The study investigated how retired older adults (age 55+) use the Internet and social media to facilitate informal, self-directed learning, specifically, exploring how they use mobile devices (smartphones, tablets) to enhance, access and maintain their online personal learning networks (oPLNs), facilitating "on-the-go" learning. Following a mixed methods approach, Phase I of this two-phase research project implemented a 52 question online survey distributed to 385 (n = 218 males, n = 165 females) retired older adults (age 55+) from across Canada. Results indicated 634% use mobile devices to access the Internet outside the home, 589% use a mobile device to specifically communicate with their oPLNs, and 468% use apps to support their mobile learning. Implications for the use of mobile devices to empower older adults' personalized learning opportunities is discussed.
