The classroom is not uniform, how to adjust the height of the desk to prevent myopia?

During the "Two Sessions" in Beijing. Liu Yan, a member of the Beijing Municipal Committee of the Chinese People's Political Consultative Conference and a professor at the Beijing Dance Academy, has been an "old member" of many meetings. She told the "Beijing News" reporter that she put forward three suggestions this year, one is to adjust the height of desks and chairs for primary and secondary school students.

She suggested that primary and secondary schools in Beijing should quickly adjust the height of desks and chairs to suit the height of students.

<> Professor Liu's suggestion is based on a report by the Beijing Center for Disease Control and Prevention. The relationship between reporting, reading, and writing steps and the height of myopic children, while the number of primary and secondary school students in Beijing is extremely inappropriately adjusted by four steps, so that myopic students sit very loosely, etc. , which has a significant impact on associated factors, as well as growth failure.

In fact, depending on the current design of tables and chairs (most of which have handles that automatically adjust the height), there is no additional cost to adjust the height of the table and chair. But why don't so many schools do such a simple job? This is not only because of the lack of unified normative requirements, but also because many schools do not pay enough attention to the healthy growth of students, and there is a deviation in the understanding of "classroom beauty".

According to statistics, the comprehensive detection rate of poor eyesight among primary and secondary school students in Beijing is the highest. There are many factors that affect students' eyesight, among which the poor classroom environment is also an important reason, and this part of the factors can be improved as soon as possible, which is much easier than reducing the burden on students. The height of the desks and chairs of primary and secondary school students has never been adjusted, and it is very likely that the school is not aware of this and is not aware of the change in the height of the child, therefore, the height of the desks and chairs has been inappropriate, but it has not been adjusted.

In addition, some primary and secondary schools in China also have the habit of managing students in a unified manner, taking regularity as the aesthetic standard. As a result, there is a reluctance to adjust the desks and chairs to accommodate the height of the students, for fear of affecting the aesthetics of the classroom.

Therefore, to solve the problem of the height of tables and chairs in primary and secondary schools, on the one hand, we can clarify the adaptation standards, requiring each school to adapt to the change of children's height once a semester. It's best to make individual adjustments for different students. The adjustment of school chairs, tables and chairs can be included in the school index evaluation system to prevent students from becoming myopic and establish a reporting system.

On the other hand, schools should establish a student-centered personalized education concept, focusing on cultivating students' personalities, cultivating students' interests, encouraging students to think, participate, and scientifically arrange classrooms. Create a diverse classroom culture.

Adjust the height of the desk according to the child's height, find the height of the table and the height of the seat that are suitable for the child's height, and ask the child to straighten his back with his elbows 3 to 4 cm under the table.

First of all, when adjusting the height, it must be humane, the height must be adjusted according to the height of the child, and the height of the student's eyes and restraint must be kept at 10 cm.

The first row can be the lowest, the last row is the highest, and the middle position is higher than the first floor, so that students can be less short-sighted.

Everyone now has higher requirements for children's things, and I also hope to buy good desks, which are practical and environmentally friendly, and children can use them safely and healthily and happily. Let me tell you what I think. Material:

Now more plastic is used, as well as wood, the advantage of plastic is that it is malleable, and it can be designed with a variety of shapes and colors, children prefer but the practicality is not as good as wood, and parents will be more inclined to wood. If you are wood, you can look at the grade of the desk with solid wood or composite board, but one thing to pay attention to is the paint problem, formaldehyde is definitely not good for children. Design Structure:

Because the child is still growing up so the height changes greatly, the height of the desk and the table top should be designed to be adjusted to meet the needs of different babies, and now many children's desks will be designed with an inclined plane is also to allow children to not overbend the spine when writing homework.

The desk also needs to have a certain storage function, you need to design a small bookshelf to put the books you read daily, put a few small drawers, you can put some learning tools and the like. Another is that the desk is generally equipped with a desk lamp, and it is necessary to design the position of the desk lamp, and if it is placed directly on the desktop, it is necessary to design the inlet of the power supply to facilitate power. Style design:

China's Ministry of Health has issued a national standard for the hygiene of school desks and chairs, which determines the height standards for desks and chairs used by nine types of students of different heights. For example, if a student is under 119 cm tall, the height of the desk should be 52 cm, the height of the empty space under the desk should be 40 cm, and the height of the chair should be 29 cm.

