From the Classroom to the Armchair,

In praise of

Technology

The Medium is the Message. Marshall McLuhan

For 2000 years the mightiest streaking force,

Suddenly in WWI it came to an end.

And the trenches became the ultimate defensive line,

Yet they failed completely in WWII because of the tank.

But, would the tank stand this … ?

Presenter Reader

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
