The document discusses modern approaches to teaching, including behaviorism, cognitivism, constructivism, and connectivism. It describes connectivism as a learning theory based on the premise that knowledge exists within systems and is accessed through participation. Connectivism views learning as creating connections within a network, where knowledge can reside outside of individuals. The principles of connectivism include that learning rests in diverse opinions and connecting information sources, and that the ability to see connections is a core skill. Connectivism learning activities aim for currency of knowledge and see decision-making as part of learning. Examples of media used in connectivism are provided such as social networks, forums, blogs, and portals.
