In this paper, we review how eye tracking, which offers millisecond-precise information about how language learners orient their visual attention, can be used to investigate a variety of processes involved in the multifaceted endeavor of second language acquisition (SLA). In particular, we review the last 15 years of research in SLA, in which…

Mathematics has been defined by researchers as a 'second or third language' and, as a result, it should be taught as a second language. Results of the literature reviewed from the theories on the teaching of mathematics and English as a second language, as well as on mathematics learning and English as a second language acquisition, have resulted…

This longitudinal study examined whether and to what extent the production of voice onset time (VOT) for /p/, /t/, and /k/ in English was improved in second language (L2) learners by enrolment in a content-based instruction (CBI) program at a Japanese university. Measures of VOTs were elicited at the beginning, middle, and end of the academic year…

Energy Conservation Theory of Second Language Acquisition (ECT-L2A) (Han, Bao, & Wiita, 2017b), an interdisciplinary theory juxtaposing a physics perspective and an applied linguistics perspective, conceptualizes individuals' ultimate attainment as a function of dynamic transformation of endogenous and exogenous energies throughout the…

This study was designed to firstly develop a corpus of Indonesia's junior high school (JHS) and senior high school (SHS) English textbooks (TB) and national examination (NE) texts. By means of corpus analysis, this study then attempted (1) to find out the vocabulary levels (i.e. distribution among the K1-K20, where K refers to 1000-word band in…

Very little research has been conducted on the effects of CLIL on L1 competence development. This article compares CLIL and non-CLIL learners' levels of attainment in Spanish Language and Literature in seven public schools in the South of Spain. Learners' verbal intelligence and motivation were previously matched in order to homogenise the sample.…

Geography lessons center on a language-based product with socially relevant geographic content. The subject of geography in secondary schools in Germany faces three major challenges that make a stronger focus on language in the monolingual geography classroom necessary. First, more than 30 percent of German pupils in secondary schools have a…

Understanding and working with the complexity of second language learning and use in an intercultural orientation necessitates a re-examination of the different theories of learning that inform the different schools of second language acquisition (SLA). This re-examination takes place in a context where explicitly conceptualizing the nature of…

Over the last 40 years, there have been successive attempts to define or refine a set of key concepts intended to guide theory and experimentation in SLA. These include "input," "intake," and "consciousness." This article tries to take these attempts a stage further by integrating the conceptualization of these notions into a larger…

This book is about the prospect of a social turn in the field of second language acquisition (SLA), in particular, that part of SLA that is devoted to the input-interaction-output (IIO) model. The book is intended to critically examine some of the basic notions and assumptions that underpin this model and to suggest a more interdisciplinary and…
