This review explores how schools are primarily designed to maximize motivation rather than learning, explaining why age-graded classrooms and seemingly inefficient group learning have persisted despite numerous attempts at reform. Longer summary

The post examines why schools have maintained their traditional structure of age-graded classrooms where all students learn the same content, despite its apparent inefficiencies. The author argues that schools are designed primarily to maximize motivation rather than learning, using conformity as a key tool. Through analyzing various attempts at personalized learning and their consistent failures to scale beyond about 5% of students, the post explains how students fall into three categories: no-structure learners, low-structure learners, and high-structure learners. The author concludes that while the current system is far from perfect, it has proven more effective at scale than any alternatives, predicting that despite continued attempts at reform, the basic structure of schooling will remain unchanged.
