Most conventional educational activities are time and space dependent. With the emergence of the correspondence education, a new era of education started that was not entirely dependent on time and space requirements. Education in the form of printed materials reached the learners wherever they are, rather than learners coming to the classrooms. These learners were mobile (changed places due to job mobility and other situations), and used the learning materials anytime, anywhere. But, it was never called mobile learning! However, with the increased use of mobile phones and Personal Digital Assistants (PDAs), and the demands for just-in-time education, a new genre of teaching-learning emerged in the form of 'Mobile Learning.' With the rapid growth in the number of users of mobile devices around the world, it is touted as the new found panacea for education in the less developed world. The book under review is a testimony to the current interests in the use of mobile technologies in education. Agnes Kukulska-Hulme and John Traxler bring together a group of researchers to report their indulgence with mobile technologies and education. The book includes 12 case studies and eight general chapters on mobile learning, besides an exhaustive glossary on the topic at the end.
