This study examines how second/foreign language (L2) word difficulty estimates derived from item response theory (IRT) and classical test theory (CTT) frameworks are virtually identical in the context of vocabulary testing. This conclusion is reached via a two-stage process: (a) psychometric assessments of both approaches and (b) L2 word…

Besides explicit inference of word meanings, associating words with diverse contexts may be a key mechanism underlying vocabulary learning through reading. Drawing from distributional semantic theory, we developed a text modification method called reflash to facilitate both word-context association and explicit inference. Using a set of left and…

This article sheds light on the linguistic and extralinguistic conditions that determine the likelihood of L1 grammatical attrition in late sequential bilinguals. We explore whether aspectual interpretations associated with the present tense may be a vulnerable area for the native grammar of 30 late Spanish-English bilinguals who have settled in…

This article reports the findings of a study undertaken to document and explain the use of English in signage in Costa Rica, a Spanish-speaking country. The linguistic landscape has emerged as an important, viable field of research. In order to investigate how, when, and why the use of English manifests itself, a corpus of 169 photographs of signs…

In our article, we investigate the complex dynamics of linguistic understandings and mis- or non-understanding within multilingual contexts. Through the lens of sociolinguistic exploration, we navigate the multifaceted landscapes of language use, applying a multi-perspective approach and the triangulation method to explore the depths of linguistic…

"Variability" and "fractality," two key concepts in Complex Dynamic Systems Theory (CDST)--the former concerning changes and variations, and the latter concerning recursiveness and self-similarities--may seem contradictory at first glance. This forum piece attempts to elucidate how the two seemingly contradictory properties can…

There has been increasing L3 research on L3 transfer selectivity, especially concerning which factor triggers crosslinguistic influence during L3 acquisition. According to Slabakova's (2016) Scalpel Model, every linguistic property has distinct and unique input factors regarding L3 acquisition such as high/low frequency or positive/negative input.…

Globally classrooms are increasingly linguistically diverse. Research often oversimplifies lived linguistic heterogeneity as binary variables: native versus non-native. Linguistic distance (LD) measures allow a fine-grained operationalization of linguistic diversity in foreign language education. This study investigated associations of cognate LDs…

The prevalent use of ELF in global communication necessitates a rethinking of what theoretical frameworks and methodological approaches are appropriate to explain the changing and complex nature of intercultural interactions, particularly, those whereby English is recognised as a passport. This review accounts for ELF interactions in terms of…

Much empirical research on textbook analysis has been undertaken. However, little evidence with regard to the adoption of SLA findings in the textbook analysis was reported, particularly for the Indonesian EFL textbooks. To fill this void, this study aimed at analyzing a textbook endorsed by the Indonesian Ministry of Education and Culture,…

This paper discusses collaborative ethnographic work investigating multilingualism within education in Botswana, Tanzania, and Zambia. The paper takes a reflective perspective on how research is conducted and the role that multilingualism and collaboration can play in the research process itself. As a team of thirteen individuals, working across…

To date, there has been mounting research evidence on the impact of written corrective feedback. In response to this, reviews have been conducted to condense either findings or methodologies through the combined analysis of EFL and ESL studies. Although syntheses shed light on the topic, no one provides exclusive insights into EFL realities.…

This book adopts as conceptual focus the technical mode of experience, exploring this characteristic mode of design as the angle from which the discipline of applied linguistics takes its cue. What makes applied linguistic concept formation possible? A number of elementary concepts and ideas are so basic to the discipline that they can neither be…

This study brings together two previously largely independent fields of multilingual language acquisition: heritage language and third language (L3) acquisition. We investigate the production of fortis and lenis stops in semi-naturalistic speech in the three languages of 20 heritage speakers (HSs) of Italian with German as a majority language and…

Research shows many problems and ambiguities of second language acquisition (SLA), which have made learners and readers worldwide unsatisfied. Therefore, this study attempts to highlight theories and research that have comprehensive explanations of the problems and ambiguities of second language acquisition, which learners of English as a Foreign…
