The document discusses the concept of "Demand High" teaching, which argues that students are often under-challenged and capable of more than teachers demand of them. It provides assumptions about how most teaching settles for "good enough" and avoids challenging students, and suggests ways for teachers to increase demands on students through techniques like checking answers more rigorously and focusing on pronunciation. The goal of Demand High teaching is to transform the focus onto facilitating deeper learning by pushing students to their potential.
