This dissertation in practice explores the intersection of computer science education, specifically computational thinking and programming, with mathematics achievement among 15- year-old students in selected English-speaking countries. The research addresses a gap in understanding whether skills developed through computer science can positively…

Motivated by a curriculum privileging number-based strategies but national tests highlighting students' reliance on standard algorithms, this study analyses 2,216 Danish Grade 3, 6 and 8 students' solutions to various multidigit arithmetic tasks, each designed to elicit shortcut strategies, against background variables including sex, ethnicity and…

Rurality is an identified point of disadvantage in measures such as the Index of Community Socio-Educational Advantage (ICSEA) and school resourcing models. However, socioeconomic disadvantage is commonly used as an explanation for lower average student achievement in rural locations. Thus, policies are often directed towards reducing disadvantage…

There is a problematic but widespread perception that we do mathematics with our minds, and sport and Physical Education (PE) with our bodies. Strong identification with sport and PE could therefore pose a barrier to mathematics learning. I explore this troubling possibility using data from a mixed-methods study of 450 Year Nine students (age…

Using the nationally representative sample from the United States in the 2012 Programme for International Student Assessment (N = 7,429 students from 240 schools), I examined the relationship between teacher instructional practices and student mathematics achievement. To account for the multilevel structure of the data with students nested within…

This paper provides empirical evidence on students' achievements determinants in Sub-Saharan Africa based on a sample of 26602 students from the ten countries that participated in the PASEC 2014 assessment. By using a two-level hierarchical linear model, I find that learning inequalities are primarily explained by differences in schools'…

Continuing efforts have been made in the United States (US) to examine the role of schooling in alleviating the ethnic/racial inequalities in student performance. Using the US data from the 2012 Programme for International Student Assessment (PISA), this study examines the between-school and within-school racial/ethnic differences in opportunities…

There is evidence of the impact of school segregation on students' academic achievement, but it is debated whether the extent of this impact is dependent on students' socioeconomic status, or on their native or non-native condition. This research addresses the problem in Spain, seeking to determine how immigrant and socioeconomic segregation…

School closures induced by the COVID-19 pandemic led to concerns about student learning. This paper evaluates the effect of school closures on student learning in Uzbekistan, using a unique dataset that allows assessing change in learning over time. The findings show that test scores in math for grade 5 students improved over time by 0.29 standard…

This volume of PISA examines the readiness of students to engage with learning strategies, to be motivated to learn and to be confident in their abilities and in their capacity to improve their skills and knowledge. Countries like Korea have reduced mathematics anxiety, Portugal excels in critical thinking, and more low-performing students in…

Today's economy demands higher order thinking skills (HOTS), and the public education system has a critical role in supporting students' acquisition of HOTS. Yet, numerous studies documented inequity in access to higher quality instruction that promotes HOTS, which could result in wide test score gaps in HOTS. In this study, I examined test score…

The impact of self-fulfilling prophecy in education, and of attainment grouping on pupil self-perception, remain topics of longstanding debate, with important consequences for social in/justice. Focusing on self-confidence, this article draws on survey responses from 9,059 12-13 year olds who were tracked by subject ('setting'). They provided…

This investigation focuses upon the nation of Finland. Described by its Ministry of Foreign Affairs ("This is Finland", n.d.) as a parliamentary democracy, Finland is a free-market economy with a young but progressive history. While the nation's scores on the 2015 triennial PISA continue to indicate above average performance on all three…

Building on the experience of working with middle-income countries in PISA since 2000, and in an effort to respond to the emerging demand for PISA to cater to a wider range of countries, the OECD launched the PISA for Development (PISA-D) initiative in 2014. This one-off pilot project, spanning six years, aims to make the assessment more…

Has the gap in average standardized test scores between students from high- and low-income families widened, narrowed, or remained stable over the last 3 decades? The question is important both because the achievement gap is measure of how (un)equally educational opportunities are distributed in the US, and because the disparity in educational…
