Note: Schooling for young people in the Martian colonies was much the same as schooling had been for hundreds of years on Earth, with children divided up into cohorts by age as a rough representation of learning capacity, and shuttled, as a cohort, from teacher to teacher each year. It wasn’t this way throughout the system, however. The spincities were already showing trends that leaned toward what we now call third-wave pedagogy, the system in which the cohorts are determined by AI testing, and children are sorted and resorted according to interest level and skill a dozen times throughout their education. In the more distant colonies, like Europa and parts of Galilea, students were few enough that there were no cohorts, only individualized A.I. teachers.
