I have met all sorts of instructors in my career. Majority are less tough nowadays than the 'ex army' of 40 years ago!
I love teaching and have ben told I am very good at it. Some pupils need a kick up the butt whilst others need encouraging and even if it has been a bad lesson all should leave the arena feeling that something has been achieved even if it is how not to do something!
I was working full time with horses and had the chance to go on a course with an Olympic Event trainer.
The woman who arranged this was competing at Badminton so, basically this was her chance of getting a tune up and the rest of us were paying for it.
Much to my amazement instead of being given a time for instruction it was an all day thing with 14 horses in the arena at the same time. It was ridiculous, overcrowded, all sizes of horse, all experience of riders and all different experience with the horses. I was riding a green mare that had done very little.
The first morning about 6 people left the arena in tears. Two came back in the afternoon, one left again as did two other different people.
The instructor was good, he really knew his stuff but was rude, arrogant and determined to end up with only a few riders in the arena.
I have always been stubborn and was going to get my moneys worth and no matter what he called me, screamed and swore I was not going to either cry or leave. The only person who got any praise was the Badminton rider.
One poor woman kept leaving and coming back. She had a very nice 15.2 h grey mare that was a bit beyond her ability. We were doing some grid work and the mare was not going an inch. He yelled and the woman left in tears, leaving her horse. He put the Badminton rider up on the horse and she did no better and the mare was refusing to go over the three trot poles into the grid. (At least this was getting her yelled at!)
I turned to the girl next to me and remarked that I thought I knew what he was getting at.
That man must have ears of a bat because he yelled at me "If you think you can do better, get on the horse!"
I dismounted and handed my horse to the girl next to me and vaulted onto the mare. The stirrups were to small for me, so I crossed them in front of the saddle. The mare was not moving away from the leg so I cracked her two with my whip. She shot off at a fast canter and I brought her back to a trot. Going into the poles she was backing off so I cracked her again. The result was that she scrambled over the trot poles, knocked the first X rail, was going to stop at the bounce so got another crack, went over the bounce and hit the fence out of the grid.
I was hollered at and called all sorts of names. I turned and said "Well, I was taught that if you put a horse at a fence it either went over it or through it but never stayed the same side or went around. Now, she will do it correctly."
Before he could say anything I took the mare back to the grid and this time she was trot, trot, trot, bounce, bounce, bounce, one stride and them two. She did it beautifully, no hesitation or thought about running out. Ears pricked and forward going.
I dismounted and handed him the reins and remarked "Well, I think that is what you wanted." and remounted my horse.
After five days of this type of instruction we had a talk. At the end of this he came to me and said "You have made more improvement than anyone else."
I returned with "Well, had you once given me a world of encouragement I am sure I would have improved more."
To be a good teacher is a gift. It is knowing when and what to yell. It is understanding the temperament of rider and horse. It is an ability to when things are not getting through, being able to look inside oneself and put whatever in another way.
Many top riders will do courses but it does not mean they can teach!
I do admit to yelling and my voice carries! A rider concentrating often needs something to break through the concentration at that particular moment and a good voice will do that!
As I said, even if a ride has not gone well all should leave realising that although it was not the best things were learned.
