Although researchers have found strong relationships between first language (L1) skills and second language (L2) anxiety, less is known about how L1 skills in primary school impact L2 anxiety years after L1 has been acquired. Previous research lacked evidence for the mediating role of L2 aptitude and L2 achievement in the relationship. This study…

Previous research used the learning hierarchy (LH) as a heuristic to select reading interventions based on the level of accuracy defined as the percentage of words read correctly. The current study examined the validity of the LH by reporting the prevalence of reading profiles proposed by the framework: Acquisition phase--inaccurate and slow,…

Research shows that targeted interventions for language comprehension and production benefit the development of English language proficiency and literacy skills of English Learner (EL) students. Despite this, many ELs in the United States do not receive such academic support, as few programs are designed to address the needs of ELs. Educational…

Students' proficiency in the language of instruction is essential for their mathematical learning. Accordingly, language-responsive instruction, which includes adapting teaching material to students' language needs, is thought to promote mathematical learning, particularly for students with lower levels of proficiency in the language of…

Language-responsive instructional approaches are intended to enhance the mathematics learning of students with low academic language proficiency, mostly by enriching mathematical content trajectories with systematic language-learning opportunities. However, little is known about their effects (and in particular differential effects) in…

Multilingual learners (MLs) encounter key language features that influence their mathematical word problem-solving processes. Much of the readily available literature surrounding MLs' experiences in the mathematics classroom explores either their content knowledge or how language affects their mathematics achievement. Far less literature has…

Morphological awareness is essential for language and literacy development, yet its underlying structure remains unclear, especially in Chinese-English bilinguals at different ages. This study tested 467 hong Kong bilingual children in Grades 2, 5, and 8 on their morphological awareness in both Chinese and English. Confirmatory factor analysis was…

This study explores the relationship between English Learners (ELs) in the Texas school system and their outcomes on the State of Texas Assessments of Academic Readiness (STAAR) tests and the Texas English Language Proficiency Assessment System (TELPAS). Schumann's Acculturation Model and Krashen's Input Hypothesis were used as theoretical…

New California reporting requirements drawing attention to outcomes for Long-Term English Learners (LTELs) opens a window of opportunity for changes to better support these students. In spring 2023, the Stanford-Sequoia K-12 Research Collaborative (Sequoia Collaborative) agreed to key changes in the reclassification process for multilingual…

Research involving secondary school EFL learners has demonstrated that greater intensity of exposure, via CLIL lessons, yields notable benefits. However, studies in primary school are scarce and less optimistic. Furthermore, little is known about the effects of different degrees of CLIL intensity and of learners' exposure to Extramural English…

Research on the effects on early bilingualism on reading development is scarce. Here, we tackle this question by investigating whether the exposure to dual-language contexts (use of two languages in the same conversational situation) induces a boost in phonological and reading performance through more balanced spatial auditory attentional skills.…

This article examines the impact of within-class age differences on educational outcomes, using students' birth months in Madrid's primary schools as a natural experiment. Employing a regression discontinuity design, we analyze third-grade students to investigate these age-related effects. Additionally, we explore whether early childhood education…

Young, linguistically diverse learners often leverage multimodality to more fully express their ideas in writing. To better support and assess English writing development, it is vital to understand multimodality as part of their emerging writing skills. In this study, we examine how drawings and written language are used jointly in multimodal…

Most English learners (ELs) eventually gain sufficient English proficiency to be reclassified and receive instruction without linguistic supports. Though well-identified, prior regression discontinuity estimates for the effect of reclassification are estimated too imprecisely to detect policy-relevant effects. Applying a student fixed-effect…

In this preregistered within-teacher randomized controlled trial (n = 84), we tested the effects of grouping English learners (ELs) in homogeneous groups (all ELs) versus heterogeneous groups (ELs and non-ELs) on language, reading comprehension, and argumentative writing. Findings indicated no significant main effects of grouping. However,…
