LF, do you not believe that people learn differently or individual personality traits that produce individualized learning results? Take the Myers Briggs test as an example.
I do agree with the video on learning in terms of how vs. why. The how can be explained though visual, auditory and kinesthetic means but the why is always the same which is meaning. I always remember the how, which ever way it is demonstrated but it is the meaning that attaches the information to the larger network. Once a piece of information is fitted with an overall understanding, it becomes locked into memory. But memory and learning are not the same thing. Learning is the acquisition of information and memory is the storing of that information. Things can be learned but immediately forgotten.
Ghost, I agree that there are aspects like these that can make learning easier for everyone or more difficult for everyone such as fear, frustration, disappointment, impatience and misdirected ego. But that is not an indication of personal learning styles.
Learning styles, Myers Briggs, Intelligence areas: Those are the negative emotions, which give rise to hormones that make learning difficult. Yes, avoid those, but more importantly, there are positive ones you could focus on and encourage. Positive ones triggered by appealing to the students personality and intelligence areas, success, and by the student enjoying being in his or her milieu as it were.
As to technique and skill, maybe look at something other than skiing. A martial arts student can demonstrate a hook punch, and in terms of what's moving where they have it. It won't likely be a good enough punch to be deadly or break someone's jaw most times they use it. They have it, but they still haven't mastered it because they haven't mastered the skills to put all of the available power, behind it. They haven't coordinated the flow and timing of energy through bone, muscle, sinew, etc.
