I visited my old school yesterday. It hasn’ t changed in thirty years. The pupils were sitting in the same desks and reading the same books. When are schools going to move into the modern world? Books belong to the past. In our homes radio and television bring us knowledge of the world. We can see and hear the truth for ourselves. If we want entertainment, most of us prefer a modern film to a classical novel: if we want information about anything, we can use computers, so that we no longer need dictionaries. But in the schools teachers and pupils still use books. There should be a radio and television set in every classroom, and a library of tapes and records in every school. The children of today will rarely open a book when they leave school. The children of tomorrow may not need to read and write at all.
