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'…

This study investigates the acquisition and maintenance of periphrastic and se-passives in second language (L2), heritage (HS), and (Spanish-dominant) native Spanish speakers (NS) by addressing: (i) How accessible are Spanish periphrastic passives (which also exist in English) and se-passives (unique to Spanish) for L2ers and HSs in production?…

In this paper a context where receptive multilingualism represents a communicative strategy of adjustment in a context of second language acquisition is discussed. The traditional scope of receptive multilingualism has been extended to multilingual environments resulting from an experience of mobility, namely transnational adoptive families.…

This study examined the receptive vocabulary knowledge and lexical developmental patterns of the 3000 most frequent words among 953 university L2 learners of Spanish at different stages in their language studies, taking into consideration the effect of high school instruction on high-frequency vocabulary knowledge. Results confirm that even…

Recent literature in the field of L2 vocabulary assessment has advocated for the development of written receptive vocabulary tests such as Vocabulary Levels Tests (VLTs) that use: (a) meaning-recall item formats, (b) a minimum of 40 item counts per 1,000-frequency band to improve level estimates, and (c) lemmas (not word-families) as the lexical…

Bilingual children demonstrate varying levels of proficiency in each of the two languages to which they are exposed. Even though it is widely acknowledged that bilingual children are not a homogenous group, existing studies on dual-language profiles in bilingual children have focused on expressive language profiles. In this study, we used the…

This study examined linguistic development among both intermediate and advanced college-level second language (L2) learners during short-term study abroad summer programs in Spain. Participants completed a measure of overall proficiency, as well as assessments of receptive grammatical (morphosyntactic) and lexical (semantic) abilities at the…

It is well-documented that there is a strong relationship between vocabulary and reading comprehension in school-age children. Limited vocabulary knowledge can impact a student's reading achievement, as may be the case for school-age English Learners (ELs). This study aims to analyze the role of vocabulary in predicting reading comprehension…

To date, several studies have investigated the potential benefits of using Quizlet and podcasts for vocabulary development. However, they have mainly focused on the use of available material, and its effects on receptive vocabulary acquisition and students' motivation. In contrast, relatively little has been done to study the effects of…

Hundreds of millions of language learners around the globe study a second language with popular apps such as Duolingo, Rosetta Stone, Busuu, and Babbel. This study examined the effectiveness of one app, Babbel, for developing both receptive linguistic knowledge of vocabulary and grammar, as well as oral communicative ability in Spanish as a second…

This article extends two conversations in the heritage language (HL) scholarship: 1) the need to strengthen the linguistic self-confidence among receptive bilinguals (who are typically associated with beginning-level HL students); 2) the need for more critical explorations of receptive bilinguals' self-reported, albeit minimal, spoken Spanish in…

Spanish-English bilingual learners are the fastest growing demographic in U.S. elementary schools. Yet many schools, particularly those in new immigration destination regions, continue to measure bilingual students' vocabulary using monolingual norms. This inequitable practice makes it appear as if bilingual learners have lower language abilities…

Purpose: Elementary-age dual language learners (DLLs) from Spanish-speaking homes in the United States are often characterized as at risk for low vocabulary in both Spanish and English. This longitudinal study examined conceptually scored receptive and expressive vocabulary development among DLLs from Spanish-speaking, low-income homes and…

This article examines factors that promote active multilingualism. For this purpose, the "Peabody Picture Vocabulary Test" was used with 48 children. Their results were linked to a parental questionnaire designed to evaluate the children's linguistic input in their immediate environment. The study shows that, besides a minimum amount of…

Purpose: First, we sought to extend our knowledge of second language (L2) receptive compared to expressive narrative skills in bilingual children with and without primary language impairment (PLI). Second, we sought to explore whether narrative receptive and expressive performance in bilingual children's L2 differed based on the type of contextual…
