Education is an equally important issue in the development of the country, especially the education of young people, and it is the top priority of the reform of the national education sector.The popularization of nine-year compulsory education has greatly improved the overall quality of the people and has also enabled students in primary and secondary schools to have the right and obligation to receive education. After the end of nine years of compulsory education, students have to face a variety of large-scale examinations, only in the important assessment of excellent results, students can successfully enter the ideal school, if the student's grades do not meet the standard, will also be ruthlessly eliminated, facing the embarrassing situation of diversion.
In today's era of involution education, students' learning pressure is becoming more and more heavy, under the excessive arrangement of parents and teachers, students have to study in school during the day, and enter a variety of cram schools and training classes at night, and the young age bears a greater burden, which also leads to many primary and secondary schools in order to improve the admission rate of students, will require students to come to school in advance to participate in the morning self-study course or organize evening self-study courses at will.
Students in primary and secondary schools are in a critical period of physical development, not only need rich nutrition, but also need to maintain adequate sleep, long-term lack of sleep quality will affect the health of students, but also induce various chronic diseases, for primary and secondary school students' sleep problems, the education department will have to readjust their class time, students are very happy after listening.
The class time of primary and secondary schools may have to be adjusted, and the students are very happy, and the teacher can't sit still after listening to it
In order to increase the admission rate and improve the learning efficiency of students, many primary and secondary schools require primary and secondary school students to come to school in advance to participate in early self-study courses, which helps to improve students' learning efficiency, but also increases students' physical burden and mental exhaustion.
With the implementation of the new policy: in the future, primary school students will not start classes earlier than the morning8:20 a.m., morning classes for middle school students must be no earlier than 8 a.m.
In addition, the education department also strictly stipulates that primary and secondary schools around the country shall not arbitrarily organize morning self-study courses, nor shall they delay the release time of students, in addition to the implementation of after-school 5 + 2 teaching mode, students shall not be required to participate in evening self-study courses at will, primary and secondary school students should be given sufficient rest and sleep time, and students who stay in school at noon and do not go home should also have a lunch break of at least 30 45 minutes under the management of teachers.
When assigning homework to students, primary and secondary school teachers should also try to simplify the total time for primary school students to complete homework should not exceed 60 minutes. The total time for middle school students to complete homework should not exceed 90 minutes, and students in first and second grades should not be assigned homework, and the 2-month Dynamic Incentive Program gives students a sufficient time to rest and relax. 
In order to alleviate the learning pressure of students, the education department officially implemented the double reduction policy, the main purpose of the implementation of this policy is also to allow students to learn easily and happily, play a relatively relaxed learning atmosphere for students, so that students can learn new knowledge in entertainment, healthy and strong growth, for this reason parents must pay attention to the physical and mental health of students while paying attention to students' performance.
The policy of adjusting the class time for primary and secondary school students is good news for students, but it makes many teachers feel pressured, which requires teachers to develop a better teaching plan in order to complete the corresponding teaching courses within the specified time, improve students' grades, and let the students in the class achieve better scores in large-scale examinations, which is also of great help to the evaluation of personal titles.
Students in primary and secondary schools should ensure at least 8 10 hours of sleep every day, which is also in line with physiological needs, and I hope that schools and parents can pay more attention to students' health problems, and do not lose big because of small things.
