Modelling ability is one of the essential elements of the latest educational reforms, and Trends in International Mathematics and Science Study (TIMSS) is a curriculum-based assessment which allows educational systems worldwide to inspect the curricular influences. The aims of this study were to examine the role of modelling ability in the…

Literature has established that some learners encountered difficulties solving first order ordinary differential equations (ODEs). The use of error analysis in teaching ODEs is believed to make essential contribution towards calculus knowledge development. This paper therefore focuses on analyzing pre-service teachers' (PSTs) errors and…

This article examines the conceivable rationales as to why Korean students' English-speaking proficiency scores are not as outstanding as other international standardized test scores such as the Trends in International Mathematics and Science Study (TIMSS) and the Program for International Student Assessment (PISA). Despite the efforts of the…

This paper evaluates the impact on dropout rates of a policy change in Mexico that eliminates grade retention for all first to third-grade students, causing a sharp reduction in repetition rates. I use a 12-year panel of schools to exploit such variation and estimate Difference-in-Difference models showing an average decrease in dropout rates of…

Without a conceptual understanding of fraction magnitude, students have difficulties understanding more advanced mathematics in high school and beyond. The purpose of this study is to highlight 4th and 8th grade students' misconceptions in fraction magnitude using the Trends in International Mathematics and Science Study 2015 data. The study is…

School-level inefficiencies and mismanagement can have serious repercussions for human resource development and labor market outcomes. This paper investigates the extent and consequences of existing technical inefficiency of schools with respect to their resource- and people-management aspects at a cross-country level across Organisation for…

This report provides an update on the state of the research on testing accommodations. Previous reports by the National Center on Educational Outcomes (NCEO) have covered research published since 1999. In this report, we summarize the research published in 2020. During 2020, 11 research studies addressed testing accommodations in the U.S. K-12…

The National Center for Education Statistics (NCES) conducted a special administration of the National Assessment of Educational Progress (NAEP) long-term trend (LTT) reading and mathematics assessments for age 9 students in 2022 to examine the impact of the COVID-19 pandemic on student learning. This brief document highlights the score declines…

This study introduces the signal weighted teacher value-added model (SW VAM), a value-added model that weights student-level observations based on each student's capacity to signal their assigned teacher's quality. Specifically, the model leverages the repeated appearance of a given student to estimate student reliability and sensitivity…

The goal of this study was to further evaluate the impact of IXL Math on math learning outcomes. Using a quasi-experimental design with matched treatment and control groups, this analysis utilized data from 312 public schools in Mississippi during the 2021-2022 school year. The middle school analysis included 272 schools (136 treatment, 136…

School-based learning experiences are often designed with the "typical" student in mind. However, this may not be an optimal approach, given the variability of prior learning that exists in most classrooms. We investigated the variance in achievement within U.S. fourth- and eighth-grade mathematics classrooms using Trends in…

Problem Roulette (PR), an online study service at the University of Michigan, offers points-free formative practice to students preparing for examinations in introductory science, technology, engineering, and mathematics courses. Using four years of PR data involving millions of problem attempts by thousands of students, we quantify the benefits…

Cignition delivers virtual tutoring in math and ELA, led by experienced educators. Their approach focuses on data-informed instruction and collaborative learning that encourages student-to-student interaction to build students' conceptual understanding. After a 2020 efficacy study of its 1:1 math tutoring offering, Cignition developed a group…

Lebanon has been participating in the Trends in International Mathematics and Science Study assessment (TIMSS) since 2003, however, data indicate a continuous decline in performance of Grade 8 students. The purpose of this study is to examine the factors critical to the achievement of Lebanese Grade 8 students and investigate the reasons for their…

Background: Socioeconomic characteristics are persistently and systematically related to academic outcomes, despite long-standing efforts to reduce educational inequality. Ireland has a strong policy focus on alleviating educational disadvantage and has seen significant improvements in mathematics and science performance in recent years. This…
