"When learning maths, abstract symbols work better than real-world examples"
from Not Exactly Rocket Science
I found the post interesting, maybe it's time to rethink (again) our ideas on education...
excerpt:
You all know the score. A train leaves one city travelling at 35 miles per hour and another races toward it at 25 miles an hour from a city 60 miles away. How long do they take to meet in the middle? Leaving aside the actual answer of 4 hours (factoring in signalling problems, leaves on the line and a pile-up outside Clapham Junction), these sorts of real-world scenarios are often used as teaching tools to make dreary maths "come alive" in the classroom.
Except they don't really work. A new study shows that far from easily grasping mathematical concepts, students who are fed a diet of real-world problems fail to apply their knowledge to new situations. Instead, and against all expectations, they were much more likely to transfer their skills if they were taught with abstract rules and symbols.

It's Hard to Thaw a Frozen Market
Commentary about the American financial market. Excerpt below:
"Starting in the 1920s, Ludwig von Mises, the leader of the so-called Austrian School of Economics, charged that socialism was unable to engage in rational economic calculation. Without market prices, he reasoned, no one knows how much economic resources are worth.
The subsequent poor performance of planned economies bore out his point... ... The irony is that the supercharged capital markets of the American economy are now — at least temporarily — in a somewhat comparable position. Starting in August, many asset markets lost their liquidity, as trading in many kinds of junk bonds, mortgage-backed securities and auction-rate securities has virtually vanished."

it makes us happy when...
we spend on others, apparently.
This research is being floated around so often I thought I should note it. Maybe I should start treating my colleagues to lunch or something...
