Plain English Meaning
The first part of a lesson, where the instructor tells the student what they're about to learn, why they need to know it, and what the lesson will cover.
Full Definition
The opening segment of a lesson that establishes contact with the learner, gains attention, defines the objective, and previews the key points to be covered. In aviation instruction, the introduction sets the stage for learning by orienting the student to what will be taught, why it matters, and how it fits into their broader training.
Context Anchor
Seen when an instructor plans or presents a ground lesson, a preflight briefing, a flight lesson, or written training material.
Derivation
From the Latin 'introducere,' meaning 'to lead in.' The introduction literally leads the student into the subject — it brings them inside the topic before the main begins.
