This report evaluates the effects of Lexia[TM] Core5[TM] Reading (Core5) -- a product of Lexia Learning Systems -- on the reading achievement of students in grades 3-5 during the 2021-2022 academic year. Core5 is a program that focuses on various student literacy skills, such as fluency, vocabulary, and comprehension. This report represents the…

METRICS was a 5-year grant program funded by the U.S. Department of Education designed to immerse elementary school students in computer science. METRICS components included 1) creation and implementation of rigorous computer science curriculum units and assessments to support STEM coursework connected across all subjects through problem-based…

The Assessment-to-Instruction (A2i) Professional Support System has been shown to be effective in improving literacy proficiency among young readers by combining data-driven technology with professional development (PD) activities to help teachers provide personalized literacy instruction. To identify efficient ways to expand the reach of A2i,…

This applied experimental research tested the effectiveness of a universal, student-focused intervention ('Memory Mates'), specifically focused on supporting students to use attention and working memory strategies within academic contexts, unlike computer-based programs. Memory Mates is presented in the form of icons and explanations, with the…

"Fraction Face-Off!" is a supplemental math program designed to support fourth-grade students who need assistance solving fraction problems. Teachers use program materials with individual students or small groups to promote understanding of the magnitude of fractions, to compare two fractions, to put three fractions in order, and to…

In this article, we introduce the term "vulnerability to achievement stressors," which refers to differentially low achievement when shifts in the educational environment "stress" or threaten the capacity of an individual or a group of individuals to make academic progress. We also introduce a methodological framework for…

Despite substantial cross-national interest in remedial programming as a way to support low-achieving students, evidence of its effectiveness is rare, particularly in low-income and/or crisis-affected contexts. In this article, we present experimental evidence of the impact of a remedial tutoring program on academic outcomes from a two-level…

Large numbers of U.S. students lack proficiency in science, and students from different racial/ethnic and socioeconomic groups show disparities in science achievement. Science knowledge and skills are important for both academic and workplace success, and a variety of interventions have been developed to improve student achievement in science.…

Policymakers have long sought to raise expectations for students through standards-based reform. I examine the extent to which the Common Core State Content Standards (CC) affected student achievement and the size of achievement gaps. I merge together data on preparation for and implementation of the CC with the National Assessment of Educational…
