This chapter characterizes the way in which social presence technologies mediate digital identity, presence learning, and Presence Pedagogy (P2) in the context of higher education. It is argued that digital identity, presence learning, and P2 manifest themselves through the four social presence technologies in varying degrees. Against this backdrop, the chapter first provides a concise overview of digital identity, social presence, presence learning, and P2. Second, it presents seven projects to demonstrate how digital identity, presence learning, and P2 are mediated by these four social presence technologies. Third, the chapter outlines future trends likely to influence social presence technologies, digital identities, presence learning, and P2.
