Students Learn Better When The Numbers Don't Talk And Dance

Found this rather old entry on ScienceDaily.

"Researchers found that when college students were taught an artificial form of mathematics and physics, they learned it better when it was presented using simple, abstract symbols ... rather than more visually engaging and concrete 3-D objects that moved dynamically on a computer screen."

This finding seems to support the idea that it is more effective to teach law and economics using abstract mathematical concepts than 'talking' about some intuitive economic concepts with minimal math.
