Younger generations have grown up with the Internet. Far from being a purely information search
engine, the Internet has become fully integrated into the way children live and learn today. It has
changed the way children interact with each other and carry out their daily tasks. In this sense and
given that children spend more and more time playing video games and on social networks, we
have tried to analyse the impact that daily Internet use may have on 6th grade primary school
students’ academic performance in Spain. To do so, we have used interval multiobjective
programming, which allows us to identify usage patterns and students' traits that maximise their
academic performance. Our results show that while daily use of social networks impairs academic
performance, using the Internet to listen to music or search for information on other topics of
interest helps to maximise students’ academic achievement.
