Every lesson I teach includes visuals, lecture, hands-on opportunities, small group consultation (I actually tell my 5th graders to consult with a neighbor), experimentation, physical movement, and so on.
The fancy name for how we learn is called a "Learning Modality." There are many learning modalities, but they are all variations, or permutations, of three basic styles; visual, auditory, and kinesthetic (which can become tactile).
The lucky thing for us as riders is that our lessons or clinics are learning experiences that naturally incorporate all the learning modalities! Think about it: it's kinesthetic as we search for the right "feel," it's visual when our trainer shows us, and it's auditory as the instructor calls out corrections or directions.
I love lessons because they always involve auditory learning. The trainer talks while the student listens. And if the trainer uses an earpiece/speaker system, I am really in heaven as the the lesson is then piped directly to my brain. If you are not an auditory learner, you might find all of the trainer's "talk" distracting.
Lessons or clinics also involve a lot of kinesthetic learning as the rider must DO what the instructor says. This works best for me when the instructor gives a lot of oral directions, but for a true kinesthetic learner, you probably just figure it out the longer you ride. Maybe you get better and better at seeing that distance just by riding it over and over. Those naturally gifted riders are probably very much kinesthetic learners. Alas, I am not.
In many cases, a clinician or trainer will also demonstrate visually what they want you do by moving their own body in a sort of pantomime of what we should be doing. My trainer does this all the time as I watch from the saddle. If you are a visual learner, you probably like your trainer to show you by having them demonstrate from the ground like my trainer will do, or you like her to hop on and show you. You probably like to watch others take lessons too.
If you are a tactile learner, someone who needs to take notes or doodle while learning, you probably learn best by attending clinics or watching others participate in a lesson. I don't know if Sarah of Eventing in Color is a tactile learner or not, but I have been amazed before by her note-taking skills.
