As a K12 practitioner, I'm wondering if your group spent any time thinking about the same problem, but with foundational skills. This affects the first consensual question of who the course is for. Do you see what I mean? What can you tell us about the evolution of students profile/skills when they first get to your course? Is it too early still?

The question of whether we can exercise judgement without doing is really interesting.

The sociologist Harry Collins has an interesting take on this when he separates "interactional expertise" from "contributory expertise." Contributory expertise is the ability to do a task (which entails judgements that become somewhat taken-for-granted for the expert, a matter of tacit knowledge) and interactional expertise is the ability to talk about the task to an expert in ways that the expert will appreciate and will contribute to the discussion but without the ability to actually do the task.

The relationship between contributory and interactional expertise is complicated. Tennis coaching requires interactional expertise; but tennis coaches often were players before they became coaches (probably not great players but still; that said, not every good player can be a good coach). A science journalist immersed in the science they cover is probably an interactional expert but not a contributory one (though often we see science reporters have a background in doing science). Research managers often start off as researchers but once they become managers, they lose the ability to actually do an experiment.

In statistics, of course, there are people who can actually do statistics; but a lot of researchers are able to talk about statistical results with fluency.

I think part of getting AI to do certain tasks is that we are going to have to think carefully about what expertise we want to develop in people: the boundary between contributory and interactional expertise will have to shift. But for that, I think, we're going to have to decide what's important. So in that sense, this was a very enlightening read because it gave me the sense that even statisticians are figuring out these boundaries.

Collins has many publications but this is my favorite one: it's a response to Hubert Dreyfus' analysis of what AI (the old-school one) can and can't do. https://www.sciencedirect.com/science/article/pii/0004370296000836
