This paper examines and builds on an earlier contribution to this journal focusing on private supplementary tutoring -- widely known as shadow education -- in Francophone West and Central Africa. Drawing on wider literature about research methods in this domain, it examines the basis for the numerical estimates presented in the original article…

Recent decades have witnessed a global expansion of private supplementary tutoring, known as shadow education--additional support in academic subjects that takes place outside of regular school hours. Using the data of 55 countries from the Programme for International Student Assessment (PISA) 2022, this study examines the association between…

Inequality in the shadow? Cross-national comparisons of the effects of additional instruction on math and science performance based on PISA 2018 data Background Many educational systems worldwide are experiencing a growing demand for shadow education, which often takes the form of outside-school educational activities such as private tutoring…

In many countries, out-of-school tutoring in academic subjects has become a widespread phenomenon that affects high proportions of students. Scholarly literature has considered various determinants of participation in such tutoring, but school quality has as yet been rather neglected. The aim of the study is to explore the relationship between the…

Science education as a part of STEM education is becoming important not only for the future success of the individual but also for the economic development of the nation. This study explores the global pattern of extended education and its impact on learning outcomes in the area of science. First, the study found substantial national differences…

While shadow education, organized learning activities outside formal school, has grown greatly around the world, the relationship between formal schooling and shadow education has not been well investigated. This study is therefore intended to empirically test whether formal education's structure (i.e. tracking) affects students' shadow education…

This study comes at an opportune moment for Japanese and U.S. educators, policymakers, and researchers given the trends of global policy and equity-based reform. Discussions of academic achievement in both societies allow us to examine accessibility in mathematics education in order to best prepare teachers to serve the needs of students.…

Considering the great impact the first PISA-results caused in Germany and Japan, this study seeks to provide an explanation for the continuous higher achievement rates of students in the PISA-winner country Japan compared to their German peers. Another great difference between the two participants that was detected in PISA is the correlation…

The aim of this study is to examine whether the expansion of higher education across countries is associated with the growth of shadow education as a function of families' efforts to ensure attainment of educational opportunities. To address this research objective, this study samples approximately 163,000 students, nested in 21 Organization for…

This study examines the relationship between opportunity-to-learn (OTL) at home and students' attainment of science proficiency. The data set used was the 2006 PISA science US national sample. Data mining was used to create patterns of association between home OTL variables and student attainment of science proficiency. It was found that students…

Kariya (2009) proposes a concept of learning competencies to understand how social reproduction occurs in the current context of Japanese society; he argues that students learning competencies are not equally distributed but shaped by their family background, a foundation of unequal socioeconomic inequality. While he contends that learning…
