The ability to interpret graphs is highly important in modern society, but has proven to be a challenge for many people. In this paper, two teaching methods were used to remediate one specific misinterpretation: the area misinterpretation of box plots. First, we used refutational text to explicitly state and invalidate the area misinterpretation…

This study uses the PIAAC data to examine the relationships between education system characteristics (e.g. early tracking and vocational education orientation) and distributions of adult numeracy skills. It also investigates the effects of postponing the tracking age and easing university access for students on a vocational track on the average…

This annual report shows how fee and support systems (including grants and loans) work in higher education in Europe. It provides both a comparative overview of fees and financial support available to full-time students in 2016/17, and also includes individual country sheets outlining the main elements of national systems. In particular, the…

Recent studies have shown that the interpretation of graphs is not always easy for students. In order to reason properly about distributions of data, however, one needs to be able to interpret graphical representations of these distributions correctly. In this study, we used Tversky's principles for the design of graphs to explain how 125…

Data distributions can be represented using different external representations, such as histograms and boxplots. Although the role of external representations has been extensively studied in mathematics, this is less the case in statistics. This study helps to fill this gap by systematically varying the representation that accompanies a task…

This first "OECD Skills Outlook" presents the initial results of the Survey of Adult Skills (PIAAC), which evaluates the skills of adults in 22 OECD member countries and two partner countries. The PIAAC survey was designed to provide insights into the availability of some key skills and how they are used at work and at home through the…

Direct provision of public services can alter the balance of resources across income groups. We focus on the issues arising when taking account of the impact of publicly provided education services across the income distribution. We combine OECD information on spending per student in particular levels of the education system with micro data from…

This report examines how immigrant students performed, mainly in mathematics and reading, but also in science and problem-solving skills in the PISA 2003 assessment, both in comparison with native students in their adopted country and relative to other students across all countries covered in the report (the "case countries"). In…
