Seven cohorts of students (N = 258) who completed a K-5 Spanish Immersion (SI) program in a suburban California school district were followed longitudinally through middle and high school to understand their academic, language, and social emotional outcomes. Academic and language outcomes included Spanish classes and grades, standardized Math and…

The longitudinal study investigated the directionality and transfer mechanism of cross-linguistic transfer of phonological awareness between L1 and L2 in predicting early writing (word dictation) in Chinese children learning English as L2. Ninety primary school Grade 1 (P1) students were assessed on phonological awareness in Cantonese (syllable…

Many second language (L2) learners participate in study abroad (SA) experiences believing their choice will be synonymous with increased interaction in the L2, from which enhanced linguistic gains will ensue. Nonetheless, one open question is whether SA participants actually engage in sustained L2 interaction while they are abroad. This paper…

This study explored the development of L2 learners' interactional competence in Arabic when making requests. Combining a longitudinal and cross-sectional design, it closely examined how learners' language proficiency affected their use of multiple requests in daily-life interactions. Participants included L2 learners (n = 40) and Saudi Arabic…

A body of previous work in second- and foreign language pronunciation instruction (e.g., Lord, 2005; Miller, 2012) has shown that explicit phonetic and pronunciation instruction is beneficial. However, Olson (2014) noted that just a few minutes per week of instruction are devoted to pronunciation in most classrooms. What is the effect of such…

Many scholars have highlighted the great variability of second language acquisition outcomes and, thus, the inconsistencies and inconclusiveness in the study abroad literature. These have called for longitudinal, case-based research that focuses on the students' processes (rather than outcomes) and that showcases the heterogeneity of…

This longitudinal quantitative study examines the first and second language vocabulary development of prekindergarten students enrolled in an inclusive foreign language exploratory (FLEX) program. The FLEX program, framed by the Cognitive Retroactive Hypothesis of cross-linguistic transfer, is situated in a context where students with special…

This article contributes to broader discussions of the knowledge base for language teacher education; the standards and policies that inform world language teacher education; and the need for a systematic, principled, and robust theory of language to underpin contexualized world language teaching and learning. Specifically, it proposes that the…

This study reports on a small-scale, longitudinal investigation on L2 Spanish oral development by English-home language (EHL) learners in an English/Spanish Two-Way Immersion (TWI) program in rural, eastern United States. It examined EHL learners' oral ability in L2 Spanish based on longitudinal assessment data from Kindergarten, Grade 2, and…

This study examined the development of requests made by second language (L2) learners of Modern Standard Arabic at four levels of L2 ability. The study used longitudinal and cross-sectional data collection to investigate how learners' performance of requests developed over a five-month period and differed as a function of ability level. The…

While study abroad homestays are often credited with providing opportunities for language and cultural learning, at times they can be characterized by communicative, cross-cultural, or interpersonal discord. In documenting these conflicts and their consequences, research to date has relied largely on students' self-reports, often focusing on their…

The assessment of dual language immersion (DLI) students' proficiency in the partner language plays a key role in program evaluation. This article reports findings from a large-scale study, drawing on cross-sectional assessment data from 73 schools and longitudinal data from 25 schools. Students were tested in the interpretive (listening and…

Recent surveys and research on second language (L2)/foreign language acquisition help explain the challenges that postsecondary students in lower-level foreign language (FL) courses may experience. The present study extends this line of research by examining changes in students' affective profiles in a two-year Japanese program (n = 382) at an…

Educators have generally believed that foreign language instruction should begin in kindergarten or earlier to promote optimum oral language development (e.g., Abbott, 1998; Curtain & Dahlberg, 2010; Rhodes & Pufahl, 2010; Rosenbusch, 1991; Swender & Duncan, 1998). This article describes two Spanish programs in the Westport…

The article aims at investigating speech processing prerequisite claims made by Pienemann's Processability Theory (1998). Longitudinal data from eight English L1 and one French L1 speaker learning Arabic as an L2 were used to investigate the emergence/processing of demonstrative-predicate gender agreement and verbal agreement structures…
