Chen, X. B. (2013).
The pervasive use of mobile technology not only brings great convenience to people's life, but also changes the way people study． Nowadays, it is quite common for students to utilize smart phones, tablet computers, portable multimedia players and other mobile devices to learn a foreign language, These tools provide them with convenient access to learning materials, while at the same time eliminated the time and space limits of foreign language learning, making up for the lack of interactivity, collaboration, and real context contact of the traditional foreign language classroom. The present paper attempts to define mobile assisted language learning, look at the features of this new learning mode, and discuss the advantages and challenges of it with regard to the traditional language learning mode. It is concluded that before foreign language teachers adopt these mobile technologies in their language teaching practice, the technological affordances of different mobile devices need to be fully considered, so as to be able to design language activities that are in line with language acquisition and cognitive laws. Only by doing this can language teachers effectively guide their students to utilize mobile technologies for language learning．
