Whether you prefer homeschooling or your kid goes to school, his efficiency will certainly change. And there are several reasons for that:
– fluctuations of rhythms of life – both biologically based and acquired ones;
– relative complexity in studying certain subjects;
– children’s interest in classes (depending on the teachers’ skills or personal kids’ interest).
But sometimes hygiene conditions of study play a special role here. If your kid studies at home, the following tips will help your child learn easier and more effectively.
Lighting in the room
Poor room lighting makes it difficult for a child to percept information visually, inhibits the child, and his efficiency reduces. And the parents’ duty is to create conditions at home to meet the hygiene requirements of studying.
You should place the kid’s table so that the light out of the window illuminates the workspace properly. The light should fall on the left (on the right if your child is left-handed). You shouldn’t place the table parallel to the window – the natural light, when directed straight into the eyes, blinds the child, especially on the cloudless days.
Avoid the blackout curtains; don’t place high flowers on the windowsill. All these hold the light, dramatically reduce the illumination of the workplaces, and prevent the sunrays to penetrate into the depth of the room.
Do not underestimate the value of pure windows. And not only because of the aesthetic – a dirty glass blocks some light. Moreover, the cleaner the glass, the more ultraviolet light (it kills the pathogens). So, you should wash the windows more often.
In autumn and winter one puts the electric light on in the second half of the day. Therefore you need a desk lamp. Its light must also fall to the left (or to the right if your child is left-handed). The lamp must be covered with a shade so that the kid’s eyes don’t see the glowing light. The shade must create a good uniform illumination.
The best temperature for mental activities is 64,4-68°F in a well aired room at a relative humidity between 40-60%. Both too high and too low temperatures dramatically reduce your kid’s efficiency. As well as thermotaxis, heart and lungs will work with tension; your kid will rapidly get tired.
Cross-ventilation is the best way to quickly improve the quality of the indoor air (the child must leave the room). It is 5-10 time more effective than a normal one. However, be careful – drafts are dangerous.
Your child should understand that a fresh air is very important for his and his friends’ health.
It is very beneficial to the kid’s health if the fresh air enters the room continuously – through a transom window. It promotes hardening your child, the development of his ability to quickly adapt to changing temperatures.
To maintain a proper pose when studying in itself is a work for a little schoolchild. This work is not easy, and we, parents, must strive to alleviate it.
You should know that a working pose differently affects different body functions. For example, if a child writes or reads while sitting, his vision gets less tired. At the same time a sitting posture is tiring for the muscles of the trunk. If your child sits sharply bent at the table, the load is too great. So, this causes greater energy consumption, the nature of breathing changes and therefore, the heart starts working harder (intercostal spaces get much narrowed, preventing the rise of the diaphragm – and this leads to poor pulmonary ventilation and low oxygen saturation).
A less tiring posture is the one changing from a straight to slightly sloping. Unfortunately, sometimes parents wishing their kid only good (he must necessarily monitor the posture!) make the child sit straight all the time and not change the body position. And it is extremely difficult for the child – in 20 minutes, he begins to complain of pain in the neck and back, and tries to change the position that has become inconvenient.
Table and chair
The scholastic table and the chair should fit the proportions of the kid’s body. That’s a basic condition that helps you to save the least tiring body position. And at the same time it would promote a correct posture development, as well as prevent myopia and spinal curvature development.
Table height above the floor
Chair seat height above the floor
|110 – 119||52||32||27|
|120 – 129||57||35||29|
|130 – 139||62||38||29|
|140 – 149||67||41||34|
With the help of the table, you can set up the kid’s table in accordance with your kid’s height. The same table will help you adapt both an ordinary table and an “adult” chair. You’ll have to put a bench under the child’s feet, a hard pillow on the seat of the chair, and to attach a support to the back of the chair (in order to achieve its desired depth), a roll for example. Its height varies from 11 to 15 cm, depending on the child’s height.
Make sure that child sits at the table correctly. Of great importance is the distance from the eyes to the upper and lower lines on the pages of both a book and a notebook. Different distance to the upper and lower lines easily tires the eyes. The kid has to constantly adapt to the distance, to change the shape of his lens. Therefore, it would be good if you make a wooden stand with a board tilted at an angle of 12-15°. This will not only facilitate the work of the eyes, but also contribute to the development of a correct posture.
A notebook must lie against the center of the body. The child then won’t have to take the right hand far to the right or to the left. He’ll be able to maintain the correct position of the hands, arms, head and the entire body. That’s also convenient to his eyes.
An alarming signal is if your child bends the head over the table to reduce the distance to the book up to 25 cm, or, conversely, throws his head back in order to increase the distance up to 40 cm or more. You should urgently see an eye doctor. And if he prescribes eyeglasses, your duty is to ensure that the child wears them, otherwise his vision will inevitably get lower. Maybe you’ll have to help him overcome a false shame.
But a wrong posture during classes is not the only reason of persistent violations of posture and curvature of the spine. You should pay attention to the way your child stands, walks, and carries heavy items. Children often stand a wrong way, shifting all their weight on one leg.
If you constantly carry heavy bags, this has a negative impact on the posture. This also promotes the lateral curvature of the spine. Backpacks are the best option, for they provide a uniform load distribution (weight of the items inside) on the shoulder girdle.
