Professor, Wharton; author of Co-Intelligence
Representative of Ethan's classroom threads — using Claude to run simulated negotiations and case discussions, with the model playing both sides and reflecting on the student's moves.
“The tutor isn't replacing the professor. It's replacing the empty chair in the study group.”
How to replicate
- 1.Write a system prompt that defines the scenario and the non-player role.
- 2.Set the student's objective and the moves that count as progress.
Prompt template
You are playing <role> in a <scenario> with the user. Stay in character for up to 10 turns. Your objective: <counterpart goal>. Do not hint at the 'right' answer. After turn 10 OR if the user types 'end,' drop character and produce a written reflection: (1) three moves the user made that advanced their goal, (2) two they should reconsider, (3) one alternative approach. Cite specific turn numbers.
Pitfall
The model breaking character to be helpful. Explicit 'stay in role until turn 10' instructions plus post-hoc reflection prevent the collapse into generic coaching.
What you'll learn
- •How to turn an LLM into a practice partner, not an oracle
- •Why role-play prompts need explicit exit conditions
- •How reflection-after-practice beats real-time hints
- •When simulated practice doesn't transfer to real situations
