Parents are generally dissatisfied with the amount of homework. Parents are generally dissatisfied with the amount of homework. “Homework” always has been present in the school education, these have contributed to reinforce the knowledge acquired in the school, motivating to learn study habits, developing responsibility and, building the commitment to our education. For approximately 15 years, schools have increased the amount of homework for children without thinking that children need to play a lot and, resting, which it caused the demotivation as well as conflict between parents and children and, parents and teachers. Due to the fact that parents had a different schedule, children did not finish their homework or they went to sleep too late. Nowadays, The OECD’s Pisa program, recommends no more than 4 hours of weekly homework in primary school is useful and, more hours is useless. Children will be tired before they start high school and, school failure will come. Consequently, schools have decreased the amount of homework. In my opinion, it will depend on how schools are organized and give children a better quality of teaching, as well as the willingness of parents to help. In conclusion, homework is necessary but not so much.
