Most teachers have very little clue about pedagogy; let's be honest about it. And it does not mean they are incompetent at their subjects or lazy.

The fact that, outside of the expected exceptions, a skill/subject/section is never brought up after the test means that teachers are not thinking at all about retrieval practice. There is a time for understanding and justifications, and a time for saying things as they are.

Then, my personal experience and that of my friends, who all attended mid- to high-ranking schools outside the United States, is that regardless of class size and teacher workload, teachers never seemed to know how to teach effectively and efficiently.
