Introduction
Appli ed linguistics is a broad, evolving, interdisciplinary field of language and language-related study across diverse social contexts (e.g., Cook, 2003; Davies & Elder, 2004; Hall, Smith, & Wicaksono, 2011; Kaplan, 2010; Pawlak & Aronin, 2014; Phakiti & Paltridge, 2015; Schmitt, 2002; Simpson, 2011). This diversity, while a strength of the field, occasions disagreement in how applied linguistics should be defined. Part of the reason for this is that, as de Bot (2015) points out, the word linguist as used in the term applied linguist often leads to the misunderstanding that applied linguists simply “apply” linguistic knowledge but most applied linguists would agree that this is hardly ever the case, as due to its interdisciplinary nature, applied linguistics as a field of study sits at the intersection of a diversity of fields.
Research fields that are related to and influence applied linguistics research include linguistics, psychology, philosophy, education, and sociology. Furthermore, several terms, such as appliable linguistics (Mahboob & Knight, 2010) and applied language studies (Richards, Ross, & Seedhouse, 2012), are used interchangeably with applied linguistics, contributing to the richness of debates over the definition of applied linguistics.
Evolution of Applied Linguistics Research
Applie d linguistics is a relatively youthful field which emerged in the latter of half of the twentieth century; one of the field’s flagship journals, Applied Linguistics, published its first issue in 1980 and others are of even more recent vintage. There are common terms that underlie applied linguistics research (e.g., language, linguistics, language learning, real-world language use, and language in social contexts), and there are several subdisciplines under the applied linguistics umbrella (e.g., first and/or second language acquisition/learning, language teaching and education, language assessment, and bilingualism/multilingualism). In each of these subdisciplines, researchers ask and address different research problems, employing a variety of philosophies and methodologies.
In his pursuit to address the definition and scope of applied linguistics, de Bot (2015) employed interviews and questionnaires with approximately 100 applied linguists. Key questions included “what is applied linguistics?”, “who are the key players?”, and “who influences them and whom do they influence in turn?”. de Bot also traces the main trends that have driven and impacted on applied linguistics in the past 30 years, including social and dynamic turns and the adoption of various paradigms in the field.
The primary intent of this Handbook, however, is not to resolve existing difficulties in defining applied linguistics. Rather, the Handbook has been driven by, and builds on, current work in applied linguistics research, and it aims to contribute to the advancement of research methodology in applied linguistics with a particular focus on supporting the access of early career researchers and emerging scholars to the rich diversity of research approaches currently being deployed in th...
