The year 2020? Maybe it's 2050. The bell rings, some hundred middle school students pile into a classroom and take their place in front of their PC. The teacher walks up, switches on the whiteboard. A few clicks on the laptop later she's ready with her multi-media presentation. The students are free to choose between the small and the big screen to follow the lesson.
Today, the PPT is on volcanoes. The graphics appear, and the kids watch unblinkingly. The main points of the lesson form the text, and the teacher fills in the details, answering questions. Just when student attention dims, a volcano erupts with a loud bang. Clap and cheer! Lesson over, the students take an e-quiz uploaded on the desktop. They search the Net for information, prepare answers, make their own graphics and save the answer sheet on the screen. Class dismissed. Classroom of the future
