What would be most beneficial in helping a teacher determine the starting point for on-course instruction with an experienced player?

Observing the student playing is the most beneficial approach for a teacher to determine the starting point for on-course instruction with an experienced player. This method provides immediate, real-time insights into the player's skills, strengths, and weaknesses. By watching how the student interacts with different aspects of the game—such as swing mechanics, course management, shot selection, and problem-solving during play—the teacher can gain a deeper understanding of the student’s capabilities and areas that may need further development.

This observation allows the instructor to tailor their teaching strategies to the individual player’s style, rather than relying solely on assessments or equipment analysis, which may not provide as comprehensive a view of the player's current performance. Furthermore, by seeing the player in action, the teacher can identify specific situations that challenge the student, leading to targeted and effective instruction that enhance the student’s overall experience and growth in the game.
