Slightly different, but in my science writing class I make my students work in a Google doc so I can see the history of how the piece came together. Their grade is based on effort rather than the final product. So far, AI use is not an issue with this approach.

Maybe it is just me, but I don't really care about academics posting about the secondary things (grants / awards) on social media. But I do care about and want to see is the primary thing that matters in science, the work / papers you have done.

We attempt to survey the two different universes of motor learning research: basic (meetings like NCM, MLMC) and applied (e.g. NASPSA), and consider what these fields can learn from each other and what the future might look like if they can be better integrated.
