and why teens read in different contexts. Reflection questions at the end of each chapter encourage readers to consider how the research can be applied in their own research, policy and practice contexts. This book will be of interest to researchers, policymakers and educators who are invested in supporting adolescent-engaged reading with evidence- based policies and strategies.
