This dissertation examines a vital catalyst in the globalization of education: international assessments--that involve testing and rankings--of student achievement in academic subjects. Nearly all high-income countries participate in international assessments such as Trends in International Mathematics and Science Study (TIMSS), Progress in…

Test-based accountability as well as value-added asessments and much experimental and quasi-experimental research in education rely on achievement tests to measure student skills and knowledge. Yet, we know little regarding fundamental properties of these tests, an important example being the extent of measurement error and its implications for…

Indigenous Australians have been known to be disadvantaged in many ways although higher art and physical self-concepts have been reported with Indigenous samples. Given recent research demonstrating the reciprocal effects of achievement and self-concept in academic domains, Indigenous students may experience further disadvantages in both academic…

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…

We examined the degree to which child, family, and treatment variables predicted treatment outcomes for reading and math achievement and oppositional behavior in a sample of 135 young children (105 boys and 30 girls). All of the participants met "Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision"…

This meta-analysis summarizes research on the effects of a comprehensive, interactive web-based software (AXXX) on the development of reading competencies among kindergarteners and elementary students. Findings from seven randomized control trials and quasi-experimental studies undertaken in a variety of contexts across Canada, Australia and Kenya…

In the generative classroom, teachers provide well-designed learning environments that result in the combination, recombination, and reorganization of repertoires such that new untaught repertoires are likely to occur. One component that can contribute to such generativity is Precision Teaching (PT), a frequency building instructional…

This article presents findings of an efficacy trial examining the effect of a multitiered instruction and intervention model on first grade at-risk students' reading outcomes. Schools (N = 16) were randomly assigned to the treatment or control condition. In the fall of Grade 1, students were assigned to an instructional tier on the basis of…

We adapted and piloted Collaborative Strategic Reading-High School, a reading comprehension intervention, with three high school students with autism spectrum disorder to investigate its effects on their reading comprehension. Using a nonconcurrent, multiple-baseline design, participants with autism spectrum disorder were paired with a…

This study examines the effect of 30 min of small group explicit instruction on reading outcomes for first-grade Spanish-speaking English learners (ELs) at risk of reading difficulties. Participants were 78 ELs from seven schools who were receiving Spanish only, or Spanish and English, whole group reading instruction in first grade. Students were…

This policy profile on education in Hungary is part of the "Education Policy Outlook" series, which presents comparative analysis of education policies and reforms across the Organisation for Economic Co-operation and Development (OECD) countries. Building on the OECD's substantial comparative and sectorial policy knowledge base, the…

This groundbreaking study is the first ever to examine the achievement of high-performing students over time "at the individual level". It poses--and seeks to answer--this straightforward question: Do students who outscore their peers on standardized achievement tests remain at the top of the pack year after year? Put differently, how many "high…

Numerous studies have shown how elementary social studies instruction has been constrained or curtailed in states that do not test social studies as part of their mandated accountability system. South Carolina is a state that tests social studies as well as English, mathematics, and science in grades three through eight as part of its…
