Given the growing number of Latino English learners and the lack of evidence-based educational opportunities they are provided, we investigated the impact of one potentially effective literacy intervention that targets struggling first-grade Spanish-speaking students: Descubriendo La Lectura (DLL). DLL provides first-grade Spanish-speaking…

Background: South African primary school learners have participated in several national and international literacy (reading and writing) studies that measure learners' achievement in different grades and at different intervals. Numerous scholars have analysed the results of these assessments. We extended their analyses by investigating the grade…

Using a cluster-randomized controlled trial research design, this study investigates the effect of the first year of a three-year teacher professional development program on grades 1 and 2 student achievement in mathematics. Although the findings reported in the present report do not meet the standard cutoff for statistical significance (e.g., 95%…

This technical report is an addendum to a study we initially reported on in 2014 (Wray, Lai, Saez, Alonzo, & Tindal, 2014). In response to a request for additional analyses, in particular reporting confidence intervals around the results, we re-analyzed the data from the Wray et al study. This supplementary report presents the results of the…

Despite the coronavirus pandemic, HIPPY expanded geographically to provide services to parents of 601 children zoned to 114 elementary schools during the 2020--2021 academic year, compared to 105 schools during the previous year. Commencing in March 2020, the program was consistently delivered using a hybrid format (face-to-face and virtual), with…

This paper provides a secondary analysis of the May, Sirinides, Gray, and Goldsworthy (2016) evaluation of the Reading Recovery scale-up. We extend their findings to include analysis of the six subscales of the "Observation Survey (OS) of Early Literacy Achievement" (Clay, 2013) that the What Works Clearinghouse has previously used to…

Equitable assessment of students' mathematical thinking is imperative for effective instruction. This two-part study investigated teachers' judgement of students' mathematical thinking. In Study One, we used a national data set to determine the correlation between teachers' judgement of students' mathematical thinking and scores from a…

This paper presents an evaluation of two reading methods, phonics-based instruction and whole language learning, for English Language Learners (ELLs) and discusses the learning theories, behaviorism and constructivism that are associated with each method, respectively. The study took place in a K-12 international school, with 110 Grade 1 subjects…

This three-year longitudinal study tracked the reading performance of 68 kindergarten students from low SES backgrounds. These students received instruction with a blended learning program--Lexia® Core5® Reading--from the start of kindergarten through second grade. During each school year the students made significant gains on a standardized…

Because schools often do not begin formal processes to identify students with gifts and talents until the third grade, many kindergarten through second-grade teachers face challenges in identifying and meeting the needs of these learners. We examined gifted education plans from a sample of seven districts in and around the Charlotte, North…

After decades of conflict with Indonesia, Timor-Leste is gradually rebuilding its education infrastructure and reclaiming its identity as an independent country. In the first decade post-independence the education sector faced many challenges, including a lack of school buildings and resources, the need to replenish and upskill the Timorese…

Despite the claim by several researchers that variability in performance may complicate the identification of "at-risk" children, variability in the academic performance of young children remains an undervalued area of research. The goal of this study is to examine the predictive validity for future scores and the score stability of two…

This study examined the role of initial skill in moderating intervention effects of a 50-lesson mathematics intervention program, ROOTS, for at-risk kindergarten students focused on developing whole-number concepts and skills. The study utilized a randomized block design with at-risk students (n = 592) within classrooms (n = 60) randomly assigned…

Value-added assessment methods have been criticized by researchers and policy makers for a number of reasons. One issue includes the sensitivity of model results across different outcome measures. This study examined the utility of incorporating multivariate latent variable approaches within a traditional value-added framework. We evaluated the…

Assessing students' emerging literacy skills is crucial for identifying areas where a child may be falling behind and can lead directly to an increased chance of reading success. The Waterford Assessment of Core Skills (WACS), a computerized adaptive test of early literacy for students in prekindergarten through 2nd grade, addresses this need.…
