Eva Fernandez and I have created this blog to generate a lively discussion of fossilization in adult second language acqusition. We hope that language teachers, second language acquisition researchers, and applied linguists will discuss the importance of linking L2 acquisition theory to pedagogical practice, share intervention techniques that can potentially increase the chances for adult learners to acquire native-like proficiency in their target language, and offer guidance for language practitioners to incorporate such techniques into their own teaching.
