Recent studies have posited that K-12 science, technology, engineering, and mathematics (STEM) education should go beyond traditional subject silos and take an interdisciplinary approach that integrates these core subjects into a cohesive curriculum to foster authentic problem-solving skills. The purpose of this study was to field test one of five…

This program evaluation focused on the Palcare Literacy Innovation Project. The general research problem was to see if the enhanced preschool literacy project would show an improvement in the preschool classroom literacy environment, overall parent participation and a deeper connection to the community over a three-year period. The specific gap in…

Using a research design that meets the Institute of Education Sciences (IES) What Works Clearinghouse evidence standards, researchers reported the results of analyses examining the impact of the Teacher Study Group (TSG) professional development (PD) program targeting eighth grade American History teachers working with a large number of current or…

The COVID-19 pandemic has led to immediate school closures resulting in online learning. Online learning under such circumstances has presented challenges for teachers of students with mild to extensive support needs. The current study interviewed twenty special education teachers about the strategies they used when teaching online and the…

Few studies have considered academic vocabulary interventions for students who have learning disabilities (LD) and also are English learners (EL). This research explored the effects of the third year of the Creating Habits that Accelerate Academic Language of Students (CHAAOS) vocabulary intervention for eighth-grade students who received English…

This study examines the influence of a parent workshop intervention on vocabulary acquisition of at-risk preschool children during parent-child shared storybook reading. Sixty-nine parents were randomly assigned to either treatment or control group. In the treatment condition, parents were taught to implement elaborated vocabulary instruction…

Adolescents with disabilities have great difficulty with academic content in middle school, and their teachers have difficulty teaching them to understand and use academic language. We taught teachers of 6th grade students with Learning Disabilities, over half of whom were also English Language Learners (ELL), to implement about 15 minutes of…

In this study, we examined the bilingual language development among Korean American first-graders in two southern California cities and explored the opportunities for language use available to them in various spaces: at school (one dual language immersion school and one traditional English-only public school), at home, and in the community. Data…

State-funded prekindergarten (preK) programs are increasingly common across the country. This study estimated the effects of eight state-funded preK programs (Arkansas, California, Michigan, New Jersey, New Mexico, Oklahoma, South Carolina, and West Virginia) on children's learning using a regression discontinuity design. These programs vary with…

This study evaluated the efficacy of the Word Learning Strategies (WLS) supplementary program to improve elementary students' vocabulary skills and reading comprehension. The study used a multi-site cluster randomized, experimental design, which randomly assigned 92 4th grade classrooms (n=2558 students) from two cohorts to a treatment or control…

The two studies reported on in this paper examine the features of words that distinguish students' performances on vocabulary assessments as a means of understanding what contributes to the ease or difficulty of vocabulary knowledge. The two studies differ in the type of assessment, the types of words that were studied, and the grade levels and…

We conducted a randomized field trial to test an academic vocabulary intervention designed to bolster the language and literacy skills of linguistically diverse sixth-grade students (N = 2,082; n = 1,469 from a home where English is not the primary language), many demonstrating low achievement, enrolled in 14 urban middle schools. The 20-week…

Texts are a central part of reading. Yet our understandings of appropriate text features and distributions of text diets at different points in students' reading development are limited. The thesis of the essay is that, if the trajectory of struggling readers is to change, attention is needed to the features of texts and students' text diets,…
