PurposeThe purpose of this article is to investigate factors related to the time students spent on remote activities during the coronavirus (COVID-19) pandemic in 2020. Specifically, it analyzes whether the school’s relationship with the family and the guardians’ support are associated with longer study times for children and youth.Design/methodology/approachThis was performed using an ordered logit model on data from two waves of the survey Remote Education in the Perspective of Students and Their Families (PENP) with a nationally and regionally representative sample of Brazilian public school students.FindingsResults show the importance of contact between the school and the family and, to a greater extent, the direct support of parents or guardians.
