Definition
In a guided discussion, the opening question used by an instructor to introduce a topic and start students thinking and talking about it. A lead-off question is open-ended, calls for an extended response rather than a yes/no answer, and is designed to launch group discussion rather than test recall.
Plain English
It's the first question an instructor asks to get a class discussion going. It's worded so students have to think and explain, not just give a one-word answer.
Context Anchor
Seen in flight instructor training when learning how to run a guided discussion instead of simply lecturing.
Derivation
"Lead-off" comes from the idea of leading off, or starting, a sequence — the same usage as the lead-off batter in baseball, who is first in the order. The question that goes first and opens the discussion.
Why Pilots Care
A well-chosen lead-off question draws out what students already know and keeps the discussion focused and participatory.
Intuition Check
A lead-off question is not the same as a leading question. It should open useful thinking, not hint so strongly that the student only has to guess the answer the instructor wants.
Example Sentence 1
The instructor began the weather lesson with a lead-off question: "What factors would you consider before flying into an area of forecast thunderstorms?"
Example Sentence 2
Using a strong lead-off question revealed the students' existing ideas about lift before any new material was presented.
