I have the wonderful opportunity of traveling the nation and internationally to speak about the wonderful miracle of the human brain. During my public presentations I always describe the brain as the most complicated, integrated, and miraculous system ever designed in the history of the Universe! I then scream from the mountaintops that we need to understand that our greatest moments of innovation, creativity, cures for illness, and ability to communicate in ways we only dream about now will be accomplished by learning how to tap into the greatness of our brain!
It is from this context that I read my local newspaper to find the following headline “Brains beat buttons for learning mathematics.” New research finds that third graders learn multiplication better when they use their brains before they use a calculator. The results of this study can be found in the next issue of the Journal of Experimental Child Psychology and the article is published in The Pittsburgh Tribune Review (Sept 4, 2008).
We have known for some time that learning is enhanced when the person doing the learning “does it on his or her own.” This is another way of saying “uses his or her brain.” We also know that the more one is exposed to a particular stimulus the more deeply they will remember or encode it. This again reflects the ability and efficiency of the human brain. The calculator is an external device that appears to have a secondary and reinforcing purpose to what the brain has already learned.
From a brain health perspective, we as a society will be better off when we use our brains first and rely on technological devices (invented by the human brain) in secondary roles. The former involves stimulation of the cortex that will develop brain reserve. A reliance on technologies such as a calculator will cause the brain to use the subcortex which is more rote, passive and procedural in its processing.
By using our cortex in complex pursuits we will always be on a path to brain health (brain fitness, brain games). Reliance on passive behaviors such as using a calculator will put us on a path to rote processing with less health benefit.
So… tonight I will remind my sons to use their brain first to solve the math homework as I have a personal interest in their learning and in their brain health!
