This chapter first situates our field with reference to discussions around the numerous “turns” in applied linguistics and SLA, e.g., social, multilingual, decolonial and racial. While the time seems ripe for transdisciplinary SLA pursuits because of facilitative conditions created by the open science and the slow science movements, for instance, there are also obstacles including the neoliberal management structure in academia which can challenge such undertakings. The chapter provides some pointers for how transdisciplinary research can be conducted. Reflecting on transdisciplinarity can stimulate the rethinking of a monolithic conceptualization of language, the reexamination of the monolingual basis against which development and success are measured and the interrogation of the nature of multilingual competence. Moreover, working transdisciplinarily can potentially help better serve the users we need to serve and mitigate against the misapplication or misinterpretation of our findings. Importantly, as a field that sits on and benefits from intersections (e.g., between languages, cultures, experiences), the chapter argues that SLA researchers have a moral and ethical duty to try to alleviate the plight and tackle injustice that some of our learners and participants are subject to in their contexts.

Now in its second edition, this handbook is a current overview of second language (L2) research, providing state-of-the-art synopses of recent developments in each subarea of the field and bringing together contributions by emerging scholars and experts in second language acquisition (SLA). Since the first edition, broad sociopolitical movements, alternative views of bilingualism, emergence of global markets, vast expansion of electronic resources, the development of social media and the availability of big data have transformed the discipline, and this edition has been thoroughly updated to address these changes. It is divided into six main parts: Part I situates SLA in terms of research and practice; Part II explores individual cognitive, age-related and neurolinguistic similarities and differences; Part III outlines external, sociocultural and interactive factors; Part IV presents profiles of bilinguals who take differing paths of acquisition; Part V describes interlanguage properties; and Part VI comprises clear models of L2 development.

Since the publication of the first edition of the Cambridge Handbook of Second Language Acquisition, broad sociopolitical movements, alternative views of bilingualism, emergence of global markets, vast expansion of electronic resources, the development of social media and the availability of big data have transformed the discipline. Recent research has contributed substantial new evidence to deepen our understanding of the acquisition of a second language (L2) and its relationship to other developmental profiles, necessitating a reconsideration of the topics to be covered in a second edition. The new edition of the handbook updates earlier topics by including the latest research, in order to provide a comprehensive and current overview that represents the state of the field of second language acquisition (SLA).
