The Evolution of Mathematics

(Am primit-o de la Daniel George, un prieten vechi si bun)

I purchased a burger at Burger King for $1.58. The counter girl took my $2 and I was digging for my change when I pulled 8 cents from my pocket and gave it to her. She stood there, holding the nickel and 3 pennies, while looking at the screen on her register. I sensed her discomfort and tried to tell her to just give me two quarters, but she hailed the manager for help. While he tried to explain the transaction to her, she stood there and cried.. Why do I tell you this? Because of the evolution in teaching math since the 1960s:

1. Teaching Math In 1950s (when I was in school) A logger sells a truckload of lumber for $100. His cost of production is 4/5 of the price. What is his profit ?

2. Teaching Math In 1970s A logger sells a truckload of lumber for $100. His cost of production is 4/5 of the price, or $80. What is his profit?

3. Teaching Math In 1980s A logger sells a truckload of lumber for $100. His cost of production is $80. Did he make a profit? Yes or No

4. Teaching Math In 1990s A logger sells a truckload of lumber for $100. His cost of production is $80 and his profit is $20 Your assignment: Underline the number 20.

5. Teaching Math In 2000s A logger cuts down a beautiful forest because he is selfish and inconsiderate and cares nothing for the habitat of animals or the preservation of our woodlands. He does this so he can make a profit of $20. What do you think of this way of making a living? Topic for class participation after answering the question: How did the birds and squirrels feel as the logger cut down their homes? (There are no wrong answers, and if you feel like crying, it’s Okay).

6. Teaching Math In 2014 Un hachero vende una carretada de maderapara $100. El costo de la producciones es $80. Cuanto dinero ha hecho? ANSWER: His profit was $375,000 because his logging business is just a front for running drugs across the border.

  1. Se numeste reconquista, daca nu ma insel …
    Ca unul care am fost de cateva ori in Mexic, am ajuns sa cred ca cea mai mare greseala pe care au facut-o cei de acolo a fost sa nu introduce limba engleza obligatoriu in programa scolara. Inca nu e prea tarziu, dar nu sunt semne ca cineva si-ar da seama de aceasta prioritate. Mexic ar putea trai capusand sistemul de educatie din America, plus o serie intreaga de alte avantaje … Daca Romania ar avea granita comuna cu USA, cam toti romanii ar sti limba engleza.

  2. Ca idee, traind in zona Houston, TX sunt zi de zi nas-n nas cu o sumedenie de “sud dunareni”, unele cartiere de prin preajma fiind ticsite de ei in proportie de 95%, desi numele suburbiei suna destul de pompos si frumos ca Summer Hill, Timberland, si altele…
    O chestie totusi de remarcat si va rog sa fiti atenti si constienti:

    La inceput, colonistii si apoi americanii au luptat pentru cucerirea teritoriilor pe care astazi le cunoastem sub denumiri ca Texas, New Mexico, California… Acum, mexicanii isi recuceresc teritoriile inapoi, dar pe cale pasnica. Invazia lor e fara arme si fara lupta, dar in aceste state, daca nu sti limba spaniola, nu poti gasi un job bine platit sau intr-o pozitie buna. Oriunde te duci sa te angajezi, esti intrebat daca sti sau macar intelegi limba spaniola. Daca in resume-ul (CV-ul) tau nu ai trecut si optiunea asta, esti la un nivel inferior. Nu conteaza ca ai invatat franceza, germana, italiana, greaca sau mai stiu eu care alta limba, incluzand romana. Daca spaniola nu stii, nu existi.
    Asta e felul in care mexicanii si-au recucerit teritoriile inapoi.

    Judecati singuri daca am dreptate sau nu… cei care locuiti in ariile amintite, mai ales in zonele sudice ale statelor respective, stiti ce spun, cu siguranta!

  3. Am citit cu placere de la inceput, incercand sa rezolv cat de repede am putut. recand la urmatoarea sectiune de ani si recititnd enuntul problemei am inteles siretlicul si am savurat expunerea pana la sfarsit cand am citit enuntul problemei in limba dragilor nostri “compatrioti” de la “sud de Dunare”. Asa le spunem noi mexicanilor cand suntem in public ca sa nu se prinda nimeni despre ce vorbim, chiar daca vorbim o limba diferita. M-am amuzat copios atat de evolutia predarii matematicii in SUA, dar si de raspunsul unui posibil elev/student… din pacate, de multe ori, foarte adevarat.

    Totusi, amuzant…

  4. Foarte adevarat din pacate
