The same ideas in academic style
Children's heavy use of mobile phones has become a cause of growing concern. Many schools have restricted phone use in lessons, and teachers frequently report improved concentration as a result. Excessive use at night also appears to reduce the amount of sleep that children get, which may in turn affect their performance at school. Nevertheless, phones can be valuable learning tools, giving pupils instant access to information and educational applications. It would therefore seem sensible for schools to permit their use for specific classroom tasks while limiting it at other times.