Students who are between 143 and 175 cm tall should be 67 cm tall on desks, 55 cm in the open space under the desks and 38 cm in chairs. Moreover, according to the regulations, the form of desks and chairs used in primary and secondary schools can be optional, but the main dimensions of the table height, the height of the empty area under the desk and the height of the chair must meet the national standards. There's no grade-level like you're talking about, and a lot of schools don't meet the standards right now.

For saying that the classroom is not uniform, it is beautiful, and I want to adjust the height of the desk to prevent myopia. First of all, the teacher should adjust according to the student's own height and the degree of myopia of the eyes.

We must use scientific standards to adjust the height of the desk, and the school must adjust the height of the desk according to the height of the child every semester, which will prevent myopia.

If you want to adjust the height of the desk to prevent myopia, I think it is better to set it according to the height of the student, and it can play a role in preventing myopia.

The recommendation is based on a report published by the Beijing Center for Disease Control and Prevention. According to the report, whether the height of the desks and chairs used by students to read and write is in line with their height is one of the factors for children's myopia. Data shows that more than 40% of primary and secondary school students in Beijing have never adjusted the height of their desks and chairs.

Improper desks and chairs can have a great impact on myopia-related factors such as sitting posture and visual distance, resulting in poor vision.

It can be said that Professor Liu took the opportunity of the "two sessions" in Beijing to upgrade the previous CDC proposal to a proposal, hoping to attract the attention of relevant departments. But why can't many schools do such a simple job? This is not only because of the lack of unified standard requirements, but also because many schools do not pay enough attention to the healthy growth of students, and there is a deviation in the understanding of "classroom beauty".

According to statistics, the total physical detection rate of poor eyesight among primary and secondary school students in Beijing is at a high level. There are many factors that affect students' eyesight, among which poor classroom environment is also an important reason, and these factors can be improved as soon as possible - much easier than reducing the burden on students. Like the height adjustment of tables and chairs, it can be said that it is very easy, but it is not done well, and it is worth reflecting on.

More than 40% of primary and secondary school students have never adjusted the height of their desks and chairs. It is possible that the school is not aware of the change in the child's height, making the height of the desk and chair inappropriate but not adjusted.

In addition, some primary and secondary schools in China are accustomed to the unified management of students, and uniformity is the standard of "beauty". So I don't want to adjust the desks and chairs according to the height of the students, for fear of affecting the aesthetics of the classroom.

This is a deeper issue of educating people. Most primary and secondary school teachers in China still line up around the podium, and students sit in rows. This is a classroom-centered, teacher-centered, and textbook-centered teaching model.

However, the layout of primary and secondary school teachers in developed countries in Europe and the United States is rarely uniform, some are arranged in different regions, and some are free to adjust desks and chairs according to different class tasks. The diversified layout of the classrooms also reflects the characteristics of the school's personalized teaching.

Therefore, for the height adjustment of tables and chairs in primary and secondary schools, on the one hand, it can be clearly stipulated that each school is required to adjust it once a semester according to the change of the child's height, and it is best to make personalized adjustments for different students. The adjustment of school tables and chairs can be included in the school's evaluation index system for the prevention of students' myopia, and a reporting system should be established.

On the other hand, schools should have the concept of individualized education, be student-centered, focus on promoting the development of students' personalities and interests, encourage students to think and participate, arrange classes scientifically, and create a diversified classroom culture.

The height of the desk should be kept at 10 cm from the student's eyes to ensure that the student's sitting posture is not overturned, and the size of the desk should be noted.

The height of the desk can be made at the most appropriate angle with the average height of the student, and such an angle can also adjust the sitting posture and prevent myopia.

First of all, you should match the height of the table and chair with your height, and you should also pay attention to your sitting posture when reading, and you should also keep a certain distance from the table and chair when writing, and you should also develop a good way of using your eyes, do not use your eyes excessively.

