A phenomenon attracting increasing attention in language curricula is the infusion of technology into traditional, face-to-face (FTF) language instruction. Nevertheless, computer-assisted language learning (CALL) still lacks a body of qualitative research on the notion of blended learning (BL). Particularly, what is lacking is information regarding teachers' perceptions of blended learning, or the roles they are expected to play in such mixed environments; without an understanding of these issues, the creation of new and effective BL curricula is extremely difficult (Grgurovic,2010). That said, much research has been conducted comparing learning outcomes in traditional and blended foreign language classes, although the various socio-cultural (external) and psychological (internal) aspects governing the successful transition of both teachers and learners from FTF to online learning remain unexamined (White,2006). This literature review consequently focuses on the infusion of technology into the language curriculum, specifically in relation to BL, with three purposes in mind: to a) exemplify teacher perspectives on BL; b) their effective transition from FTF to technologicallyenhanced instruction; and c) examine those factors which are identified as the reasons for teachers having effectively implemented the technological components into a blended curriculum.Keywords: Blended learning; hybrid courses; educational technology.
Introduction.As societies change in response to challenges in the social, political and economic arenas, so do their education systems (Kelly, 2009 (Smith & O'Day, 1990, in Means, 2008 This embracing of technology within language teaching has fostered numerous teaching and learning practices. As far as tertiary education, in which I teach, is concerned, great strides have been made in investigating the possibilities of BL. The main reasons for this are the need to: be flexible in delivering education; address the challenges of geographic distance, and; deliver higher education on a global scale (Bach, Haynes and Smith, 2006). Consequently, BL, the model that integrates online with traditional FTF learning, has become a favored strategy of many English preparatory university programs in attempting to meet the requirements of language learners, institutions, and local and national educational authorities.Despite the wealth of research illustrating the multifarious difficulties of implementing technology-mediated innovation, systematic analysis of the roles, perceptions and practices of language teachers in BL models is lacking.
