The Himba tribe in Namibia have only one word for the colors blue and green: zuzu. Some researchers, notably Jules Davidoff of University of London, claim tribal members cannot distinguish between color swatches of blue and green.
What does this have to do with teaching?
It might mean that if people are not exposed to an idea, they are unable to perceive it on their own. If ideas like blue and simultaneous do not exist for people who have never been taught them, then what does it mean when our curriculum shrinks due to the pressures of high stakes testing?
Schools are under enormous pressure to produce higher and higher reading and math scores. Teachers are being told by their administrators to skip teaching writing, social studies, geography, art, science, civics, foreign languages and other non-tested subjects, in order to boost the teaching time for the tested subjects.
Some of this loss might be mitigated with a rich and diverse reading curriculum, but most schools are demanding teachers stick with skill-based reading programs where the subject being taught is actually a technical analysis of reading—not literature. As a result, students in lower grades read one story a week and spend the rest of their instructional time studying skills like hard and soft g.

By basing teacher salaries, principals’ jobs and even the existence of schools on student test scores, our policy makers are causing a collapse of our formally rich curriculum and simultaneously hobbling our children’s minds. These policy makers just can’t see what they are doing.
