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

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.

The class is chaotic and not uniform. The height of the benches can be flexibly adjusted according to the height of the students, reflecting the concept of student-centered and personalized education. During the term term, the height of the benches and chairs should be adjusted individually to ensure that each child has a table and chair that matches their height.

Use the tallest chair possible. After that, place a foot pad on your feet, keeping your thighs and calves vertical. When the table or chair does not match its height, it is one of the factors that contribute to myopia in children.

Currently, most benches and chairs have automatic height adjustment. However, the class layout in developed countries in Europe and the United States is rarely uniform. Some are located in different regions, while others are beautiful due to their location.

The height of the desk and chair is flexibly adjusted according to the height of the student, which reflects the height of the student. If the height of the benches used for writing matches their height is one of the factors for myopia in children, then when the tasks of the same class are too short, a cushion should be placed on the table or chair.

What you should pay attention to is setting up lights, benches, and chairs in your classroom to reduce the risk of myopia. The distance between the benches should be increased. The height of benches and chairs should be adjusted individually every six months to protect children's eyesight and prevent myopia.

The issue of the height of the bench resonated with netizens. How do I adjust the height of the bench? Children are growing and developing, and their height changes from year to year.

If adjusted, the student's sitting posture will be non-standard, resulting in curvature of the spine, hump, and tilt of the shoulders. The net distance between the end of the desk and the wall must not be less than.

In the new period, pay attention to increasing the distance between benches and chairs. The height of student benches and chairs is individually adjusted each semester. In Beijing, more than 40% of primary and secondary school students have never set the height of benches, which is inappropriate.

However, primary and secondary education in developed countries in Europe and the United States is rarely uniform. In addition to adjusting the height of the benches, the school also replaced the light fixtures to protect the eyes. At the same time, reduce the cost of learning.

Be sure to pay attention to the height of the desk, and then students should also develop a good sitting habit, and be sure to pay attention to the distance between their eyes and books when writing homework, so as to prevent myopia.

Try to choose the height of the desk between 80 cm and 90 cm, because this can play a good role and avoid serious effects on the child's body, or other injuries.

Adjust a centered position, preferably to a height of meters, is the most appropriate, so that the child will not be short-sighted when doing homework.

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.

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.

We can adjust the height of the desk according to our height, and we need to adjust our posture when we sit on a stool.

You can keep the height of the desk at the bottom of the blackboard consistent, so that you can prevent myopia, it is better for children's eyesight, and such desks are also particularly beautiful.

The height of the desk should be adjusted so that the distance between the plane and the child's eyes when sitting upright is more than 15cm, so as to effectively prevent myopia.

Introduction: Many people will find that myopia is gradually showing a trend of younger age, and there are more and more myopic people in the group of primary school students, which can't help but make people worry about their children's eye health. In the course of classroom learning, in fact, many school desks should be able to adjust the height freely.

After all, every child's body is different, and it is most comfortable to choose different heights to read a book. Classrooms are not uniform, so how can you adjust the height of your desks to prevent myopia?

In the previous school process, the height of the desks was the same height that could not be adjusted, which had different effects for students of different sizes. Some children are too tall or too short to write at their desks, which also leads to problems with their eyesight. However, there are many new types of desks that can be adjusted in height.

The choice of desk height should be kept 10 cm away from the student's eyes, and the teacher can adjust the height of the desk in the appropriate position to ensure that the student sits in a correct posture and does not bend over and hunch, so that the student can ensure the correct sitting posture and be able to read the words on the book clearly when writing and reading.

In fact, many areas have realized that the height of the desk in the classroom should not be uniform, but should be diversified according to the different regional characteristics and the different growth and development of students, so it is said that the height adjustment of desks and chairs in primary and secondary schools has been specially regulated, and the school is required to adjust the height of the desk once according to the height of the child in a semester, and it is best to make a personalized adjustment to the functional students, so as to prevent myopia for students. It is also included in the assessment index system.

The development of students should be individualized in terms of education and equipment, after all, every child is different. Only by respecting the differences in children's personalities can we truly help children grow up healthily, and the height of desks and chairs is actually one of the manifestations of this.
