Purpose: The ongoing COVID-19 pandemic has prompted changes to child assessment procedures in schools such as the use of face masks by assessors. Research with adults suggests that face masks diminish performance on speech processing and comprehension tasks, yet little is known about how assessor masking affects child performance. Therefore, we…

The rising demand for dual-language immersion (DLI) programs, which offer core instruction in two languages from early grades onward, has raised questions about program design and access. We leverage the rapid expansion of DLI schools across the U.S. state of Utah to estimate effects of DLI program availability on the academic achievement of…

Nearly two dozen states now administer online exams to deliver testing to K-12 students. These tests have real consequences: their results feed into accountability systems, which have been used for more than a decade to hold schools and districts accountable for their students' learning. We examine the rollout of computer-based testing in…

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 =…

More than 40 percent of students in California's public schools speak a language other than English at home. In the 2016-17 school year, 21 percent of all students, or more than 1.3 million, were English Learners (ELs). When former English Learners are included, the population of "ever ELs" expands to 38 percent of all K-12 students in…

General measures of process quality are widely used in the early childhood education (ECE) field. However, the evidence regarding associations between the most widely used process quality measure, the Classroom Assessment Scoring System (CLASS; Pianta et al., 2008), and children's school readiness gains during the preschool year is mixed. Using…

Despite the prevalence of educational apps for children, there is little evidence of their effectiveness for learning. Here, children were asked to learn ten new words in a narrative mobile game that requires children use knowledge of word meanings to advance the game. Study 1 used a lab-based between-subjects design with middle-SES 4-year-olds…

This study examined the longitudinal prediction of decoding, oral reading fluency (ORF), and bilingual language proficiency (BLP) on student reading comprehension (RC) outcomes in Spanish and in English. Participants were first-grade Latinx students attending bilingual programs. Findings indicated that BLP initial status and gains were significant…

English learners' (ELs) day-to-day experiences in school change when reclassified as fully English proficient. Prior research, however, is mixed on how reclassification influences outcomes. Many studies also do not or cannot explore key long-term outcomes or identify impacts over time. In this study I leverage longitudinal student data in a…

The measurement of self-regulation in young children has been a topic of great interest as researchers and practitioners work to help ensure that children have the skills they need to succeed as they start school. The present study examined how a revised version of a commonly used measure of behavioral self-regulation, the…

This study evaluated the efficacy of the Word Learning Strategies (WLS) supplementary program designed to develop upper-elementary students' vocabulary skills in order to improve reading comprehension. The study used a true, group-randomized, experimental design, which randomly assigned 46 4th grade classrooms (n=1324 students) from 12 districts…

Purpose: This study evaluated the efficacy of an instructive feedback strategy for modeling letter names and sounds during presentation of positive feedback within a small group phonological awareness intervention for preschoolers. Method: Two experiments were conducted using multiple baseline designs across children and behaviors. Letter name and…

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…

This study explores whether linguistic features can predict second language writing proficiency in the Test of English as a Foreign Language (TOEFL iBT) integrated and independent writing tasks and, if so, whether there are differences and similarities in the two sets of predictive linguistic features. Linguistic features related to lexical…

Purpose: The purpose of the present study was to evaluate the efficacy of a phonological awareness (PA) intervention, designed for Tier 2 instruction in a Response to Intervention (RTI) model, delivered to small groups of preschoolers. Method: A multiple-baseline design across participants was used to evaluate the efficacy of the intervention on…
