This study examines the impact of instructor-led (IL) versus self-access (SA) web-based pragmatic instruction on novice second language learners' (n = 28) awareness and oral production of Spanish apologies. Two sections of a second-semester Spanish course were assigned to either the IL or the SA group. The web-based resource "Dancing with…

In this single-case study with a quasi-experimental design, we set out to examine the role of two input-based features of the language learning app Duolingo on learners' development of implicit and explicit second language (L2) knowledge. We investigated the effect of Duolingo's Stories feature and Podcast feature on two Spanish-L2 learners'…

Over past decades, there has been a paradigm shift in WL instruction, moving away from traditional, grammar-based programs and toward instruction that promotes student proficiency in the target language. Despite this growing attention to proficiency-based instruction, few studies have investigated the relationship between proficiency-based…

Research has indicated that lexical richness is an important indicator of second language (L2) proficiency. However, most research has examined written, cross-sectional English L2 corpora and does not necessarily indicate how spoken lexical use develops over time or whether observed trends are stable across L2s. This study adds to previous…

Using a structural equation modeling approach, this study investigates the structural relationships between second language (L2) oral proficiency and interest in learning the target language (L2 interest), in the presence of potential mediating variables (i.e. perceived importance of speaking, out-of-class contact with L2 resources). It also…

The ACTFL Oral Proficiency Interview--computer (OPIc) employs a self-assessment instrument to determine the nature of the speaking prompts to which the test taker will respond and, thus the difficulty of the test. Grounded in research demonstrating varying levels of accuracy in self-assessment among language learners, this study examines the…

This systematic review aims to explore how task complexity and task sequencing affect the complexity, accuracy, and fluency (CAF) of second language performance. Through an analysis of studies conducted between 2012 and 2021, this review investigates the characteristics of the studies, operationalisation of task complexity, measurements of CAF,…

This aptitude-treatment interaction study investigated the extent to which explicit and implicit cognitive abilities are differentially related to learning outcomes under two corrective feedback conditions. One hundred and thirteen intermediate English learners of Spanish were randomly assigned to an implicit feedback (recast), explicit feedback…

While discourse markers (DMs) are crucial for coherence and interactional competence, previous research suggests that learners' usage of DMs differs from L1 speakers. Prior research has taken either a discourse-functional or interactional approach, yet combining these two methods may provide greater understanding of the unique learner…

orInverse relations, or "trade-off effects," are a common outcome of interlanguage development: a learner may increase performance in one linguistic domain while simultaneously decreasing performance in another. In this study, we investigate the relationships between one aspect of fluency (pause usage) and two aspects of syntactic…

Feature-based approaches to acquisition principally focus on second language (L2) learners' ability to perceive non-native consonants when the features required are either contrastively present or entirely absent from the first language (L1) grammar. As features may function contrastively or allophonically in the consonant and/or vowel systems of…

Higher education Spanish programs in the United States are diverse and complex, especially when it comes to student linguistic background. However, most studies on language proficiency were designed for traditional learners (L2s). In this study, we examine oral proficiency development of 125 Spanish majors in light of four linguistic profiles:…

This study employed qualitative methods to explore how the "UVA in Valencia Summer Program 2019/2021" approached instructional practices (e.g., in-class and out-of-class immersive learning activities, homestays, pre-program services, including use of L2 and culture learning strategies) to identify those features of the program design…

Although most children learn to communicate in their first language (L1), there is normal and expected variation in their rate of acquisition across all components of the language system. Until recently, most second language acquisition and second language (L2) researchers have assumed that individual differences (IDs) in L1 acquisition are small…

This study explored the influence of speech rate (normal vs. fast), sentence length (short vs. long), and second language (L2) oral proficiency on listening comprehension in L2 Spanish. Thirty-one native English-speaking learners enrolled in upper-level Spanish courses were aurally exposed to 8 sentences of each type of speed--length matrix, for a…
