This document discusses the evolution of teaching and learning infrastructure from traditional learning management systems (LMS) to more open and connected models. It notes limitations of the LMS model in being primarily transactional and administrative rather than focused on learning. It advocates for more flexible, modular systems that are less centralized and allow richer connections between learning applications and resources. The future of learning infrastructure is seen as more open, participatory ecosystems in the cloud rather than closed, course-centric LMS platforms.
