Regarding the English language skills, speaking seems to be the most crucial skill in terms of communication or interaction in daily lives (Ur, 1996). This present study aimed to investigate factors enhancing English speaking ability, also the most influential factor affecting speaking ability. The participants were 5 high school students who had…

The purpose of the present study was to compare the effects of input flooding and input elaboration on the learning of non-congruent collocations by Iranian English as a foreign language (EFL) learners. The participants of the study included 60 EFL learners at the intermediate level of language proficiency who were divided into two equal groups.…

Any policy that aims to solve the challenges of language teaching and learning must include language assessment research. Language assessment has shown a lot of development in terms of the scientific implications of assessing language capacity for the purposes of advising judgments about people and reviewing language programs (Bachman, 2000). The…

From the current available research, it is evident that further evidence is needed to understand Second Language Acquisition (SLA) processes under planned bilingualism approaches in English as a Second Language (ESL) environments. This study employs an explanatory single case strategy to investigate the oral proficiency and SLA experiences of a…

This article addresses the benefits of audio-visual input for learning second language (L2) vocabulary and grammatical constructions. Specifically, it explores the role of frequency, the effects of subtitles and captions, and the mediating role of learner proficiency on language gains in two longitudinal studies. Study 1 targets vocabulary…

When viewed through a generic, one-size-fits-all perspective, use of input enhancement does not appear effective. Through analysis of individual grammatical features and different learner proficiency levels, a significant impact may be revealed. To study the impact of input enhancement on diverse grammatical features, 16 short reading texts and…

In response to the recent sharp increase of L2 students in Reykjavik schools, allocation criteria for special L2 services were adopted that were based on length of residence and on whether children's home language was tonal or not tonal. This study set out to evaluate the appropriateness of these criteria, and to replicate previous findings of a…

This study conducted a mixed-method study of the influence of audio and video input mode on free-recall listening performance. It first explored quantitatively whether input mode significantly influenced 34 sophomores' performance in general and across two genres (passage and long dialogue) and three ranks of idea units (the discourse topic, main…

This article explores what kind of second language (L2) input influences Japanese learners' acquisition of adjective ordering restrictions (AOR) in English where Japanese exhibits no AOR. In Study I, an explicit instruction (EI) group (n = 13) and a natural exposure (NE) group (n = 12) responded to a preference task. In Study II, an input flood…

The aim of this study was twofold: first, to develop an experimental technique as a tool to investigate learning outcomes of spontaneous, naturalistic second language (L2) learning under controlled laboratory conditions; and second, to explore how this technique can be used to understand the basic conditions and limits of this learning. Two…

This book examines the role of interlocutors and their individual differences (IDs) in second language (L2) development from four theoretical lenses: the cognitive-interactionist approach, sociocultural theory, the variationist approach, and complex dynamic systems theory. A theoretical overview to each approach is written by a preeminent scholar…

A recurring question in the literature of heritage language acquisition, and more generally of bilingual acquisition, is whether all linguistic domains are sensitive to input reduction and to cross-linguistic influence and to what extent. According to the Interface Hypothesis, morphosyntactic phenomena regulated by discourse-pragmatic conditions…

This book offers an evidence-based guide to EAL for everyone who works with multilingual learners. It provides a concise, helpful introduction to the latest research underpinning three key areas of EAL practice: (1) How children acquire additional languages? (2) How language works across the curriculum? and (3) How you can establish outstanding…

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…

The current project longitudinally investigated the extent to which first-year Japanese university students developed their second language (L2) oral ability in relation to increased input in foreign language classrooms. Their spontaneous speech was elicited at the beginning, middle and end of one academic year, and then judged by linguistically…
