Speech acts are an important and integral part of day-to-day life in all languages. In language acquisition, the need to teach speech acts in a target language has been demonstrated in studies conducted in the field of interlanguage pragmatics which indicate that the performance of speech acts may differ considerably from culture to culture, thus creating communication difficulties in cross-cultural encounters. Considering these concerns, the aim of this volume is two-fold: to deal with those theoretical approaches that inform the process of learning speech acts in particular contextual and cultural settings; and, secondly, to present a variety of methodological proposals, grounded on research-based ideas, for the teaching of the major speech acts in second/foreign language classrooms. This volume is a valuable theoretical and practical resource not only for researchers, teachers and students interested in speech act learning/teaching but also for textbook writers wishing to have an informed opinion on the pedagogical implications derived from research on speech act performance.
