Purpose: There is limited research on the writing of young Spanish-English bilinguals and their writing in both languages. In the current study, we addressed whether written syntax features differed by language (English and Spanish) and varied as a function of grade level, English learner status, and instructional program (dual or English…

Many studies conducted in the last decades report that very few elementary-grades students understand the meaning of = in mathematics, and that upper-elementary students do not understand it any better than the lower-elementary students do. Using data from thousands of Florida elementary students, we show that students in Florida perform ten to…

A substantial amount of evidence suggests that students, particularly those from economically disadvantaged households, experience summer reading loss. Available evidence suggests this is due to a lack of participation in literacy-focused activities and access to books during the summer break from school. The current study investigated whether…

The construct of reading comprehension has changed significantly in the 21st century, however, some test designs have not evolved sufficiently to capture these changes. Specifically, the nature of literacy sources and skills required has changed (wrought primarily by widespread use of digital technologies). Modern theories of comprehension and…

This policy brief addresses the question: How long does it take English learners (ELs) to attain English proficiency and exit EL services? The researchers analyzed statewide longitudinal data from students who entered Oregon schools as ELs in kindergarten between 2006-07 and 2012-13. Using discrete-time survival analysis, the results of this study…

Understanding students' misconceptions and how they change is an essential part of supporting students in their science learning. This paper presents results from distractor-driven multiple-choice assessments that target students' misconceptions about energy. Over 20,000 elementary, middle and high school students from across the U.S. participated…

We investigated the dimensionality and relations between L1 (a speaker's first language) and L2 (a speaker's second language) writing skills in narrative and informational genres and higher order cognitive skills--inference, perspective taking, and comprehension monitoring--for Spanish-English dual language learners in primary grades. Dimensions…

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…

This paper reports results from a large-scale observational study investigating attention allocation during instructional activities in elementary school students (kindergarten through fourth-grade). In Study 1, 22 classrooms participated while a more diverse sample of 30 classrooms participated in Study 2. This work investigated temporal patterns…

This meta-analysis extends previous work on extensive Tier 3 type reading interventions (Wanzek & Vaughn, 2007; Wanzek et al., 2013) to Tier 2 type interventions by examining a non-overlapping set of studies addressing the effects of less extensive reading interventions for students with or at risk for reading difficulties in Grades K-3. We…
