The Mindsets mathematics program addresses the challenge of engaging middle school students in rigorous, grade-level math by making mathematical reasoning relevant, collaborative, and accessible. This research examines how the program uses hands-on, real-world challenges to promote engagement and deep understanding while meaningfully improving…

This study is the first to explore the impact of the Illustrative Math (IM) curriculum on student math performance. IM is one of the nation's most widely adopted high-quality math curricula. Using survey, state, and public town data from districts in Massachusetts, researchers explored how student math performance changed in 71 schools after they…

This study examines the qualitative outcomes of a geometry intervention program implemented in 2023 in an Israeli elementary school for fifth- and sixth-grade students. The program was unique in its use of emotional support strategies in geometry instruction to improve students' mathematics achievement, reduce math anxiety, and increase their…

Background/purpose: This study examines the effectiveness of Jordan's National Program for Remedial Interventions (NPRI) in mathematics, launched in response to the COVID-19 pandemic, by analyzing its implementation mechanisms, remedial content, and impact on student performance from the perspective of mathematics teachers. Materials/methods: The…

With increasing pressure on schools to boost students' math scores post-pandemic, this study investigates the impact of a tech-enhanced formative assessment that incorporates the instruction of strategic thinking in math to foster learning. Employing mixed methods, the impact of a one-year implementation of Classtime on state test scores was…

Scholars and practitioners have called for personalized and widely accessible professional development (PD) for teachers. Yet, a long-standing tension between customizing support and increasing access to such support has hindered the scale-up of high-quality PD for individual teachers. This study addresses this challenge by developing a…

This study explored whether initial skill moderated outcomes of Promoting Algebra Readiness, a Tier 2 sixth grade mathematics intervention targeting conceptual and procedural knowledge of fractions. The study analyzed data from a quasi-experimental pilot study in which at-risk students (n = 198) were assigned to the treatment or control condition…

This study explored whether initial skill moderated outcomes of Promoting Algebra Readiness, a Tier 2 sixth-grade mathematics intervention targeting conceptual and procedural knowledge of fractions. The study analyzed data from a quasi-experimental pilot study in which at-risk students (N = 198) from Oregon middle schools were assigned to the…

A one-on-one dialogue-based mathematics intelligent tutoring system (ITS) for learning multiplication and division of fractions was developed and evaluated in this study. This system could identify students' error types and misconceptions in real-time by using a block-based matching method. The adaptive dialogue-based instruction was supported by…

Background: An efficacy study based on a randomized controlled trial (RCT) was designed to evaluate the impact of ASSISTments on math learning among middle school students, including those from high-needs rural schools. Despite extensive recruitment efforts in 2021 (during the pandemic), only a few schools and their teachers agreed to participate,…

This is a technical report detailing the analytic methods used to assess the effects of a virtual professional learning community (vPLC)-enhanced ASSISTments intervention. The report uses a quasi-experimental design and partially nested regression model to account for clustering and reveals that while overall effects were positive but not…

This report is a companion to the "Scaling Teachers' Professional Development for ASSISTments: Evaluation Final Report" and presents an in-depth look at how the integration of the ASSISTments platform with a virtual professional learning community (vPLC) supported middle school math teachers in improving instruction, fostering student…

The aim of this study was to develop, implement, and evaluate an intervention program focusing on developing Grade 5 and 6 students' functional thinking. The innovative aspect lies in addressing simultaneously various aspects of function--input--output, covariation, correspondence, and object--in terms of manipulating tasks that involve functional…

Background/Context: The Education Innovation and Research (EIR) grant program provides funding for creating and implementing innovative approaches to improving student achievement while rigorously evaluating the approach. The STEM.LD program was funded by a 2020 mid-phase EIR grant. It was designed in response to a growing need for individuals…

The aim of this study is to investigate the effectiveness of Realistic Mathematics Education Strategies Mobile App (REMSAM) on the mathematical problem solving performance of students with learning disabilities (LD). The participants of this study consisted of five children (three girls, two boys) with LD. The study was carried out based on a…
