The Programme for International Student Assessment (PISA) is an international comparative study that assesses how well 15-year-olds, who have nearly completed compulsory schooling in most participating educational systems, can use their knowledge and skills to meet real-world opportunities and challenges. In each cycle of PISA, students are…

The main aim of this research was to investigate the impact of reducing the number of components on overall performance in GCSE subjects. In particular, researchers were interested in how the grade achieved by candidates on a reduced number of components compares to their grade on the full qualification. This research mainly looked at GCSEs with…

(Purpose) This study aimed to evaluate the efficacy of Imagine Math by comparing the performance of program users and non-users on the NWEA MAP Growth Math assessment. (Methods) Propensity score matching was utilized to compare statistically similar southeastern U.S. charter school students who used or did not use the Imagine Math program during…

Analysis of consistent Zearn Math users and a comparable group of low- or non-users, across 6 districts in Nebraska, shows that students who used Zearn Math consistently had higher levels of academic growth than similar students with low- or no-usage. For this analysis, 784 students who completed an average of 3+ Zearn Math lessons per week,…

Analysis of consistent Zearn Math users and a comparable group of non-users in a large Southern district shows that students who used Zearn Math had higher levels of academic growth than similar students with no usage. This analysis used the quasi-experimental method, Coarsened Exact Matching (CEM), to examine the impact of Zearn Math across 1,111…

The pivotal role of Algebra in the educational trajectories of U.S. students continues to motivate controversial, high-profile policies focused on when students access the course, their classroom peers, and how the course is taught. This random-assignment partnership study examines an innovative district-level reform--the Algebra I…

Purpose: The purpose of the study was to evaluate the implementation and impact of the IDEA Public Schools' Mathematics Curriculum Redesign (MCR) effort, funded by an Innovation and Research (EIR) grant. Methods: The study used a quasi-experimental matching design to examine the effect of MCR on student achievement outcomes. The study compared…

These are the appendixes for the report, "What Grade 7 Foundational Knowledge and Skills Are Associated with Missouri Students' Algebra I Achievement in Grade 8?" To increase opportunities for students to take more advanced math courses in high school, many school districts enroll grade 8 students in Algebra I, a gateway course for…

The engage2learn approach to educator support provides an in-person and virtual coaching system that builds capacity and engagement in public schools. Engage2learn hired LXD Research to conduct an independent evaluation and analysis of NWEA Math and Reading data collected during the 2021-2022 school year. The goal was to measure how engage2learn…

The current project, Exploring Math Education Relations by Analyzing Large Data Sets (EMERALDS) II, is an attempt to identify specific Common Core State Standards procedural, conceptual, and problem-solving competencies in earlier grades that best predict success in algebraic areas in later grades. The data for this study include two cohorts of…

The Lyceum, implemented by Guilford County Schools (GCS), was an arts education program designed to promote arts integration for all GCS students and exposure to Entertainment Arts & Technology for students at Penn-Griffin School for the Arts. The Lyceum impact evaluation used a quasi-experimental design (QED) to examine the effect of…

Over the years, the nation's large urban school districts have consistently learned from the progress of their peer districts across the country. Great City School districts that have embraced the challenge of educating America's urban children have recognized the value of benchmarking their performance and growth against the progress of others.…

This study uses high school transcript data from the National Assessment of Educational Progress (NAEP) High School Transcript Study (HSTS) to determine the validity of student-reported high school courses on the NAEP twelfth-grade student questionnaire. Given that the HSTS is not administered as part of every NAEP twelfth-grade assessment,…

The National Center for Education Statistics (NCES) has periodically published reports using results from the National Assessment of Educational Progress (NAEP) to compare the proficiency standards states set for their students. Since standards vary across states, the results of the various state assessments cannot be used to directly compare…

These are the technical notes for "Mapping State Proficiency Standards onto the NAEP Scales: Results From the 2017 NAEP Reading and Mathematics Assessments." The National Center for Education Statistics (NCES) has periodically published reports using results from the National Assessment of Educational Progress (NAEP) to compare the…
