What should instructors observe during a stroke correction session?

During a stroke correction session, instructors should primarily focus on the technique and body position of the swimmer. This involves observing how the swimmer executes their strokes, paying attention to elements such as arm movement, kick, breathing patterns, and overall body alignment in the water. Proper technique is crucial for ensuring efficiency and effectiveness in swimming, as well as for preventing injuries. Effective stroke mechanics not only enhance performance but also promote a more enjoyable swimming experience.

While other aspects like swimmer's attire or the duration of the session might have their own relevance, they do not directly impact the immediate goal of stroke correction. Gauging other students' reactions might provide context about group dynamics, but it doesn't offer critical feedback for improving an individual swimmer's technique. Therefore, focusing on the swimmer's technique and body position is essential for successful learning and improvement during a stroke correction session.
