I've tried the AI conversation with students more than once, and for a long time, none of it stuck.
The stern version ("this is cheating, don't do it") felt like reading from a script I didn't write, and it didn't survive the week. The warm version ("just use it responsibly!") sounded nice and meant nothing; "responsibly" just hung there while students quietly wondered what it actually allowed. The detailed version, twenty minutes, eight slides, every possible use case, was airtight and completely unmemorable by the time anyone actually needed it.
What finally worked didn't start with a rule at all. It started with purpose: naming out loud what I'm actually trying to help students learn before AI ever entered the conversation. Then we got honest about the gray areas instead of pretending every question has a clean answer because students can always tell when an adult is performing.
One real conversation which took maybe fifteen minutes was done on day one and has done more for me than any policy I ever wrote to defend myself later.
If you had to name, in one sentence, the actual capacity you're trying to develop in your students this year, what would it be, and have you said that sentence out loud to them yet?
