Several Observations
Real Time is an extension of the frontal lecture
• Easier to introduce
• Conserve current pedagogical paradigms (for better, for worse)
• Limited distribution
With Telephone and TV
it is not so
much the message
as the sender that is "sent.”
Marshall McLuhan
Is the “Presenter” important ?
Delayed Time introduces novel concepts
• Forces new pedagogical paradigms For the students: self study For the teachers: new roles
• Wide distribution
I don't know what is
inside (the vault); maybe
it's nothing. I just sit and
start to work. I grope, I
listen, I test, I accept and
discard; I try out
different sequences -
until the tumblers fall
and the door spring open.
Marshall McLuhan
By creating a speed of information
movement unthinkable before printing,
the Gutenberg revolution thus produced a new type of visual centralized national
entity… Marshall McLuhan

The use of the electronic media
constitutes a break boundary
between fragmented Gutenberg
man and integral man…
