This study examined the initial efficacy of World Generation (WorldGen), a Tier I social studies instructional approach for emergent bilingual (EB) students and their native English-speaking (non-EB) peers in Grades 6 and 7. WorldGen builds on prior research on instructional practices that have been associated with improved content knowledge and…

Determining the effectiveness of core mathematics curricula is foundational to evidence-based practice. Examining effectiveness heterogeneity is also crucial to better understanding mathematics achievement among English language learners (ELLs). In this study, we used a quasi-experimental design (difference-in-differences) to examine the impact of…

We examine the effects of a read aloud replication intervention designed to improve the vocabulary, comprehension, and expository and narrative language outcomes of first grade students. Thirty-nine first-grade classrooms from 12 schools were randomly assigned to a treatment (n = 19) or comparison condition (n = 20). Teachers in the treatment…

The goal of this study was to assess the relationships between computational approaches to analyzing constructed responses made during reading and individual differences in the foundational skills of reading in college readers. We also explored if these relationships were consistent across texts and samples collected at different institutions and…

A primary objective of development is to build a knowledge base. To accumulate knowledge over time and experiences, learners must engage in productive processes, going beyond what is explicitly given to generate new knowledge. Though important to accumulating knowledge, these processes are also easily disrupted. Individuals often depend on surface…

Theory of Mind (ToM), as a relevant aspect in children's socio-cognitive development, has been widely studied. Some results have suggested that bilingual children have an advantage over their monolingual peers in development of ToM. However, there is less research regarding the predictive role of ToM in performance of oral and reading…

The linguistic interdependence hypothesis (Cummins, 1979, 2000) states that children's second-language (L2) proficiency is, to some extent, a function of their first-language (L1) competence. Previous studies have examined this hypothesis with focus on a unidirectional relation from L1 to L2. In the present study, we examined…

Research examining effective reading interventions for students with reading difficulties in the upper elementary grades is limited relative to the information available for the early elementary grades. In the current study, we examined the effects of a multicomponent reading intervention for students with reading comprehension difficulties. We…

This study investigated: 1) the influence of alphabet instructional content (letter names, letter sounds, or both) on alphabet learning and engagement of English only and dual language learner (DLL) children, and 2) the relation between children's initial status and growth in three underlying cognitive learning processes (paired-associate,…

We describe research results and lessons learned from a laboratory/ classroom collaboration with a school system offering both traditional English-only education and a dual-language track (Spanish/English). Through this collaboration, we addressed basic research questions informing malleable factors that impact cognitive development. In a…

Research has demonstrated that students in dual-language immersion programs perform as well as, or better than, their peers in core academic content areas by late elementary school. The extent to which immersion education fosters bilingualism, however, has received less attention in the literature. Using data from a four-year efficacy study of…

The English Language and Literacy Acquisition--Validation (ELLA-V) study was a five-year evaluation of a program that provided professional development, coaching, and curricula that targeted English-as-a-second-language (ESL) instruction for teachers of K-3 English learners (ELs). ELLA-V was implemented in 10 school districts in Texas in the…
