Introduces the research and science of learning, integrating theory with case studies about learning principles and high-impact practices. Learning takes place in all stages of life: teenagers who go directly from high school to college, adults who “stop out” and return to school after years of work or family commitments, and even retirees who pursue learning made possible by expanded leisure time. Some education takes place formally within higher education; other opportunities are informal, sponsored by organizations such as museums and libraries or available for free online. Focuses on learning in online and mobile environments.
