An anonymous reader writes: It what is believed to be the most ambitious project of its kind in the world. In a program called Enciclomedia, giant electronic screens have been attached to the walls of about 165,000 Mexican classrooms. Some five million 10 & 11 year-olds now receive all their education through these screens. From maths to music, from geography to geometry, black and white boards have given way to electronic screens. During a biology lesson we watch as pupil after pupil comes to the screen to piece together the human body... electronically. One boy taps his finger on the screen and brings up the human heart. He then slides his finger across the screen, taking the heart with him and places it where he thinks it belongs on the body located on the other side of the screen.
