Evolution Of Math Instruction In California Public Schools.
Let's review the evolution of math instruction in
the California public schools:
Teaching Math in 1950:
A logger sells a truckload of lumber for $100. His cost of production is
4/5 of the price. What is his profit?
Teaching Math in 1960:
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?
Teaching Math in 1970:
A logger
exchanges a set "L" of lumber for a set "M" of money. The cardinality of
set "M" is 100. Each element is worth one dollar. Make 100 dots
representing the elements of the set "M." The set "C" -- the cost of
production -- contains 20 fewer points than set "M." Represent the set "C"
as a subset of set "M" and answer the following question: What is the
cardinality of the set "P" of profits?
Teaching Math in 1980:
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.
Teaching Math in 1990:
By cutting down beautiful forest trees, the logger makes $20. What do you
think of this way of making a living? Topic for class participation after
answering the question: How did the forest birds and squirrels "feel" as
the logger cut down the trees? There are no wrong answers.
Teaching Math in 2002:
A logger sells a truckload of lumber for $100. His cost of production is
$120. How does Arthur Andersen determine that his profit margin is $60?
Teaching Math in 2005:
Little Johnny Einstein flunks his California State Achievement Test in
math (CSAT) and sues Santa Monica Middle School # 101, School Superintendent Dr.
Marilyn Howard, and
the entire state legislature for $100 million. If the NEA lawyer
receives 4/5 of the frivolous award, how long will it be before the “Leave
No Child Behind” Act bankrupts the entire nation?
Teaching Math in 2015:
El hachero vende un camion carga por $100. La cuesta de production es...
