Instruction requires skills that go beyond teaching the name of a skill on a checklist. As my instructing skill grew, here were the most valuable improvements I made.
- My explanations prior to demonstrating the skills improved. You absolutely do not want to be babbling too long--it is counterproductive. You do, however, have to say the right things, and you have to learn what the right things are. For example, my ability to teach mask clearing improved when I switched to neutral buoyancy instruction, with students horizontal. I learned to make the point that the bottom skirt of the mask has to be the lowest point, with the mask perpendicular. I had never heard anyone say that exact phrase before, and it made a world of difference in student performance.
- In all skills, having seen just about every way a student could screw it up allowed me to make rapid diagnoses of what needed to done. As a new instructor, I sometimes watched intently to see what was wrong; with experience, I could see it and correct it immediately.
- I learned patience with certain problems. For example, when students are first in the pool, you have them inflate the BCD and swim on the surface. In some cases, students feel like the tank is throwing them around. They keep losing balance. What to do? Don't worry about it. It's a problem that solves itself pretty quickly.
- With technical diving instruction, I learned that some skills (like valve shutdowns and holding decompression stops) take a long time to master. I learned to just keep giving tips and assuring the students that they were going to get it down, so stop fretting too much. I have confidence in you, now you have confidence in you, too.
