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'…

The multidimensional conceptualization of vocabulary knowledge has been extraordinarily influential in lexical research. Yet, the few studies that have empirically explored the structure of word knowledge conflict regarding its multidimensionality. The present study examines the nature of L2 vocabulary knowledge by exploring how the hypothesized…

The purpose of the current study was to examine the influence of L1 (i.e. Spanish) receptive vocabulary on both expressive and receptive knowledge of target vocabulary words taught through L2 (i.e. English) instruction and intervention. Participants were Bilingual US kindergarten students determined to be at-risk based on English receptive…

In this exploratory study, we considered the method of combining event-related potentials (ERPs) and source attributions as a means for examining the explicit or implicit nature of second language (L2) knowledge and processing. We recorded electroencephalograms while L2 Spanish participants judged phrase structure and subject-verb agreement…

Oral language is foundational to literacy. Because their language is under construction, emergent bilingual students have unique needs related to literacy development regardless of the language of instruction. Knowledge teachers gain through formative assessment of student oral language can guide decisions about literacy instruction. The purpose…

This paper describes a study exploring in-service (IS) and pre-service (PS) teachers' language ideologies about non-Spanish-speaking students' multilingualism in Chilean classrooms. A survey was answered by 69 IS teachers and 34 PS teachers in the Chilean school system. Both groups were asked about two dimensions: (a) teachers' knowledge and…

A quantitative research study was conducted to understand the extent to which gamification (i.e., game elements and mechanics) impact adult learners' satisfaction (in terms of app usability), perception, motivation and knowledge when they interact with a gamified mobile app on Spanish-as-a-foreign language learning. An online experimental study…

Parental satisfaction is often used "as one indicator of school success or one outcome of school effectiveness". However, the notion that it is possible to gauge minoritized parental satisfaction in schools without first understanding their educational beliefs and values about education and their knowledge about the US school system is…

This study explored the experiences of eight Latina heritage speakers (HSs) who were enrolled in world language teacher preparation programs at two higher education institutions. Using data from interviews, classroom observations, and other documents, the qualitative multiple-case study investigated their educational experiences and the challenges…

This article uses the clitic left dislocation (CLLD) construction in L2 Spanish to investigate whether generative SLA has valuable insights to contribute to language teaching. Although CLLD is a structure that is commonly used by native speakers, as reported anecdotally and in at least one corpus, we found that native-Spanish and native-English…

The prior language knowledge of learners for whom the target language is not the first foreign language poses a different starting learning situation that should merit pedagogical attention. The present paper seeks to contribute to the question of which pedagogical considerations can be made in regard to the role of prior language knowledge beyond…

Individual differences (IDs) largely contribute to success in adult second language attainment (e.g., Dörnyei, 2006). Heritage language (HL) studies have also explored the role of IDs, namely psychosocial variables, and biographical factors with an adult HL learner population. However, the specific contribution of these variables to HL learners'…

This paper investigates students' performance in content-subjects in the framework of CLIL programmes in Spain. So far, CLIL research has focused primarily on language attainment in the L2 and the L1, but students' achievements as regards content-subjects have been largely ignored. Competence in Science in the L1 is analysed by comparing pupils…

Recent changes to federal education laws for students with and without disabilities have kindled an increased interest in implementing evidence-based practices for teaching academic skills to all students, including students with severe disabilities and students learning English. Teaching students with significant disabilities who are learning…

We report on the use of bilingual constructed response science assessments in the context of a research and development partnership with secondary school science teachers. Our project provided a series of workshops for teachers where they explored students' emergent reform-oriented science meaning-making in our project-designed assessments. We…
