A new 414-page book has been released or free download. The book entitled "Innovative Mobile Learning: Techniques and Technologies" is a collection of chapters from across the world, edited by Hokyoung Ryu and David Parsons from Massey University, New Zealan.
"The aim of Innovative Mobile Learning: Techniques and Technologies is to introduce the reader to the current directions of mobile learning (a.k.a., m-learning). More precisely, it is about providing a comprehensive survey of mobile learning research and projects that both academics and educational practitioners may utilize in their work."
