In C.S. Lewis' wonderful book The Magician's Nephew (in which he presents not only the beginning of the Chronicles of Narnia, but the creation of Narnia itself) he paints a picture of Uncle Andrew, a magician who has stumbled into Narnia on the day of its creation. Aslan, the great Lion, is singing Narnia into existence, and Lewis records:
"When the Lion had first begun singing, long ago when it was still quite dark, [Uncle Andrew] had realized that the noise was a song. And he had disliked the song very much. It made him think and feel things he did not want to think and feel. Then when the sun rose and he saw that the singer was a lion ('only a lion,' as he said to himself) he tried his hardest to make himself believe that it wasn't singing and never had been singing - only roaring as any lion might in a zoo in our world. 'Of course it can't really have been singing,' he thought, 'I must have imagined it. I've been letting my nerves get out of order. Who ever heard of a lion singing?' And the longer and more beautifully the Lion sang, the harder Uncle Andrew tried to make himself believe that he could hear nothing but roaring. Now the trouble about trying to make yourself stupider than you really are is that you very often succeed. Uncle Andrew did. He soon heard nothing but roaring in Aslan's song." (p117)Making yourself stupider than you really are
With respect to education it is quite possible that we are making ourselves stupider than we really are. Two years ago, I attended The Educational Equity Symposium. A very distinguished panel of guests, including Arne Duncan, who would in a few months be appointed US Secretary of Education, repeatedly said that what was needed to address the achievement gap was "more time on task," which translated into longer school days, longer school weeks, and a longer school year. It struck me as deeply ironic that none of the distinguished educators had needed the "more time on task" that they were so strongly commending - and they are at the very top rung of educational achievement and influence. It is, indeed, possible to make ourselves stupider than we really are.
So how do we know if we're making ourselves stupider?
Obviously the trouble is that we are, almost by definition, unaware of making ourselves stupider. So what are some of the clues that we might be? If we fail to read, to listen, or to ask hard questions, it is likely that we're making ourselves stupider. Ultimately, what we perceive as reasonable rests on the lenses through which we make sense of the world. If we start with the assumption that lions only roar, we may hear roaring when there is actually a voice singing. If we assume that increased instructional time results in higher achievement, then we may well not recognize what caused the disparity that increased instructional time is attempting to mend.
