Yes I think Saturday school should be required for failing students, but only if the students are seriously trying during the regular school hours and needs more help. If a student is failing classes because he or she shows no interest in the class then Saturday school would not change that.
Education should start at home, not at school on Saturday. Kids who fail in school often aren't getting enough attention at home from parents. School on a Saturday shouldn't be mandatory for kids failing their classes. A different approach to education is needed, not more classes. If a kid is failing, he or she needs to have someone take charge of their education in a different method.
I think that will not work because either they will not show up or they will do nothing when they are there. We are working with a different generation of students and youth. They are not willing to put in the work that students used to. They believe that everything will just be given to them instead.
Saturday is often reserved for children's participation in sports and extra curricular activities which promote better learning in the classroom.
Social interaction, free time and play are also essential to a child's learning and development.
99% of the time, people fail because they just don't care. Beating a dead horse doesn't make it more dead. If the students don't understand that good grades are a step towards a good future, than that's their fault! Why should the teachers have to work overtime just to get the same attitude from these kids that they normally do?
