In cognitive diagnosis assessment (CDA), the impact of misspecified item-attribute relations (or "Q-matrix") designed by subject-matter experts has been a great challenge to real-world applications. This study examined parameter estimation of the CDA with the expert-designed Q-matrix and two refined Q-matrices for international…

Researchers explored how 13 states in which policymakers have adopted an A-F school letter grade accountability system performed on the National Assessment of Educational Progress (NAEP) post-policy implementation. Researchers found mixed results, with approximately half of these 13 states increasing achievement post-policy, and the other…

The purpose of the study is to analyze the affective traits that affect mathematics achievement through Structural Equation Modeling (SEM) as a traditional regression model and Multivariate Adaptive Regression Splines (MARS), as one of the data mining methods. Structural Equation Modeling, one of the regression-based methods, is quite popular for…

This study examined the impact of the levels of fidelity of teacher implementation of a research-based middle school mathematics program, implemented systemically across a district, on student achievement benchmarks. By examining the systemic implementation based on the level of fidelity to the written curriculum, this quantitative study sought to…

This paper targets patterns of expressed emotional directions towards mathematics. By using TIMSS data and recoding two of the instruments, we compared responses from the same student cohort in Grade 4 (11 years old) and Grade 8 (15 years old) in Sweden. Two hypotheses were tested: negative emotions including negative motivations increase with…

Region 14 Comprehensive Center and the Arkansas Department of Education (ADE) are collaboratively implementing projects to address high leverage problems such as student access to effective educators, supporting schools serving specific student populations, and building school district capacity to design school models aligned to parent choice.…

In March 2020, the National Center for Special Education Research (NCSER) virtually convened a group of experts to discuss gaps in research on eighth grade mathematics for students with disabilities (SWD) that could be addressed with the NAEP process data and data science techniques for this research. Invited experts also provided recommendations…

The purpose of this action research was to evaluate the impact of writing prompts and graphic organizers on Mona school's 7th and 8th grade students' mathematical academic achievement and their attitudes towards the authentic application of mathematics. Two research questions guided the study: (1) How and to what extent, do writing prompts and…

The relationship between students' attitudes toward mathematics and mathematics achievement has garnered tremendous attention from researchers. However, there is a degree of inconsistency in the findings regarding this relationship. Therefore, this study aimed to identify the profiles of students' attitudes toward mathematics and examine their…

In TIMSS 2015, while two-thirds of students in grade 4 reported feeling very safe at school, by grade 8, less than half of the students surveyed reported feeling a high level of safety. Overall, girls were more likely to report feeling safe than boys. For both genders, feeling safe at school seemed to be positively related to academic achievement…

Trends in International Mathematics and Science Study (TIMSS) data reveal that setting high standards for the overall mathematics curriculum and ensuring teachers adhere to these standards may not necessarily lead to better learning outcomes for students. There are significant gaps between the intended and implemented grade 8 mathematics curricula…

Although Montessori is the most common unconventional education model, no multi-state study has compared standardized test proficiency of Montessori schools with districts. Here we report on this for the 10 states/regions with the most public Montessori schools (n = 195). In 3rd grade, Montessori schools were less proficient in math but more…

In this study, the effects of some student (e.g., gender, bullying, etc.) and school variables (e.g., emphasis on academic achievement, clarity of teaching, etc.) on the TIMSS 2015 science and mathematics achievement of eighth grade students in Türkiye were examined by controlling for the socioeconomic status of the students at the student and…

Breakthrough Collaborative operates as two dozen community-based affiliates supported by a national office. Traditionally, the Breakthrough model has consisted of two components: (1) a summer enrichment program that provides academic and social-emotional learning support to students; and (2) out-of-school-time tutoring and enrichment during the…

Over the years, the nation's large urban school districts have consistently learned from the progress of their peer districts across the country. Great City School districts that have embraced the challenge of educating America's urban children have recognized the value of benchmarking their performance and growth against the progress of others.…
