Language proficiency is multi-componential in nature and, according to many SLA researchers and L2 practitioners, is best captured by the concepts of complexity, accuracy, and fluency (CAF). Two of the three studies reported in this paper adopted the Cognition Hypothesis (Robinson, 2003) as the means to address the question of whether increasing…

Young people from refugee backgrounds in Australia face numerous barriers to successful tertiary education. One key challenge is developing critical literacy skills beyond basic language proficiency. Critical literacy empowers students to understand power relations, critique underlying assumptions and explore issues of belonging -- factors crucial…

In this article, we study a simple mathematical model of a bilingual community in which all agents are fluent in the majority language but only a fraction of the population has some degree of proficiency in the minority language. We investigate how different distributions of proficiency, combined with the speakers' attitudes toward or against the…

Addressing themes from the Douglas Fir Group's (2016) transdisciplinary framework, this paper bridges boundaries between cognitive and social disciplines by showing how social contextual factors can affect the psycholinguistic development of complexity, accuracy, and fluency (CAF) in learner language. Sociolinguistic and sociocultural frameworks…

In Vietnam, language teaching and learning have recently been a concern of not only educators and language learners but also parents and families who have school-aged children. When finding a suitable language course, language learners and their families tend to ask questions about the nativeness of the teachers and their language fluency. Being a…

English learners (ELs) represent a large and rapidly growing proportion of US public school students. Federal law requires public schools to provide ELs with linguistic supports necessary to equalize their access to instruction with that of native English-speaking students. Most ELs are eventually reclassified and receive instruction within a…

Over the past 40 years, Jim Cummins has proposed a number of highly influential theoretical concepts, including the threshold and interdependence hypotheses and the distinction between conversational fluency and academic language proficiency. In this book, he provides a personal account of how these ideas developed and he examines the credibility…

English Learners are an important part of California's K12 student population. Over 40 percent of students in California's K-12 education system speak a language other than English at home. Almost half of these students are considered English Learners (ELs), meaning they require additional language and academic support to succeed in school. In…

In this paper, in contrast to previous neuroimaging literature reviews on first language (L1) and second language (L2), the focus was only on neuroimaging studies that were directly conducted on multilingual participants. In total, 14 neuroimaging studies were included in our study such as 10 functional magnetic resonance imaging, 1 positron…

Former English Learner students who have improved their facility with English to such a degree that they have been reclassified by their school districts as fluent in the English language are among the best performing students in the state. Because these Reclassified Fluent English Proficient (RFEP) students have much better academic outcomes than…

There is a growing awareness of the importance of academic vocabulary, and more generally, of academic language proficiency, for students' success in school. There is also a growing body of research on the nature of the demands that academic language places on readers and writers, and on interventions to help students meet these demands. In this…

Comprehensibility, a major concept in second language (L2) pronunciation research that denotes listeners' perceptions of how easily they understand L2 speech, is central to interlocutors' communicative success in real-world contexts. Although comprehensibility has been modeled in several L2 oral proficiency scales--for example, the Test of English…

This study provides specific evidence regarding the extent to which quantitative measures, common sense notional measures, and comprehensive measures adequately characterize spontaneous, although engaged, speech. As such, the study contributes to the growing body of literature describing the current limits of automatic systems for evaluating…

This longitudinal study investigates the development of writing proficiency in English as a foreign language (EFL), in contrast to the development of first language (L1) writing proficiency in Dutch L1, in a sample of almost 400 secondary school students in the Netherlands. Students performed several writing tasks in both languages in three…

This paper investigates the intergenerational transmission of language capital among immigrants, and the effect of language deficiencies on the economic performance of second-generation immigrants. Using a long panel that oversamples immigrants, we can follow their children after they have left the parental home. Our results show a sizeable…
