This document discusses an OECD project on innovative learning environments. It aims to promote deep learning, 21st century competencies, and lifelong learning through innovation. The project focuses on understanding learning from research, conceptualizing innovative learning environments through case studies, and supporting implementation and change. Key aspects of innovative learning environments are that they make learning central, are social and collaborative, are attuned to learner motivations and emotions, accommodate individual differences, are demanding but not overloaded, use formative assessment, and promote connections across activities.
