A farmer sells a bag of potatoes for $100. Production costs used 4/5
of the sales price. What was his profit?

Traditional teaching in the 70’s:
A farmer sells a bag of potatoes for $100. Production costs used 4/5
of sales price, that is, $80. How much was his profit?

Modern teaching in the 70’s:
A farmer exchanges a set "P" of potatoes for a set "M" of money. The
order of the set "M" is 100 and each element is worth $1. Make a draw
of 100 dots representing the elements of the set "M". The set "C" of
the production costs has 20 dots less than the set "M", so answer now
the next question:
What is the order of the set "B" of profits? (draw its elements in

New teaching system of the 80’s:
A farmer sells a bag of potatoes for $100. Since the production costs
were $80, the profit was $20.
Now, underline the word "potatoes" and discuss it with your class

Reformed system of the 80’s
A privileged Kapitalist steels injustly $20 over a beg of patatous
analize the text and find out gramatik. ortografy and ponctuation
erros and say something about dis process of getting reach.

Computer Aided Instruction in the 90’s:
A sells engineer of an agriculture facility consults the Agro-BBS
which he accesses through a PS/2 running OS/2 (50Mb hard disk, 4Mb 80
ns RAM, 25 MHz 80386) to find out the current day’s price of potatoes.
He introduces the value in his spreadsheet program, analyses linear
regression tendencies in his FARMMANAGER expert system, and after
seeing the results in his new VGA-compatible multisync monitor, and
saving the results in the disk (not forgetting to back up the data) he
outputs the result to a color laser printer (using Post Script).

Make a drawing with your mouse of the 3-D integrated contour of a bag
of potatoes. Next, log into the Agro-BBS and follow the instructions
of the menu.

Teaching in 2000:

What’s a farmer?
