Recently, Changsha Lushan International Experimental Primary School announced that there will be six new changes in the upcoming new semester, mainly extending the break time to 15 minutes and starting classes at 9:20 am for first and second grade students. As soon as the news spread, it attracted social attention. The importance of sleep for primary and secondary school students who are in a critical period of growth and development is self-evident. Normally, elementary school students need 9 to 10 hours of sleep per day. Long term lack of sleep can lead to delayed growth and development, seriously affecting their height and physical fitness. Not only that, but it can also cause irreversible damage to children's learning and memory functions, manifested as a decline in memory, calculation ability, and thinking agility, lack of concentration, and easy deviation, which in turn has a negative impact on grades. So, some parents have to compress their children's breakfast time in order to give them more sleep. However, the comprehensive evaluation and monitoring of the quality of primary and secondary education in Zhejiang Province shows that having breakfast has a positive impact on students' learning, far exceeding the advantages of students participating in extracurricular tutoring, parents' educational level, or family income. Research has found that there is a significant difference in academic performance between students who eat breakfast every day and those who have irregular breakfasts. Students who eat breakfast more times a day per week have higher academic performance. A breakfast has such an incredible effect, and behind it lies profound scientific principles. Students who do not have breakfast lack sufficient nutrients in their blood to cope with their studies and are easily distracted, making breakfast the most important meal of the day. In other words, if you want to improve students' grades, instead of spending a lot of money on extracurricular training classes, it's better to prepare a delicious breakfast and deliver it to your child every day. Based on a profound understanding of the laws of education and teaching, as well as the laws of student growth, and with the call of knowledgeable individuals, various regions have been exploring the postponement of school enrollment. In this context, the measures taken by Changsha Lushan International Experimental Primary School are undoubtedly impressive. It is reported that in the current compulsory education stage in Changsha, primary schools start classes at 8:30 am and junior high schools start at 8:00 pm. Regarding the new measures of this primary school, relevant personnel from the Changsha Education Bureau suggest that they can be tested first and gradually improved. Students can indeed sleep a little longer, but some netizens question whether this will increase the burden on parents. Therefore, it is necessary to conduct sufficient investigation and research to address the potential issues that may arise during the postponement of school enrollment, and to provide practical and feasible solutions. In order to address the concerns of parents, the school has made sufficient preparations and introduced corresponding arrangements. For example, setting up a "green channel" for some children who cannot postpone their school start, allowing them to enter the school early and be managed by the on duty teacher; By adjusting the schedule, the classroom teaching time can be adjusted from the original 40 minutes to 35 minutes. By reducing ineffective teaching behaviors in the classroom and improving teaching efficiency, the reduction in time can be compensated for, ensuring that the quality of teaching will not be affected by the reduction in learning time. Lack of sleep among primary and secondary school students involves various issues, which are difficult to easily resolve through a single requirement or regulation. If only the school arrival time is postponed without solving the problem of students' "burning the midnight oil", the child will still not be able to wake up. If the homework assigned by the school is controlled, but parents start a "no makeup on campus, no makeup outside the school" campaign, it will also be of no help. In view of this, while vigorously promoting the "double reduction" policy, it is also necessary to comprehensively implement policies and systems to effectively grasp the "bull's nose" of students' heavy burden, remove the "roadblocks" that affect children's sleep, and enable children to have a good night's sleep. Implementing new measures requires a process. To encourage children to sleep longer, it's not just about postponing class times, but also about effectively reducing students' academic burden. It's a long and arduous task. However, the attempts and explorations to give children a good night's sleep have at least laid a good foundation for subsequent comprehensive management, and similar measures are more beneficial.
