Built on the foundation of four years of research and implementation of mobile learning projects (m-learning), this paper provides an overview of the potential of the integration of mobile Web 2.0 tools (based around smartphones) to facilitate social constructivist pedagogies and engage students in tertiary education. Pedagogical affordances of mobile Web 2.0 tools are evaluated, and student usage and feedback is outlined via an interactive multimedia timeline (using "YouTube" videos) illustrating how these mobile Web 2.0 pedagogical affordances have transformed pedagogy and facilitated student engagement in a variety of course contexts. A rubric for evaluating appropriate smartphone choices is provided, and a model for implementing mobile Web 2.0 pedagogical integration is presented. (Contains 1 figure and 4 tables.)
