Below is an interview by Russell Southwood of Balancing Act Africa on mobile learning in Africa. The interview has two parts: the first video is about how mobile learning can tackle the global teacher shortage and the impact of mobile learning on the education system.
The second part is about the power of interactive and “edutaining” content via mobile devices, for example through the Yoza Cellphone Stories project.

Hi – it all looks like global convergence of ideas – one of my MEd students at Victoria Uni. (Australia) wrote a paper some years ago about use of mobile phone/camera systems as teaching aid in post-secondary apprentice training. We then speculated on creating an advanced iPhone that forward-projected a keypad onto the table & a rear-projector to a screen (a piece of A3 blank paper even).
The biggest problem are questions of language & scripts – we must avoid imposition of new linguistic imperialisms (English Arabic etc) – we are all too aware of the methods of anglicization of Eire, or attempted Russification of the Baltic Republics.
