Student achievement varies widely across developed countries, but the source of these differences is not well understood. One obvious candidate, and a major focus of research and policy discussions both in the United States and abroad, is teacher quality. Research and common sense tell that good teachers can have a tremendous impact on their…

The Australian Council for Educational Research (ACER) is one of the world's leading educational research centres. Since it was established in 1930, ACER has built a strong reputation as a provider of reliable support and expertise to education policymakers and professional practitioners. Each year, ACER is involved in a large number of research…

Classmates can influence a student's academic achievement through immediate interactions (e.g., academic help, positive attitudes toward reading) or by sharing tangible or intangible family resources (books, stories of foreign travel). Multilevel analysis of 141,019 fourth-grade students' reading achievements in 33 countries showed that…

Does the government control of school systems facilitate equality in school quality? Whether centralized or localized control produces more equality depends not only on what "could" happen in principle, but also on what does happen in practice. We use the Programme for International Student Assessment (PISA) database to examine the…

The Program for International Student Assessment (PISA) is a system of international assessments that allows countries to compare outcomes of learning as students near the end of compulsory schooling. PISA core assessments measure the performance of 15-year-old students in mathematics, science, and reading literacy every 3 years. Coordinated by…

Instructional written materials play important roles as teachers' agents in effective teaching practices. Worksheets are one of the most frequently used materials. In this exploratory study, the relationships between worksheet usage and science achievement in 32 countries were examined through the use of TIMSS and PIRLS data and multiple…

Analysis of both cross-sectional and longitudinal data from five studies on the academic achievement and cognitive abilities of the top 10% and the most average 10% of students in grades 1, 5, and 11 found high-ability Asian students outperformed high-ability U.S. students in mathematics but not in reading.

There is considerable debate about the relative importance of family versus school factors in producing academic and nonacademic student outcomes, and whether and how their impacts vary across different student groups. In addition to critically reviewing and synthesizing earlier work, this study extends the literature by (a) using the ECLS-K, a…

Utilizing data on approximately 16,000 children from the Early Childhood Longitudinal Survey-Kindergarten Cohort and a rich set of mediating factors on 16 immigrant groups, this paper examined the associations between children's immigrant generation status and their academic performance. The changes in academic achievements during kindergarten and…
