Herewith, a simple way to understand the destructive failure of most reading instruction in the United States.
Consider our eyes. Their purpose is to grasp quickly what objects are: food or predator, useful or irrelevant? This is often a matter of life and death. How do eyes do their job?
Eyes twitch, jerk, and flick rapidly from detail to detail in order to identify an object. There are no built-in sequences, no shortcuts. The eyes must twitch – perhaps dozens of times – until a positive identification is made. The technical term for these twitches is a saccade (which rhymes with façade).
Many such eye movements occur every time you see a car, painting, building, celebrity, insect, etc. Your eyes flick top-to-bottom, side-to-side, point-to-point, finding more and more details until the brain is certain.
Scientists can track these eye movements. It’s remarkable how much activity is required to identify a single face – that is, to be sure it’s not a similar face. The eye might go to the ears, then nose, then lips, back up to the hairline, and around again. There might be 10, 20, or 30 saccades before you confidently decide, “This is Mary in accounting.”
When the first symbol languages were introduced, such as Egyptian hieroglyphics, nothing changed. A picture of a bird is the same as a real bird, from the point of view of the eyes making sense of it. Designs such as Chinese ideograms are again the same thing. Hieroglyphics were objects just like birds and flowers.
