As the field of mobile learning has developed and devices have advanced, there have been a number of ephemeral definitions of mobile learning. Earlier definitions have named a particular device which quickly becomes dated, or they have been techno-centric. For example, in 2005, Traxler defined mobile learning as ‘‘any educational provision where the sole or dominant technologies are handheld or palmtop devices.’’ In the past decade, technologies have evolved beyond just handheld or palmtop devices. Nonetheless, trends have emerged from these definitions that highlight the four central constructs of mobile learning as pedagogy, technological devices, context, and social interactions (Crompton 2013a). Aligned to these constructs, Sharples et al. (2007) tentatively defined mobile learning as ‘‘the processes of coming to know through conversations across multiple contexts among people and personal interactive technologies’’ (p. 224). This is the definition selected for this article.
