SAT score decay
----------------------------------------------------------------------------
As we all know SAT scores have been on the decline for years.
The following may be the reason why.
A math problem in the 60's
A logger sells a truckload of lumber for $100. His cost of production is
four-fifths of this price. What is his profit?
A math problem in the 70's
A logger sells a truckload of lumber for $100. His cost of porduction is
four-fifths of this price, or $80. What is his profit?
A math problem in the 70's using New Math
A logger exchanges a set L of lumber for a set M of money. The cardinality
of set M is 100, and each element is worth $1. Make 100 dots representing
the elements of set M. The set C of the cost of production contains 20 fewer
points than set M, and answer the following question: What is the
cardinality of the set P of profits?
A math problem in the 80's
A logger sells a truckload of wood for $100. His cost of production is $80,
and his profit is $20. Your assignment: underline the number 20.
A math problem in the 90's under Outcome Based Education.
By cutting down beautiful forest trees, a logger makes $20. What do you
think of this way of living? (Topic for class participation: How did the
forest birds and squirrels feel?)
