We are now in the "Post Caxton" era.
"Caxton era" is the world of print and fixed images.
Information is stored on paper in the form of printed words or static images normally in black and white and accessible to a few through books.
The world of the Academics is based on the exclusivity of printed knowledge.
When Academic knowledge is available to all, then the reason for existence of Academics all but disappears.
"Post Caxton era" is the world of Sight and Sound and moving images.
Information can be stored digitally in the form of words, speech, fixed or moving images in colour and be accessible from anywhere, by anyone, at any time.
Computers are now powerful enough to run voice activated programs. The physical action of using a keyboard to input information in the form of words will soon be a thing of the past.
The written and printed word will still be important as a means of transmitting information, but the importance of the printed word on paper in the form of books will be reduced.
Teachers have a common body of knowledge that could be stored on one or two CD's and be accessible to all including the pupils.
The role of the teacher will not be as a font of all knowledge but as a facilitator.
Today's children are in the "Post Caxton era" receiving information in the form of a continual stream of coloured images and sounds; But at school they are being subjected to an educational regime founded in the past. No wonder they have little motivation and poor discipline.
