This document discusses the concept of smartness in learning ecosystems. It defines key principles of digital learning ecosystems, including openness, interconnected components, and feedback loops. It examines how learning ecosystems can be autonomous, energy-efficient, responsive, able to sense signals, have networking capabilities, use data to make predictions, and actuate changes. The document presents research analyzing factors that determine different types of digital learning ecosystems in schools, from basic ICT use to more advanced ecosystems with learning and networking flows. It concludes that measuring learning ecosystem smartness involves evaluating autonomy, responsiveness, and productivity over time as ecosystems become more responsive and better able to adapt to future changes.
