Developed from presentations at the Fifteenth International Writing Across the Curriculum Conference, this edited collection celebrates the 50th anniversary of the WAC movement while also identifying innovative directions for writing pedagogies, program building and impact, and program mobilization. Contributors reflect on the evolution of WAC as an educational movement as well as the challenges and possibilities facing WAC programs as they respond to the shifting contexts of higher education. The chapters in this collection-found in sections on faculty development, classroom implications, and institutional considerations-offer a range of practices, pedagogies, frameworks, and models for readers who are invested in building and sustaining WAC programs that impact their college and university campuses through cultures of writing. Adapting the Past to Reimagine Possible Futures engages topics such as program assessment, professionalization, and interdisciplinary collaborations, and connections with creative writing. Its 17 chapters testify to WAC's persistence, resilience, and impact in a dynamic educational landscape.
