As the first part of a new “Key Concepts of Online Learning” series, Contact North explores the meaning of mobile learning, which they define as “the use of broadband connected devices – smart phones, tablet devices, e-readers, and laptop computers – so that students can connect to learning opportunities either synchronously or asynchronously from anywhere in the world. The mobility has two dimensions – the students are not restricted to a classroom or any other physical location, and the devices are easily portable and usable for communication and collaboration, as well as information delivery.”
