„Evidence from the 2018 PISA study indicates that when comparing 15-year-old students with similar characteristics in terms of socio-economic background, gender, age, immigration status and type of school attended, youngsters who developed stronger attitudes towards learning performed significantly better in reading, mathematics and science than those with weaker attitudes. […] Students’ enjoyment of reading, motivation to master tasks and self-efficacy in particular were highly associated with achievement.“
