What do many teachers prefer to do prior to going on course?

Many teachers prefer to observe different shots prior to going on course because this practice allows them to gain insights into how various shots are executed and to analyze their effectiveness in different conditions. By observing shots, teachers can better understand the nuances of the course, including which techniques are beneficial for specific holes or challenges that a particular course presents. This observation can help in teaching students the finer points of executing shots themselves when they are on the course.

While other options may provide value in their own contexts, they do not offer the same direct analytical benefit. Practicing putting can enhance a teacher's skill, but does not necessarily help them understand how to adapt their teaching to the course's challenges. Reviewing the course layout is also important, as it provides a strategic overview, but it doesn't focus on the practical application of techniques. Consulting a coach can be helpful for personal improvement, but it may not be specific to understanding how different shots play out in the context of the specific course.
