One point, though. You write:

rather that small changes in policy, and particularly changes in the ways in which teaching is assessed for junior scholars and for departments

At my university, that would be a BIG change. A good one, IMHO. But it would be a significant culture shift. Some faculty suspect, “Teaching is for people who aren’t good enough to do research.”

It might be better – again, just at my school – to focus on grizzled faculty like myself, to let us do the experiments. We have tenure, and are less likely to care what others think. We’re going to die soon, anyway. :-)

But I do like your ideas.
