Rethinking language learning and Web 2.0: from monologism to dialogism and trialogism Françoise Blin, francoise.blin@dcu.ie Web 2.0 applications and immersive environments (e.g. Second Life) are said to offer affordances for the development of new competencies and skills among 21st century learners. In the case of second and foreign language learning, these new environments are increasingly attractive to language teachers and course designers who seek to provide their learners with enhanced opportunities for online production and interaction, both oral and written. Yet, many teachers tend to reproduce, at least initially, their face-to-face practice and fail to engineer language learning activities that realise the unique affordances offered by these new learning spaces (Zheng & Newgarden, 2012). In recent years, researchers seeking to develop new pedagogies for emerging technologies are increasingly questioning the theoretical foundations of current language teaching and learning practices. They call for a rethinking of our conception of language, of its acquisition and of its role in language learners’ cognitive development. Rejecting the “individualistic view of language as code” and pedagogies rooted in the input/output model, which “do not account for the multiple timescales across which learning occurs or the dynamic, distributed, multimodal nature of meaning-making” (Zheng & Newgarden, 2012: 16), they call for the adoption of languaging as an alternative view of language, as well as dialogical and trialogical approaches to language teaching (see for example: Zheng & Newgarden, op.cit,; Linell, 2009; Paavola & Hakkarainen, 2005). This presentation proposes that Cultural Historical Activity Theory (CHAT) and Engeström’s theory of expansive learning (Engeström & Sannino, 2010) can help us design and implement language learning tasks that exploit the affordances that these environments offer. Following an overview of concepts that have been brought in recent years to the fore of Applied Linguistics debates, such as languaging, emergence, competence, and agency, it proposes and discusses a five-step design model, rooted in CHAT, which can be applied in a variety of contexts for a variety of task types with a view to enable language learners to participate in knowledge creation activities and to become agents within their language learning environment. Examples drawn from French modules currently delivered in DCU illustrate how the model can be applied to real language learning situations. References Engeström, Y. et Sannino, A. (2010).
