You probably devoted little, if any, attention to individual student differences. Part of the training required them to observe several lessons before they actually taught their own class. One instructor candidate seemed especially puzzled after a day of observation. She reported that she had seen three instructors teach first-time skiers and each of them taught something different. Not only that, but none of the lessons were the same as those she had learned in training.
Most instructors recognize that every ski lesson is unique.
Even when you try to copy lessons, they never turn out the same. I asked the candidate why she thought these lessons were so different, and her response gave me food for thought. She said she thought the instructors were teaching what they found most interesting. Whether this was actually the case, we may never know. As you gain experience, you learn that there are a number of ways to present content.
