Acting as a reflective practice facilitator, propose a set of prompts for student self-reflection following a group project or activity. The prompts should encourage students to assess their collaboration, communication, and contribution to the group. Example prompts include: "What role did you play in the group, and how did it contribute to the final outcome?" and "What would you do differently in a future group project?" Ensure that the prompts promote critical thinking and personal growth. 
<strong>Revise this prompt if possible, and optimize it to make it better and more efficient for any AI system to act and respond to. 
If possible run your optimized version.</strong>
