It is obvious that children learn more when they engage their entire body in a meaningful experience than when they sit at a computer. If you doubt this, just observe children watching an activity on a screen and then doing the same activity for themselves. They are much more engaged riding a horse than watching a video about it, playing a sport with their whole bodies rather than a simulated version of it in an online game.
Today, however, many powerful people are pushing for children to spend more time in front of computer screens, not less. Many adults appreciate the power of computers and the internet, and think that children should have access to them as soon as possible. Yet screen learning displaces other, more tactile ways to discover the world. Human beings learn with their eyes, yes, but also their ears, nose, mouth, skin, heart, hands, feet. The more time kids spend on computers, the less time they have to go on field trips, build model airplanes, have recess, hold a book in their hands, or talk with teachers and friends. In the 21st century, schools should not get with the times, as it were, and place children on computers for even more of their days. Instead, schools should provide children with rich experiences that engage their entire bodies.
