Progress in Math

My last post described a situation that points to the dishonesty of public education bureaucrats. I must apologize for the rather gloomy outlook presented—but I honestly believe that unless or until people start demanding a higher standard in the educational process, we will never achieve it. Worse, there will be a long term and near-disastrous consequence to our collective failures in this regard.

Since then, my long-time friend Andy sent the following observation in an email; he may not be the original author, but it is relevant to my previous discussion and it takes on a somewhat lighter (humorous) tone about the state of American education. Andy served as a schoolteacher for fifteen years, finally giving it up as a lost cause and a waste of his time and effort. Even as you may chuckle at some of this, also consider that there is a serious undertone. If anyone is “offended” by the attempt at humor — too bad.

“Last week 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 ‘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 1950s:

1. Teaching Math In 1950s

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 1960s

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 1970s

A logger sells a truckload of lumber for $100. His cost of production is $80. Did he make a profit?

4. Teaching Math In 1980s

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 1990s

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? (Instructional note: There is no wrong answer; and if you feel like crying, it's okay.

6. Teaching Math In 2007

Un hachero vende una carretada de maderapara $100. El costo de la producciones es $80. Cuanto dinero ha hecho?
