US children learning with electronic devices
Like children elsewhere, children in the United States have greatly benefited from modern technology. School students in all grades know how to use electronic devices to look up and store information, do assignments and projects, do calculations and play games.
According to a new survey, about 2 out of 5 children in the USA have used a tablet, a smartphone or a similar mobile device before they could speak in full sentences.
For very young children, the devices may help promote listening and speaking ability. The devices may also help improve older children's critical thinking, reading, writing, and maths skills.
However, children's use of electronic devices has two sides. These devices can be great learning tools, but the wrong use may also cause very bad effects.
