Today, I take the liberty to reproduce an e-mail .. I was worried or not?
Story of a teacher:
Last week I bought a product that cost $ 1058. I gave the cashier $ 2000 and looked in his pocket $ 8 to avoid getting more pennies. The cashier took the money and stared at the cash register, apparently not knowing what to do. I tried to explain that she had to give me $ 950 change, but she was not convinced and called the manager to help her. He had tears in his eyes while the manager tried to explain and she apparently still did not understand.
Why am I telling you this?
Because I noticed the development of education since 1960 and current conditions are handled in many public schools and worse in private, both in the field academically and in the treatment of students, (now the students, apart from irrelevant are "untouchable" providing educational institutions and dire despots generations to society)
See how was the change in the mathematical area, examples were as follows:
1. Teaching Math in 1960:
A woodcutter cart firewood sells for $ 100.00. The cost of production of the fuel truck is equal to 4 / 5 the price of the sale.
What is the gain?
2. Teaching Math in 1970:
A woodcutter car sells firewood for $ 100.00. The cost of production of the fuel truck is equal to 80% of the sale.
What is the gain?
3. Teaching Math in 1980:
A woodcutter cart firewood sells for $ 100.00. The cost of production of the fuel truck is $ 80.00.
What is the gain?
4. Teaching Math in 1990:
A woodcutter cart firewood sells for $ 100.00. The cost of production of the fuel truck is $ 80.00. Choose the correct answer indicating Gain
() $ 20.00 () $ 40.00 () $ 60.00 () $ 80.00 () $ 100.00
5. Teaching Math in 2000:
A woodcutter cart firewood sells for $ 100.00. The cost of production of the fuel truck is $ 80.00. The profit is $ 20.00.
Is it right?
() Yes () No
6. "Teaching Math in 2010?:
A woodcutter car sells firewood for $ 100.00. The cost of production of the fuel truck is $ 80.00. If you can read place X in the $ 20.00 represents the gain ..
() $ 20.00 () $ 40.00 () $ 60.00 () $ 80.00 () $ 100.00
I hope not.
