NCES 2023054 PIRLS 2021 U.S. Highlights Web Report

The Progress in International Reading Literacy Study (PIRLS) is an international comparative study that measures 4th-grade reading performance every 5 years. PIRLS provides valuable information on the reading literacy of students in the United States and how their reading performance compares to that of students in other parts of the world. The study also surveys students’ attitudes toward reading and their reading habits. In addition, students’ principals answer questions about students’ school experiences. The United States has participated in every administration of PIRLS since its inception in 2001. A total of 65 education systems participated in the 2021 PIRLS assessment.

This web report presents descriptive data from PIRLS 2021 on school operations during COVID-19, student reading performance and attitudes, and school reading resources.

NCES 2022041 Changes Between 2011 and 2019 in Achievement Gaps Between High- and Low-Performing Students in Mathematics and Science: International Results From TIMSS
This Statistics in Brief (SiB) uses data from the 2011 and 2019 Trends in International Mathematics and Science Study (TIMSS), and explores how achievement gaps between high- and low-performing 4th- and 8th-grade students in the U.S. and other education systems have changed over time. Achievement gaps are defined as the differences in scores between students at the 90th percentile of performance (high-performing) and those at the 10th percentile of performance (low-performing); they are also known as “score gaps.” The SiB focuses on two questions for each grade and subject: (1) In which education systems did score gaps between high- and low-performing students change (widen or narrow) between 2011 and 2019? (2) Is the widening or narrowing of score gaps between 2011 and 2019 driven primarily by changes in the scores of high-performing students, low-performing students, or both?

WWC 2021012 Math Expressions
This WWC intervention report summarizes the research on Math Expressions, a core curriculum for elementary school students that aims to build students' conceptual understanding of mathematics and to develop fluency in mathematical problem solving and computation. The curriculum encourages student learning of mathematics through real-world situations, visual supports such as drawings and manipulatives, multiple approaches to solving problems, and opportunities for students to explain their mathematical thinking. Based on the research, the WWC found that Math Expressions has no discernible effects on general mathematics achievement for students in grades 1 and 2, relative to other math curricula used in study schools.

NCES 2021021 TIMSS 2019 U.S. Highlights Web Report
The Trends in International Mathematics and Science Study (TIMSS) 2019 is the seventh administration of this international comparative study since 1995, when it was first administered. TIMSS is administered every 4 years and is used to compare the mathematics and science knowledge and skills of 4th and 8th-graders over time. TIMSS is designed to align broadly with mathematics and science curricula in the participating countries. The results, therefore, suggest the degree to which students have learned mathematics and science concepts and skills likely to have been taught in school. In 2019, there were 64 education systems that participated in TIMSS at the 4th grade and 46 education systems at the 8th grade.

The focus of this web report is on the mathematics and science achievement of U.S. students relative to their peers in other education systems in 2019. Changes in achievement over the last 24 years, focusing on changes since 2015 and 1995, are also presented for the U.S. and several participating education systems. In addition, this report describes achievement gaps within the United States and other education systems between top and bottom performers, as well as among different student subgroups.

In addition to numerical scale results, TIMSS also reports the percentage of students reaching international benchmarks. The TIMSS international benchmarks provide a way to understand what students know and can do in a concrete way, as each level is associated with specific types of knowledge and skills.

NCES 2017002 Highlights from TIMSS and TIMSS Advanced 2015: Mathematics and Science Achievement of U.S. Students in Grades 4 and 8 and in Advanced Courses at the End of High School in an International Context
The Trends in International Mathematics and Science Study (TIMSS) 2015 is the sixth administration of this international comparative study since 1995 when first administered. TIMSS is used to compare over time the mathematics and science knowledge and skills of fourth- and eighth-graders. TIMSS is designed to align broadly with mathematics and science curricula in the participating countries. The results, therefore, suggest the degree to which students have learned mathematics and science concepts and skills likely to have been taught in school. In 2015, TIMSS was administered in 49 IEA member countries and 6 other education systems at grade 4, and in 38 IEA member countries and 6 other education systems at grade 8.

TIMSS Advanced assesses the advanced mathematics and physics knowledge and skills of students at the end of high school who have taken courses in advanced mathematics and physics. TIMSS Advanced 2015 represents only the second administration in which the United States has participated since the first administration in 1995, and is designed to align broadly with the advanced mathematics and physics curricula in the participating countries. The results, therefore, suggest the degree to which students have learned the advanced mathematics and physics concepts and skills likely to have been taught in school. Nine countries participated in TIMSS Advanced 2015.

The focus of the report is on the performance of U.S. students relative to their peers in other countries on TIMSS and TIMSS Advanced 2015, and, for TIMSS results, on changes in achievement since 2011 and 1995. For a number of participating countries and education systems, changes in achievement can be documented over the last 20 years, from 1995 to 2015. This report also describes the characteristics of students who participated in the advanced mathematics and physics assessments at the end of high school, and describes the performance of males and females in these subjects. In addition, it includes achievement in Florida, a U.S. state that participated in TIMSS both as part of the U.S. national sample of public and private schools as well as individually with state-level samples of public schools.

In addition to numerical scale results, TIMSS also includes international benchmarks. The TIMSS international benchmarks provide a way to interpret the scale scores by describing the types of knowledge and skills students demonstrate at different levels along the TIMSS scale.

Additional tables with TIMSS and TIMSS Advanced results will be available on the NCES website at http://nces.ed.gov/timss/timss15.asp.
