Purpose: The current study examined (a) the relation between morphologically complex word (MCW) use (words containing at least one derivational morpheme such as prefixes and suffixes) and teachers' ratings of writing quality, (b) average change in MCW use in writing across the school year, and (c) differential change in MCW among students with…

Pedagogical scaffolding offers temporary support as English Learners engage with challenging math. We identify three dimensions--grouping, structure, and language--along which teachers can vary the intensity of scaffolding with the same rigorous prompt to challenge and support their English Learners. [This paper was published in "Mathematics…

This article presents a case study of a dual-language learner (DLL) preschooler in three classroom conversations: whole group, small DLL group, and a teacher-child dyadic conversation. By comparing the student's interactions across three contexts, the authors show how dyadic conversations between teachers and students can foster the oral language…

Theoretical models have posited that social contexts influence parental attitudes, which in turn modulate parental behaviors. The current study asks whether parental attitudes on bilingualism differ by local language context and whether parents who perceive bilingualism as more valuable are more likely to engage in activities with their child in…

Multitiered systems of support hold promise for dual language learners when culturally and linguistically responsive practices guide instruction. We modeled growth on Spanish and English early literacy skills and examined the role of language exposure and use at the individual and classroom instruction level in a group of 313…

Purpose: Language sampling is a critical component of language assessments. However, there are many ways to elicit language samples that likely impact the results. The purpose of this study was to examine how different discourse types and elicitation tasks affect various language sampling outcomes. Method: A diverse group of K-3 students (N =…

Research Findings: Children's oral language skills lay the foundation for later literacy and can be fostered through responsive conversations with teachers. However, such conversations are rare in preschool, particularly between teachers and dual language learners (DLLs), or students who speak a minoritized language at home. DLLs benefit when…

Purpose: Few caregiver-implemented naturalistic language interventions (NLIs) are available for Spanish-speaking Latinos who have young children under 3 years with language delays, and there is a scarcity of studies that provide information about intervention development or social validity of interventions for this group. This study introduces…

This paper explores a general approach to paraphrase generation using a pre-trained seq2seq model fine-tuned using a back-translated anatomy and physiology textbook. Human ratings indicate that the paraphrase model generally preserved meaning and grammaticality/fluency: 70% of meaning ratings were above 75, and 40% of paraphrases were considered…

Previous studies offer mixed evidence regarding whether a unified model of reading comprehension predictors applies to Dual Language Learners (DLLs) and English Speakers (ESs), or whether distinctive models across language groups are empirically supported. The present study adds another dimension to this body of work by examining multiple reading…

In this study, we elicited grammatical forms (oral production) from a group of child heritage speakers of Spanish (N = 45) in English and Spanish, using the morphosyntax subtest of the Bilingual English-Spanish Assessment (BESA), (Peña et al. 2014). A cross-sectional design was used with 25 participants in kindergarten and 20 in first grade. All…

Purpose: The purpose of the current study was to examine the role that the first language (L1), Spanish, at Pre-Kindergarten plays in predicting second language (L2), English, word reading in first grade. In addition, it examines the role of conceptual vocabulary in predicting word reading in English. Method: As part of a longitudinal study of…

Using a nationally representative sample of dual language learners (DLLs) attending Head Start, this study investigated how the language used for instruction and the proportion of DLLs in the class was associated with English and Spanish receptive vocabulary development between the fall and spring (n = 531). Based on teacher report of the language…

Many educators and policymakers look to two-way dual language immersion as one of the most promising options to close achievement gaps for English learners. However, the programs' effectiveness depends on the quality of their implementation. This article reports on a large-scale study of the implementation of dual language immersion across a…

This study investigates the potential for linguistic microfeatures related to length, complexity, cohesion, relevance, topic, and rhetorical style to predict L2 writing proficiency. Computational indices were calculated by two automated text analysis tools (Coh- Metrix and the Writing Assessment Tool) and used to predict human essay ratings in a…
