The challenge to improve second language acquisition efficiency has always been at the heart of education because a good command of a language provides new opportunities to manipulate information and apply acquired knowledge and skills to novel problems in new situations. Thus, there is a necessity for creating an alternative to either task-based or form-focused methods commonly employed in today’s instruction. An Invariant-Based Approach to Second Language Acquisition: Emerging Research and Opportunities is an essential reference source that elaborates on traditional 2L concepts and terms and provides new practical tools and mechanisms for developing student communicative competencies. Featuring research on topics such as syllabus design, language interpretation, and speech types, this book is ideally designed for educators, administrators, researchers, and academicians.
