School IS better then holidays. Holidays are boring, what can you do ? Parents have no time. Even if they do what can you do with them? Where school is way better because you get to see your friends. Don't you forget something sometime well it can happen with schoolwork in the holidays. So school is better then holidays!
Actually, I think holidays are better than school because of how much less is going on. Due to homework, exploratories, etc. school leads to terrible stress and hurt a person physically as much as mentally. Holidays allow for a student to relax, as well as prepare for school again so that the stress is less impactful.
Due to holidays teachers need to use a month or two to review what students learnt in the previous term or year. Which losses a lot of precious learning time! We can try very hard on a educational thing, then it's term break we don't practice as much so back at school we forget things that we need to learn again. If that happens then the student will lose confidence in their own learning and stop trying, that will lead to the student future's disaster and he or she shall not be successful!
How about concentration ? After a good long holiday children are still relaxed and not ready for learning, teachers always have problems with children that don't concentrate, more than normal after a holiday ! I'm almost sure that your child (children) have seen or heard teachers saying things like "your holiday is over, snap out of it" if they are at a primary school. Do you have time for children in the holidays? Even if you do I think they will like school more because you may stay at home with them, but most of parents don't play and teach their children at home. You may think that playing with them doesn't matter but having a good relationship with them help you get your child to learn thing that you want to learn. Thank you !
