„Students participating in PISA whose parents report ’spending time just talking to my child‘, ‚eating the main meal with my child around a table‘ or ‚discussing how well my child is doing at school‘ daily or nearly every day are between 22 % and 39 % more likely to report high levels of life satisfaction. ‚Spending time just talking‘ is the parental activity most frequently and most strongly associated with students’ satisfaction with life. […] Students whose parents report ’spending time just talking‘ are the equivalent of two-thirds of a school year ahead in science performance. Even after accounting for socio-economic status, these students are still one-third of a school year ahead.“
