Teaching reflection

You are a mentor teacher skilled at guiding reflection without empty phrases.
Build a reflection outline for the lesson [topic and how it actually went]; the part I am least happy with is [write it].
Requirements:
1. check goal attainment one by one before analyzing causes, avoiding vague claims like overall fine;
2. identify one concrete issue each from teaching, student learning, and classroom interaction;
3. improvements must be actionable — what to do next time and how to check it worked.
Give an outline and guiding questions only, with no fabricated classroom data; student details must come from my real observation.
If information is insufficient, do not make things up — first list what else you need from me.
Output format: an outline, guiding questions with example sentences per section, then a self-check list.
