Technology in
Education

2. All the world’s a stage ...
And all the men and women merely players:
They have their exits and their entrances;
And one man in his time plays many parts,
His acts being seven ages…
William Shakespeare
As you like it
3. Seven ages
At first the infant
And then the whining school-boy
And then the lover
Then a soldier
And then the justice
Into the lean and slipper'd pantaloon
Second childishness and mere oblivion
4. At first the infant
Small byte sizes
Scares easily
Computer is a typewriter and calculator
Violent reactions to anything foreign
5. Remember when
A computer was something on TV Compress was something you did to the
From a science fiction show. garbage,
A window was something you hated to Not something you did to a file.
clean, And if you unzipped anything in public,
And ram was the cousin of a goat. You'd be in jail for a while
Meg was the name of a girl, Log was adding wood to the fire.
And gig was your middle finger upright. Hard drive was a long trip on the road.
Now they all mean different things, A mouse pad was where a mouse lived,
And that really mega bytes! And a backup happened to your commode..
Memory was something that you lost with Cut you did with scissors,
age. Paste you did with glue,
A CD was a bank account. A web was a spider's home,
And if you had a 3 .5" floppy, And a virus was the flu.
You hoped nobody found out! I guess I'll stick to my pad and paper
And the memory in my head.
I hear nobody's been killed in a computer
crash,
But when it happens they wished they were
dead!
6. And then the whining school-boy
Objects to everything
Bucks the system
Copies homework
Creeping like a snail … unwillingly to
school
7. And then the lover
Technolphile
Pornographer
Surfer
11. What is this?
f(z)=z2/(z9-z+0,025), shown on[-2;2]x[-2;2].
12. What is this?
The are all Julia sets, but what is a Julia set?
If a function f maps a region G to itself, f
can be iterated. The Julia set of f then is the
set of all points of G, at which this sequence
of iterated functions is not equicontinous.
15. The lover of technology
Home is where you hang your @
The E-mail of the species is deadlier than the mail.
A journey of a thousand sites begins with a single click.
You can't teach a new mouse old clicks.
C: is the root of all directories.
Pentium wise; pen and paper foolish.
The modem is the message.
Too many clicks spoil the browse.
The geek shall inherit the earth.
Don't byte off more than you can view.
Fax is stranger than fiction.
What boots up must come down.
Windows will never cease.
In Gates we trust.
Virtual reality is its own reward.
There's no place like http://www.home.com
16. And finally...
Give a man a fish and you feed him for a
day;
teach him to use the Net and he won't bother
you for weeks.
17. Then a soldier
Technology strategies
In-fighting
Control measures
Imagine a group of surgeons ...

28. I VERSUS C?
Instructivism: How to put knowledge across.
Constructivist: How do we learn?
They are NOT opposites
They are at CROSS PURPOSES
Therefore they cannot be plotted at 180
29. But must we decide?
Instructivist: Benefits/Disadvantages
Constructivist: Benefits/Disadvantages
Since they are not exclusive opposites…
How can we draw from both?
ENTER the MATRIX
31. Judging the strategies

Subject choices
Computer staff
Selection of software
Selection of hardware

Retirement plans for old equipment
Letting go
Allowing others to lead

processing)
Opportunity (one computer per hundreds)
38. Second childishness and mere
oblivion
Crying over missed chances
OR
Looking forward to new beginnings!
39. … or Looking forward to new
beginnings! – What winning
schools have in common
Learners learn by doing
Learners produce learning materials
Schools develop their own software and websites
Research done by learners
Focus on learning, not on technology
Make magic out of nothing
Computers across the curriculum – integrated & thematic
Educator training
Community involvement, outreach and sharing
Focus on girls
International links
Future plans
40. Remember
Teach a man to fish...
And he’ll sit in a boat drinking all day
