This chapter will describe the notion of Mobile 2.0, which essentially, is Web 2.0 on mobile handsets, and the implications for language learning. It will provide definitions, current developments in Mobile 2.0, and how Mobile 2.0 applies to language learning. The final section of the chapter will focus on the future and implications of Mobile 3.0.

The structure of the chapter is as follows: following an introduction to the field, the background of the existing research on Mobile 2.0 is outlined, and a definition of Mobile 2.0, and its relationship to Web 2.0 is provided. The next section discusses several Mobile 2.0 phenomena that have recently been seen in the realm of business, and their possible applications to the field of language learning. Some examples of existing Mobile 2.0 sites will then be outlined, and ideas for using these mobile phone oriented sites for language learning purposes are given. Next, the chapter discusses some of the technical details for constructing one’s own Mobile 2.0 sites for teaching, while considering the economics of creating them. This leads to a discussion of exactly how Mobile 2.0 brings about a new trend in mLearning and provides an explanation of how a transformation in mLearning will occur. Finally, some drawbacks of Mobile 2.0 technologies for learning purposes will be delineated.

This chapter introduces the concept of Mobile 2.0, a mobile version of Web 2.0, and its application to language learning. The chapter addresses the following questions: What is Mobile 2.0? How is it relevant to the concept of Web 2.0? Is Mobile 2.0 ready for language learning analogous to that of Web 2.0? How is the efficacy of m-learning using Mobile 2.0 technology compared to PC Web 2.0? If Mobile 2.0 is appropriate for language learning, then how does one go about setting up a Mobile 2.0 site? Is Mobile 2.0 leading to a transformation of mLearning? Are there any limitations in using Mobile 2.0 for language learning? Finally, is Mobile 3.0 already emerging for learning? These issues will be discussed, and the relevant data will be presented to support the claims made in this chapter. Furthermore, specific examples of Mobile 2.0 and the empirical data of specific uses of mobile phones for educational purposes, especially for language learning in Japan, will be delineated. This chapter suggests that knowledge of Mobile 2.0 will strengthen and reinforce language teaching and allow students to learn more ubiquitously, more effectively, and in a way that is more at ease with their learning styles.
