Book excerpt: ICT and globalization have completely redefined learning and communication. People virtually connect to, collaborate with, and learn from other individuals. Because educational technology has matured considerably since its inception, there are still many issues in the design of learner-centered environments. The Handbook of Research on Ecosystem-Based Theoretical Models of Learning and Communication is an essential reference source that discusses learning and communication ecosystems and the strategic role of trust at different levels of the information and knowledge society. Featuring research on topics such as global society, life-long learning, and nanotechnology, this book is ideally designed for educators, instructional designers, principals, administrators, professionals, researchers, and students.
