Used carefully, the Internet can be helpful for doing a number of things, I'd acknowledge. But it is definitely a very poor environment for education and learning because it destroys the carefully-designed school learning process. Effective education and learning needs a controlled environment, one that is designed by instructors, professors and education experts for maximum transfer of knowledge. If you want exposure to the real world, you go on a field trip. Even such field trips must be carefully planned, to optimize the learning process.
Education also means learning to work with high-level symbols.
It means going beyond the level that is directly appreciated by our five senses, the sensory level, and thinking in more abstract terms. The Internet, however, is moving in the opposite direction. Increasingly advertising-driven, it is moving away from abstract symbols, towards the purely sensory level, the level that demands the least from its users. They are now talking of three-dimensional video and, beyond that, of virtual reality using tactile suits. Television had initially promised to become a revolutionary educational tool that would abolish mass ignorance and raise the cultural level of the masses.
