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…

Breadth and depth of curriculum are important for success in science teaching and learning. Curriculum theorists recommend less breadth and more depth than overloaded, superficial science curricula. This study investigates breadth and depth in the official biology syllabi in the seventh to eighth or ninth years in four diverse jurisdictions,…

International Large-Scale Assessments (ILSAs) have had significant impact on education policy across the globe. But has interest in ILSAs now started to wane? This paper presents new evidence on this issue, exploring how the amount of attention three major ILSAs receive compares across countries, between studies and over time. Using information on…

In recent years, researchers have shifted from pathologizing Black youths, when investigating the Black-White achievement gap, to focusing on factors contributing to their resilience and success. A critical review was conducted of three widely cited asset-based theoretical frameworks that are used to examine African American students' academic…

The purpose of this nonexperimental quantitative research study was to explore and identify factors affecting the performance of elementary and secondary Title I schools in South Carolina. The study analyzed statistical significant differences in the overall performance of Title I schools over three years and analyzed other factors such as the…

This grounded theory study explores literacy achievement among male and female elementary school students. It focused on the perceived gap between genders and teachers' perspectives on narrowing this divide. Despite progress in education, educators still face ongoing challenges in literacy achievement disparities, where gender often plays a…

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…

Background: The existence of a multiplier, compositional or social context effect is debated extensively in the literature on school effectiveness and also relates to the wider issue of equity in educational outcomes. However, comparatively little attention has been given to whether or not the association between student achievement and school…

This research aims to analyze the relations from motivation to self-regulatory strategy on academic achievement in high school among academically higher-achieving students. Methods in autoregressive cross-lagged modeling by Mplus8.5 are used to evaluate 309 high school students with higher achievement in language or mathematics from the Korean…

This two-year study examined the impact of Spalding's The Writing Road to Reading literacy program on student achievement across grades K-5 in 14 Arizona schools. Using a quasi-experimental matched design, researchers compared 687 students from three Spalding schools with 1228 students from eleven comparison schools using Fundations. Data from…

Social skills are critical behaviors that enable students to effectively navigate their social lives. Further, social skills function as protective factors against emotional behavior concerns and enable strong academic growth. Social skills can be developed and improved via programs implemented in schools. Students identified as gifted have long…

The COVID-19 pandemic resulted in significant disruption in schooling worldwide. Global test score data is used to estimate learning losses by modeling the effect of school closures on achievement by predicting the deviation of the most recent results from a linear trend using data from all rounds of PISA. Mathematics scores declined an average of…

The ability to extract structural information from a drawing of a molecule is key to being successful in organic chemistry. One source of difficulty for novices in interpreting structures is that hydrogens bound to carbon are represented implicitly in the often-used line-angle structures. Other representations that explicitly show hydrogens, such…

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…

By the end of 2021, more than 168 million students across the globe had missed a year of face-to-face schooling due to the COVID-19 pandemic. In NSW, Australia, most students engaged in learning from home for eight weeks during 2020 and a further 14 weeks during 2021. This study provides robust empirical evidence on how two years of disruptions to…
