Plain English Meaning
Practice that targets one specific skill you are not yet good at, performed with full concentration, with someone or something giving you feedback so you can correct and improve each time.
Full Definition
A focused, structured form of practice in which the learner works on specific, well-defined skills at the edge of current ability, with full attention, immediate feedback, and repeated correction aimed at measurable improvement.
Context Anchor
Seen in flight training discussions, especially when an instructor helps a student improve a weak skill instead of simply repeating the same flight task over and over.
Derivation
From Latin 'deliberare' meaning 'to weigh carefully' or 'consider thoroughly.' The word signals that this kind of practice is thoughtful and intentional — not casual repetition.
