Montessori is a highly individualized pedagogy that prioritizes following each child's individual interests over standardized test scores. This quasi-experimental study compares groups of Montessori students (treatment groups, N = 535-710) with control groups of non-Montessori students, matched through the simple matching method, which controls…

In recent years, there has been a growing interest in spatial reasoning as a component of mathematics education, with many countries incorporating it into their mathematics curriculum. The study of spatial reasoning in the learning areas of geometry presents an essential opportunity for improvement of students within the realm of mathematics…

This study investigates the relationship between mastery goal performance and achievement on the State of Texas Assessments of Academic Readiness (STAAR) test. With policies like the Every Student Succeeds Act (ESSA) placing increased importance on standardized-state assessments, schools are making efforts to improve scores, often by focusing…

The purpose of this ex-post facto quantitative study was to compare English Language Arts (ELA) and math Tennessee Compressive Assessment Program (TCAP) scores of students in grades four through eight who attended school virtually or in-person during the 2020-2021 school year. Due to the COVID-19 pandemic, the school district in this study allowed…

This quantitative, causal-comparative research study investigated whether school configuration has an impact on the reading performance of sixth-grade students by comparing the End-of-Grade (EOG) reading assessment Grade Level Proficiency (GLP) scores of sixth-grade students in K-8 configured schools to sixth-grade students enrolled in 6-8 grade…

Do grade configurations affect student academic performance? To bring new evidence to this question, I use recent district-by-grade data for nearly the entire United States that contain measures of test score achievement and rates of school switching induced by grade configuration. Past research has found that student performance, is, on average,…

We study a decade of achievement gaps for fifth-, eighth-, and 10th-grade students in Norway using administrative population data. Norway is a wealthy and egalitarian country with a homogeneous educational system, yet achievement gaps between students at the 90th and 10th percentiles of parental income and between students whose parents have at…

This quantitative, correlational study aimed to investigate the relationships between collective teacher efficacy (CTE), its enabling conditions (EC-CTE), and student achievement in third through eighth grades in Colorado. Leveraging the theoretical foundations established by Rotter (1954), Bandura (1977) and expanded by Tschannen-Moran et al.…

The purpose of the current research study was to investigate the extent to which student performance was influenced by the disruption to learning that occurred due to the COVID-19 pandemic. To explain observed differences in performance, we compared outcomes from a state-wide summative testing program between students who were administered the…

The purpose of this quantitative non-experimental cross-sectional study was to examine the possible relationship between students' autonomy, students' competence, and student-teacher relatedness, and their performance on ELA and math high-stakes tests. The self-determination theory was employed to guide the study. This study collected…

In October 2023, the California Department of Education released test scores for all students in Grades 3-8 and 11 for the 2022-23 school year. These results represent an opportunity to analyze whether and to what extent student learning has rebounded after the dramatic declines in scores resulting from the COVID-19 pandemic and related school…

This paper presents results of a score interpretation study for a computer adaptive mathematics assessment. The study purpose was to test the efficacy of item developers' alignment of items to Range Achievement-Level Descriptors (RALDs; Egan et al.) against the empirical achievement-level alignment of items to investigate the use of RALDs as the…

Part of learning a new discipline is learning the language used in the discipline. For mathematics, emergent multilingual learners (EML) must learn English and mathematical symbols in order to make meaning and communicate. The mathematics community's understanding of communication is complex and includes the use of natural language, incorporation…

In this brief we examine how variability in students' math and reading test scores changed across the pandemic, including whether increased dispersion was concentrated at one part of the test score distribution. Using reading and math assessment data from a sample of 8 million students in grades 3-8 in 24,000 public schools who took MAP Growth…

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…
