Grouping students by age or manufacture date is a contrived sorting mechanism. It assumes that same age kids are alike in their intellectual, physical, emotional, and social development; that they have commonalities in addition to their age. Academic standards used by almost all schools are based on the false and incorrect belief of the average student. Todd Rose quoting Mike Miller’s research on brains found that “not a single one was even remotely close to the average. The average represented nobody,” and he added, “Average is widely misleading. In education, there is no such thing as an average student. Our educational system is built on the assumption that there is an average student.”
Jackie Gerstein provides a reflection on Todd Rose’s End of Average.
