This book is written in order to help undergraduate students and trainee teachers to reflect on certain topics and key issues related to second language acquisition. Despite the proliferation of books and introductory courses in second language acquisition, most of these books very often provide a very complex account of theoretical views in second language acquisition and sometimes fail to emphasise the crucial interplay between how people learn languages and what is the most effective way to teach languages.
The overall purpose of this book is to provide an overview of second language acquisition research and theories by identifying the main key issues in this field and by highlighting the relevance of this research for classroom implications. The study of second language acquisition is a rich and varied enterprise, carried out by researchers, whose interests and training often lie in broader disciplines of linguistics, psychology, sociology, and education.
Readers will be encouraged to critically reflect on the presented content through self-engaging thinking activities in the form of questions, matching activities, choices and conclusions about the implications of SLA theories to the real world applications.

Alessandro G. Benati is Professor in the School of Education, University College Dublin, Ireland. He has held positions in several British and overseas institutions. He is known for his work in second language acquisition, and he published ground-breaking research on the pedagogical framework called processing instruction. His research on processing instruction has been recently driven by the use of new online measurements (e.g., eye tracking, and self-paced reading). Alessandro has coordinated national and international high-impact research projects which have been influential in determining educational policy and had an impact in providing effective language teacher training programs. He is the author and co-author of several research monographs, peer-reviewed articles in high-ranked journals, and editor and co-editor of book series and scientific journals such as Cambridge Elements in SLA and Instructed Second Language Acquisition. He was a member of the sub-panel for Modern Languages and Linguistics for the Research Excellence Framework for England (REF 2021), AHRC Panel, and he is an Honorary Professor at Your SJ University (UK), University of Hong Kong (China), Adjunct Professor at Macquarie University (Australia), and Visiting Professor at Anaheim University (USA)
