Dr. James Stanfield's lecture explores theories of learning, focusing on constructivism and connectivism. Constructivism emphasizes that individuals build their understanding through social interactions and experiences, particularly illustrated by Vygotsky's ideas on development and the role of teachers in facilitating learning. Connectivism, developed by George Siemens, highlights the importance of networks and technology in learning, suggesting that knowledge is dynamic and interconnected rather than merely retained information.
