2. In-depth analysis:
(1) Staring at the computer screen for a long time will lead to visual fatigue and damage your eyesight. Especially for children in the stage of vision development, this effect is more serious. Children should be reminded to rest their eyes every half hour or so to relieve visual fatigue from time to time.
(2) Long-term concentration will cause attention fatigue and affect thinking and memory. This will lead to obstacles in the acceptance and understanding of online courses, especially in the later stage of online courses. Simple off-screen activities, such as exercise and deep breathing, can be arranged between online classes to improve attention.
(3) Being in the same sitting position for a long time will also have an impact on health, such as neck and shoulder pain and gastrointestinal dysfunction. Children need to be reminded to do simple stretching exercises during online classes, or to move outside the camera and change their posture. Provide nutritious snacks such as fruits regularly to relieve physical discomfort.
(4) Long-term isolation from peers will aggravate depression and anxiety and affect mental health. In order to encourage friendship and interaction between online courses, some online games or social activities are recommended. Parents should also communicate with their children more, pay attention to their psychological status and seek professional psychological guidance when necessary.
(5) Long-term online classes will reduce outdoor activities and affect growth and development. Children should be encouraged to take part in outdoor activities, especially sports, after online classes. If conditions permit, you can also choose to take your children to participate in club activities in the morning and evening to ensure 1-2 hours of exercise every day.
(6) In the process of implementing the online class, if the above symptoms appear or the child shows strong discomfort, the time or content of the online class should be adjusted in time. You can also choose offline classes to carry out part of the course content, and appropriately reduce the online class load to ensure the balance between the online class effect and the healthy development of children.
