Each chatbot response will be different. Use the variety in the responses as an evaluation piece. How? With a thought-provoking question or prompt:

•Students use different chatbots or models (eg ChatGPT 3.5 vs 4.o) with the same question and evaluate the different responses.

•Students try prompts and get responses. They look to improve their prompts to improve the response. Discussion/evaluation/reflection can come from this.
