What best defines the act of demonstrating how to do something in training?

Demonstration is the act of showing how to perform a specific task or skill, which is a key component of effective training. This approach allows the trainer to visually convey techniques and methods, enabling trainees to see the process in action. By demonstrating a task, the trainer provides a clear example that learners can emulate, facilitating a better understanding of the procedural aspects involved.

In contrast, while presentation involves sharing information, it may not involve the practical showing of how to do something. Practical skill evolution suggests a focus on the progress and development of skills over time, rather than the immediate act of showing. Discussion typically involves conversation and exchange of ideas, which may lead to understanding but does not provide the direct, visual instruction that a demonstration does. Thus, demonstration is the most fitting term to describe the act of showing how to perform a task in a training context.