Classrooms are not uniform, and you can choose to prevent myopia by adjusting the height of the desks, for example, you can adjust the height of the desks to about one meter. Some children are taller, so you can help these children choose some higher desks, so that they can keep a proper posture when writing homework. Therefore, not the whole class of desks should be guaranteed to be at the same height, and pursuing the same height can easily lead to some problems for children.

In addition, the height of the chairs in the class can also be adjusted appropriately, and tables of different heights can be matched with chairs of different heights. In such a situation, the child will be able to learn better in class, and some teachers like to put the short students in the front and the tall students in the back when arranging the seats. Because the teacher is worried that the short students will not be able to see the blackboard in front of them, in fact, this arrangement is not particularly reasonable, because there are many tall people who are delayed in this way.

Therefore, the teacher can choose to adjust the height of the desks and chairs in the class, so that the child can learn in a better way. For example, if the child is very tall, then the teacher can also choose to make the child's chair slightly lower, so that the child will not block the person behind him. If it is the turn of the shorter child to sit in the back, you can choose to assign a taller chair to the shorter child so that the child will not be blocked by the person in front of him.

Therefore, the desks in the class do not need to be uniform, and the chairs can also be changed accordingly, these adjustments are very flexible, and the teacher needs to arrange them according to the characteristics of the students, so that it is okay. Therefore, the teacher can choose to put more effort into this aspect, so that the guidance of the students will be better, and the help for the children will be stronger.

First of all, the layout of the classroom should be diversified, and secondly, it should reflect personalized teaching, and then it can be freely adjusted according to different courses, so as to prevent myopia.

First, the layout of the classroom should be diversified, secondly, personalized teaching, and then freely adjusted according to different courses to prevent myopia.

To choose the right height according to the age of the child and the height of the child, be sure to adjust the height of the seat in a timely manner, and adjust the angle well.

Start by asking your child to straighten his back and keep his eyes one foot away from the table. This will allow you to adjust the height of the desktop.

At present, everyone's food regulations for children are very high, and the desks are also looking forward to buying better, looking forward to using them for environmental protection, and children are happy to use them for health and safety. Let me share my opinion. Material:

Nowadays, more plastic is used, there are also wood, the benefit of plastic is that it is malleable, can be designed and coded a variety of shades, children are very fond of but the applicability is not as good as wood, parents will be more inclined to wood.

The wood has to be solid wood or sandwich panel to look at the desk level, but one thing to pay attention to is the paint problem, indoor formaldehyde is definitely not good for children. Design structure: because the child is still in the development period, so the height of the desk has changed, the height of the desk in the design situation also needs to be designed to be able to adjust to meet the requirements of different babies, and now many baby's desks will be designed as a ramp is also because the child is not easy to bend the spine too much in the case of homework.

The desk also needs to have a certain role in placing things, and a small bookcase must be designed to be placed in the books that are read daily, and a number of small drawer cabinets can be placed to put some teaching tools and the like. There is also a desk is generally equipped with a small desk lamp, must be designed to place the small desk lamp part, if immediately put on the desktop to design the switch power supply of the three-phase five-wire port, convenient plug-in. Style design:

Children love to be lively and cute, you can make the book designed to look like an animal, then children must love it, and the color also needs to be bright colors, which is very easy to lead to children's hobbies.

In China, the Ministry of Health of the People's Republic of China has announced the national industry standard for the environmental sanitation of desks and chairs for students in colleges and universities, and clarified the height specifications for desks, chairs and benches used by nine types of students of different heights. For example, if the student is less than 119 cm, the height of the desk and chair should be 52 cm, the height of the empty area under the table should be 40 cm, and the height of the chair should be 29 cm.

Students who are between 143 and 175 cm tall should be 67 cm tall with desks and chairs, 55 cm from the empty area under the desk, and 38 cm from the top of the chairs. And according to the requirements, the types of student desks and chairs used in primary and secondary schools can be selected at will, but the key specifications of table height, height of the empty area under the table and height of the chair must meet the national industry standards. There's no class-based as you say, and many colleges and universities don't meet the rules these days.
