If nothing was unclear or difficult, say so. Skip questions about steps you did not experience; use not applicable where appropriate.

How was your group's task explained?
What made participation easier or harder?
What facilitation change would help?

Author notes / illustrative keys where applicable:
1. Use this answer to locate the part of the experience that needs explanation. The example issue to investigate is: groups spend time interpreting different instructions.
2. Participation conditions distinguish unclear roles, preparation gaps and interaction preferences during a group task. Adjust the relevant arrangement while preserving voluntary options; quiet participation does not establish lack of learning or interest.
3. Turn the requested improvement into a testable next step. One illustrative action is: give a consistent written task brief.
