Wiliam is talking about schooling, but it is also true of medical education.[Link].
“For me, I think the issue in the United States in particular is how we improve education at scale. I argue there are two things that have particularly powerful impact. One is a knowledge-based curriculum, recognizing that the purpose of curriculum is to build long-term memory into our students and what distinguishes novices from experts is knowledge not skills. And the second one is creating a culture where every teacher accepts the need to improve, not because they’re not good enough, but because they can be even better.”
I am pleased with the comment about long-term memory: intellect’s ballast. Knowing things matters.
