This document discusses the history and development of mobile learning (m-learning) from its early beginnings to its current and future states. It traces the evolution from traditional classroom learning through e-learning to today's m-learning, enabled by ubiquitous personal mobile devices. Key points discussed include the driving forces behind m-learning adoption, examples of current m-learning applications and platforms, and the potential for m-learning to support both formal education and informal, on-the-job training in the future. Diagrams are presented outlining trends in learning styles and potential uses of m-learning within enterprises for tasks like workforce training, field service operations, and knowledge sharing.
