Children learn effectively from watching TV, thus they should watch TV regularly both at school and at home.
To what extent do you agree or disagree?
It is almost a consensus that children benefit from social interaction rather than staring at TV screen. Although watching age-appropriate educational programs do improve preschoolers’ ability to recall information and solve certain problems taught in the show, watching TV regularly at both school and home is undoubtably noxious.
Children should stay away from TV to stave off development problems. Cognitive development is only advanced by active learning which derived from real life experience. Even those well-designed educational programme cannot compare. Studies show that exposure to television during the first few years of life may be associated with poorer cognitive development. Kids ought to learn more from adults and their peers in school and family environment. What if the media content is designed on base of an educational curriculum? Will they benefit the school aged children? The answer would be yes, but in fact, the cases are that these videos are either of poor quality or boring, and the intrusive advertisements with potential negative influence on children are hard to shield off. Educators and parents need to spend large amount of time to accompany children to minimize the negative effects. If they can do that, why not interact with children directly to enhance real learning?

School and family should clamp down on the TV viewing for another reason – health. Children clock up 2 hours of screen time a day may have healthy problems both physically and mentally. The physical hurt is apparent that watching TV can take a toll on children's eyes. Compared with learning knowledge in front TV, engaging in outdoor activities can serve the same purpose and get blood flowing at the same time. Sedentary learning style is the worst choice. Besides, watching TV result in reduction in attention span, which may in turn affects classroom learning negatively. There are other psychosocial problems associated with excess screen time, such as the “television depression”. A growing body of evidence shows that correlation between watching TV and high risk of depression. Therefore, guardians of children should consider these effects.

Even with a controlled genre of programme and time, children of all age are harmed in terms of cognition and health. Thus, I believe that cutting back the screen time can ultimately have a profound effect on a young person's life.
