The purpose of this technical appendix is to more fully describe the sample, methods, and results of the research brief "Boys Regain the Advantage in Middle School STEM Skills: Post-COVID Trends in Gender Achievement Gaps." The authors investigated three research questions in this brief: (1) How have 8th grade gender gaps in STEM…

In the last two decades, the US has made remarkable strides in closing long-standing gender inequities in academic achievement in STEM (science, technology, engineering, and math) fields. However, new data suggest these hard-won gains may be unraveling. During the COVID-19 pandemic, girls showed substantially larger declines in math and science…

Educational inequality is a highly debated yet empirically understudied topic in Malaysia. This paper examines the patterns and trends of academic achievement gaps by student social groups in Malaysia, drawing upon nationally representative data for the most recent four cohorts (1999, 2003, 2007, and 2011) of eighth-grade Malaysian students from…

Potential differences in achievement between female and male students have always been an interesting topic in educational research, as well as having policy and economic implications. This study provides an overview of the so-called "gender gap" in mathematics and science knowledge, based on an in-depth analysis of both extremes of…

Has the gap in average standardized test scores between students from high- and low-income families widened, narrowed, or remained stable over the last 3 decades? The question is important both because the achievement gap is measure of how (un)equally educational opportunities are distributed in the US, and because the disparity in educational…

The 2011 NAEP-TIMSS linking study conducted by the National Center for Education Statistics (NCES) was designed to predict Trends in International Mathematics and Science Study (TIMSS) scores for the U.S. states that participated in 2011 National Assessment of Educational Progress (NAEP) mathematics and science assessment of eighth-grade students.…

Are U.S. and, in particular, Hoosier students competitive and ready to succeed in an ever-changing and increasingly global economic landscape? This question is frequently considered by K-12 education stakeholders at all levels, including national, state, and local officials. One of the central ways in which education systems can compare themselves…

The U.S. Congress has mandated that the National Center for Education Statistics (NCES) produce an annual report to help inform policymakers about the progress of education in the United States. Using data from across the center and from other sources of education data, "The Condition of Education 2015" presents 42 key indicators on…

To help inform policymakers and the public about the progress of education in the United States, Congress has mandated that the National Center for Education Statistics (NCES) produce an annual report, "The Condition of Education." This year's report presents 42 indicators on important topics and trends in U.S. education. These…

A recent study in the USA documented the existence and growth of "excellence gaps" among students. These gaps are similar to the minimum competency achievement gaps that proliferate in policy discussions in many Western countries, but excellence gaps focus on the highest level of achievement rather than minimum competency. We extend this…

Research on educational quality has been scarce in the Middle East and North Africa (MENA) region, whereas the debates over educational quality date from 1966 in the USA with the Coleman Report. Fortunately TIMSS (Trends in International Mathematics and Science Study) starts to fill this gap by providing data on students' achievement and for many…

Using data from the Trends in International Mathematics and Science Study (TIMSS) 2003 and 2007 administrations, this study examines international trends in technology use and explores the international patterns in how teacher-directed, student-use of technology is related to eighth grade mathematics achievement. Descriptive patterns in…

For more than 50 years, the International Association for the Evaluation of Educational Achievement (IEA) has been conducting comparative studies of educational achievement in a number of curriculum areas, including mathematics and science. TIMSS 2011 represents the fifth cycle of the Trends in International Mathematics and Science Study (TIMSS),…
