The COVID-19 pandemic prompted schools to transition to remote instruction during the latter half of the 2019-20 school year and continuing into the 2020-21 school year. National Assessment of Educational Progress (NAEP) data trends indicate that there were statistically significant declines in students' mathematics and reading scores between 2020…

In this article, we extend Liao's test for across-group comparisons of the fixed effects from the generalized linear model to the fixed and random effects of the generalized linear mixed model (GLMM). Using as our basis the Wald statistic, we developed an asymptotic test statistic for across-group comparisons of these effects. The test can be…

The Programme in International Student Assessment (PISA) has become the prominent method of international comparison of the achievement of 15-year-old children in reading, mathematics, and science. Recently, the OECD, which administers PISA, has devoted a great deal of energy promoting the notion of "academic resilience"--which refers to…

Regions with a lengthy summer break can create negative outcomes for learners; this problem is referred to as summer learning loss, summer learning gap, or summer slide. Summer learning loss is loss of academic knowledge and skill that accumulates over the break from school. When students return to school after the summer break, teachers need to…

During the COVID-19 pandemic, the very youngest pupils in schools had their schooling and social interactions in the classroom disrupted by lengthy periods of school closures and remote learning. This research focuses particularly on these young pupils, and is exploring how their learning and social skills are recovering two years on from the…

School closures resulting from the COVID-19 pandemic have brought the issue of learning loss to the forefront in what has been called the "COVID slide." Data from the pandemic show a decline in student achievement in the areas of reading and mathematics for school districts that shifted to virtual learning platforms. However, it is…

To make up for pandemic-related learning losses, many U.S. public school districts have increased enrollment in their summer school programs. We assess summer school as a strategy for COVID-19 learning recovery by tracking the academic progress of students who attended summer school in 2022 across eight districts serving 400,000 students. Based on…

The National Assessment of Educational Progress (NAEP) is an integral measure of academic progress across the nation and over time. It is the largest nationally representative and continuing assessment of what our nation's students know and can do in various subjects, such as civics, mathematics, reading, and U.S. history. The program also…

About one in five students in the US attends a rural school, and over half of all school districts are in rural areas. And yet very little is known about achievement, achievement gaps, and academic growth in rural schools, including how school-year and summer changes in achievement may differ in these schools. This lack of information is…

Australia participated in the eighth cycle of the Trends in International Mathematics and Science Study (TIMSS). TIMSS is an international sample study that assesses the mathematics and science achievement of Year 4 and Year 8 students every 4 years. Australia has participated in all cycles of TIMSS since it commenced in 1995 and over this 28-year…

The purpose of this technical appendix is to share more detailed results and to describe more fully the sample and methods used in the research included in the brief, "The Widening Achievement Divide during COVID-19." The authors investigated two main research questions in this brief: (1) To what degree have students' reading and math…

Virginia governor Glenn Youngkin and his administration want to raise the bar for students to pass the state's standardized tests "from the lowest in the nation to the highest in the nation" by next spring. His goal is to close the "honesty gap" between the 79 percent of Virginia students who pass the state's tests and the 39…

This presentation was an invited address at the opening session of the 2021 Annual Conference for the Advancement of Science Teaching (CAST) in Ft. Worth, Texas. The presentation will investigate student achievement using three perspectives. The presenters will first ask if one could recognize a great teacher. They will then report research…

By age 18, students have spent on average 85 percent of their waking hours outside of school. Their use of that time--constructive or not--helps direct their futures. In afterschool and summer programs, young people explore new interests, develop new skill sets, and create lasting relationships with peers and caring adults that shape who they are,…

To ensure each county board of education provides a thorough and efficient education for its students, the West Virginia Board of Education (WVBE) annually reviews county scorecards and efficiency profiles provided by the Office of Accountability. County statuses are reviewed and determined based on multiple measures of student performance and…
