Er is een nieuwe PISA in Focus en de eerste, euh, focus, ligt op ongelijkheid en hoe deze evolueerde over de verschillende PISA-rondes heen. Deze grafiek maakt alvast veel duidelijk:
Wat zijn de belangrijkst vaststellingen over de tijd heen:
Between 2006 and 2015, equity in education, measured by how much variation in performance is explained by students’ socio-economic status, improved in 11 PISA- participating countries and economies, and on average across all OECD countries.
The United States stands out as the country where, between 2006 and 2015, the impact of a student’s socio-economic status on his or her performance in school weakened the most, and where the likelihood that disadvantaged students perform at high levels increased the most.
No country or economy improved both performance in science and equity between 2006 and 2015, but mean achievement remained stable in nine countries where socio-economic status became a weaker determinant of student performance.
Het is belangrijk volgens de OESO te beseffen dat meer gelijke kansen niet ten koste hoeft te gaan van betere prestaties
Equity in education is also a matter of design and, as such, should become a core objective of any strategy to improve an education system. As socio-economic status becomes a weaker determinant of student performance over time, student resiliency tends to increase, and the proportion of low-performing students – who often come from disadvantaged backgrounds – tends to shrink. This suggests that policies aimed at helping disadvantaged students thrive academically should go hand-in-hand with policies that target low achievers.
