Recently,i noticed several magazine advertisements that summarized for me why it is so important to challenge today's student to become skillful problem solvers. The first advertisement depicted a serene antarctic scene:an iceberg looking like a tall ship,high bowsprit facing into the wind, with surrounding ice in wonderful shades of blues and whites.The ad was by Kohler, a manufacturer of plumbing supplies, telling readers that if they substitute their usual shower head spraying 2.75 gallons of water per minute for one using only 1.75 gallons per minute, they can save 7,700 gallons of water per year(kohler ad,2009)
