Learing online requires students to do things that will have negitive effects on the students. Two effects are caused by students sitting for a long time. One is weak muscles and damaged eyesight.
Distance learning is hard because (point a) there is less in-person contact with teachers and other students, (point b) students have to manage themselves all the time, and (point c) students have more access to their phone and computer at any given time, which means more students choose to mess around instead of paying attention in school.
