Which step involves the instructor explaining the skill to the participants?

The correct choice is rooted in the instructional process of teaching water safety skills. In this context, the step that involves the instructor explaining the skill to the participants is indeed "Explain." During this phase, the instructor articulates the details of the skill, providing participants with a clear understanding of the technique, purpose, and any safety considerations. This explanation is essential for ensuring that participants grasp what is expected before they engage in hands-on practice.

In contrast, the other steps serve different purposes. During the "Demonstrate" step, the instructor shows how the skill is performed rather than explaining it, which reinforces the verbal explanation with a visual model. The "Practice" step allows participants to try out the skill themselves under the instructor's guidance, focusing on application rather than explanation. Lastly, the "Evaluate" step involves assessing participants' performance of the skill, providing feedback and adjustments, but it does not include the initial explanation of the skill. This structured approach enhances the learning experience and promotes skill acquisition effectively.
