In this fourth and final report, Power in Numbers presents insights from its three foundational reports, accompanied by case studies that illustrate how organizations have implemented best practices in the real world. The case studies — featuring diverse adult education stakeholders, approaches, and lessons learned — demonstrate that there is not a single prescriptive path to supporting successful adult learning. Through these case studies you will learn: How a state-wide OER initiative has saved an estimated $55 million in textbook costs for its university students. How an investment fund has supported the scaling of seven adult workforce technology companies. How professors at a community college piloted an innovative distance learning model that has improved minority students’ course performance.
