The document discusses the importance of learning sciences and technology-enhanced learning. It notes that society has shifted to a knowledge economy, requiring lifelong learning. Learning sciences study teaching and learning through various fields like cognitive science. Standard schooling models are based on assumptions not backed by science. Learning sciences emphasize deeper conceptual understanding over facts, connected knowledge over isolated bits, and collaborative learning over individual work. Technology can support deep learning by representing knowledge concretely and allowing sharing. Collaborative learning stimulates knowledge acquisition mechanisms but requires productive group interactions. Computer-supported collaborative learning occurs in complex social and technological environments and is an approach to developing self-regulated learning opportunities and competence tools. Media alone does little for learning; students' activities are critical
