“Mobile learning, focuses on learning through mobile devices, allowing learners to move about in a classroom or remotely learn from the location of their choice. The movement has gained a lot of steam in recent years, and despite some criticisms, isn’t likely to fade fast – especially as new technologies that make mobile learning more practical continue to emerge and the popularity of remote learning opportunities like online colleges continue to grow.”
Even if you are approaching it from a purely practical perspective, there is so much scope. I’m starting with a small SMS project, after being inspired by the work of Zoraini Wati Abas in the Change 11 MOOC. Read the response to her mobile learning presentation on the Change 11 wiki I’m contributing to.
