It is a big problem to change seats.
Which position is the best light source in the classroom? Which position is the "Golden Seat"? It can be said that "there is a treasure in the house, breaking my heart" - every parent wants their child to have a good seat, good seat means good vision.
However, what is the standard for a good seat? - "My child's attention is not concentrated, can the seat be arranged in the middle?" "My child is nearsighted and wants to sit in the middle." "My child is a little squint, arrange a middle seat." ...". I believe that teachers have been asked more or less by parents, so it is inevitable that confusion will be arranged.
To be fair, many schools adopt a method of rotating seats on a regular basis. Regular rotation of seats is based on the actual situation of the class, determine the law of seat rotation (usually front and rear, left and right), adhere to weekly or weekly adjustments, in accordance with the law in turn.
Regular rotation of seats to protect students' eyesight is a talk of ribs?
Regularly rotating seats really solves the fair enjoyment of "golden seats" for all students? The new problem has come out again. Some parents have found a teacher, saying that there will be a short seat sitting behind the wheel, and the tall man sitting in front and blocking the blackboard. Affect learning. Then, if you regularly rotate your seat, is it a way to cure your symptoms?
At present, 6 ç› fluorescent tubes are installed in the general classroom, and 9 ç› is installed in the classroom with large area. Therefore, the position directly below the luminaire is sufficient. However, it is close to the wall, and even more in the back of the classroom. The light is seriously insufficient. It is very difficult to attend classes, especially when reading books at night. Regular rotation of seats in this classroom lighting environment is equivalent to allowing each child to avoid learning in a situation where the lighting is severely deficient, that is, to prevent each child from avoiding the danger of myopia. In contrast, not only is it fair but it is harmful to everyone.
I believe that many parents consider the choice of children's seats as "good location, good light, good for vision." In fact, if a lighting and lighting technical indicators meet the requirements of national standards, the light seen in each position will not increase the burden on the eyes. In such a classroom, some are lighting on both sides, some are single-side lighting, the light is strong and weak, and regular rotation of seats can really help protect the vision of all students. Only when the classroom meets the lighting standards, can the regular rotation of the seats not become a ribbed talk, and can also solve the problems of parents and teachers.
Rieter has a good light, so that the window of the soul is no longer dim!
Nowadays, the classroom lighting in many schools is dim or obsessed with “brightnessâ€. In fact, too dark and too bright lighting, glare caused by light can easily lead to eye fatigue, resulting in poor eyesight. Therefore, by building a healthy classroom lighting environment, the classroom has a scientific and reasonable distribution of lighting, which is often the most basic and effective way to protect students' vision. In actual situations, many factors such as the orientation of each classroom and the direction of lighting are different. Therefore, it is necessary to adapt the lighting environment to each classroom according to the actual situation.
According to the national compulsory standard “Classroom lighting and lighting standards for primary and secondary schoolsâ€, the average illuminance on the desk of the classroom should not be lower than 300lx, the uniformity should not be lower than 0.7, and the classroom blackboard should be provided with local illumination, which maintains the average illumination. Should be less than 500lx, the uniformity should not be less than 0.8.
In order to build a healthy classroom lighting environment, in addition to ensuring the illumination of classroom desks and blackboards, Rieter Education Lighting also proposes six indicators of full eye protection to provide a healthy light environment for schools. Lidaxin's six major indicators include illuminance, glare, stroboscopic light, color rendering index, color temperature, and blue light. From then on, the six core parameters will be upgraded, and the healthy classroom lighting environment will be built to solve the problem of insufficient lighting in the classroom. . Only on this basis can we solve the problem from the source and in essence, improve and enhance the visual acuity of young people, and let the flower and soul window of the motherland not be dim and “grayâ€.
