The document summarizes a master's research project exploring the affordances and transformative dimensions of social media in higher education learning contexts. A systematic review of over 150 research studies on social media use in higher education identified three themes - emergent, administrative, and process - which describe how social media is used across formal and informal learning environments. A conceptual model is proposed that positions tools, users, and content as primary interacting actors within digitally connected environments, with fluid roles for users as learners, facilitators, or contributors.
