This chapter discusses the potential of social software and Web 2.0 tools to enhance language learning in a blended learning context. It describes an English as a Foreign Language course that introduces students to several Web 2.0 tools with the aim of helping them develop their own Personal Learning Environment. As students become familiar with the almost endless opportunities for accessing and participating in authentic language on the Web today, they must also learn to find appropriate resources, filter unsuitable materials, manage this information overload, and decide which tools best suit their own learning style. The chapter argues that accompanied with the right pedagogical approach, these tools enhance learning by allowing students to engage in self-directed learning and gain skills and resources that are transferable to their informal, lifelong language learning.
