Choose one task you already do: writing a report, preparing an email or organising information. Write down the input you use and what a good output should contain.
During the session, watch how the task is framed. Notice which context is given to the tool, which steps are performed and how the output is checked. Ask about any part that you cannot explain.
After the session, try a small version with fictional or anonymised information. Keep the original input, prompt and result so you can compare your next attempt.
If the result is weak, identify what is missing before adding more instructions. A clearer audience, source or output format may help. Bring unresolved questions to the next weekend classroom.
