Some recent material to explore in deeper depth over the next few weeks pertinent to each approach, and to add to existing literature include the following.
mobile learing - The Joint Committee for Information Systems (JISC) have put out the recent wiki document covering an overview of mobile learning, strategies, pedagogy, technical considerations and case studies. A sort of one-stop shop to find out about what is mobile learning and how to implement into educational settings.
Also of interest is mobile usage and Derek's blog provides a cartoon to bring together data on how American's are always connected via their mobile devices.
Constructivism - George Siemen’s work on connectivism has been introduced as a concept that updates constructivism into the information era. A recent presentation (on sensemaking and wayfinding)provides a summary of some of his recent thinking including how connectivism builds on and extends traditional teaching/learning approaches into the digital era (slide 10).
