This article examines the effects of education system types and characteristics on changes in the distributions of literacy and numeracy skills during the upper secondary phase of education and training. Whereas there is a substantial literature on system effects on skills during the primary and lower secondary phases of education, much less has…

International tests demonstrate that students' mathematics and reading skills vary widely across countries. I investigate whether a country's cultural characteristics are the fundamental cause of these differences, while family and school characteristics are the proximate causes. I find that while either cultural characteristics or family and…

Background: The recommendation from national documents and reports to promote inquiry-related science activities has not been supported by recent studies, which have found the overall frequency of inquiry activities to be negatively associated with student learning outcomes. This study was inspired by such conflicting reports and aimed to clarify…

The countries of the Eastern Partnership (EaP) -- an initiative between the Member States of the European Union and Eastern European and South Caucasus countries -- are navigating significant challenges while striving for sustainable economic growth and social cohesion. Education plays a crucial role in unlocking the potential of digitalisation…

Improving the proficiency in mathematical literacy is one of the efforts to improve the human resources quality. Its development describes the students' strengths and weaknesses to support the improvement. The research tried to describe the development of students' proficiency in mathematical literacy, based on the school level and the students'…

Socio-economically advantaged and disadvantaged students are not equally exposed to mathematics problems and concepts at school. Exposure to mathematics at school has an impact on performance, and disadvantaged students' relative lack of familiarity with mathematics partly explains their lower performance. Widening access to mathematics content…
