Watch with attention
A demonstration gives a learner more than a sequence to copy. It shows pace, preparation and the small checks an experienced person makes almost without comment. Asking about those checks can reveal the reasoning behind the visible movement.
Practice with feedback
Repetition matters when someone can notice what changed and explain why. Feedback helps a learner connect the outcome to the decision that produced it. That is different from simply repeating a task until time runs out.
Build responsibility gradually
Workplace learning needs appropriate supervision and a clear understanding of what the learner is ready to do. Confidence is useful when it grows alongside competence, not when it replaces a question that should have been asked.
