Here's the thing ... do students understand why they're doing these drills? Do they do it just because they have to in order to pass the class? Or do they comprehend the reasons why these skills are taught ... and why it's important to get comfortable doing them? OW students lack context ... and the only context they'll have once class is over is what they got in class. That's the foundation upon which their skills will be built as they continue diving.
I agree with you straight up, they lack context. However, you can build in context in how you teach. Not in drills, but in artificially creating environments where they need to use certain skills. See if there instinct is correct.
I had a student last year struggled with mask clearing. We worked at it and eventually she got it OK ... but you could tell she dreaded doing it. I made her do it again and again. After a while she got mad at me and asked me what I was expecting her to do. I told her I expected to see her clear her mask like it was no big deal ... because after this class was done if she had to clear her mask I wouldn't be there ... and her buddy might not be either. Next time I signaled for her to flood her mask she pulled it off completely, put it back on, cleared it, gave me an OK, and then gave me a one-finger salute. I figured now she's ready ...
Funny story, I had the same thing happen with more then one of my students. One of them was so bad I had to spend a lot of extra time with him off the clock. When he finally figured out his weakness and how not to suck in water through his nose (his particular issue) all of a sudden, he felt comfortable.
Thats the sort of instruction we need today. We need teachers who are willing to take the extra step and make sure students are fully prepared for the great big ocean out there. Its sad to say, but in all honestly, there are a great deal of divers out there who probably shouldn't be diving. Just like there are millions of DRIVERS who shouldn't be driving, yet we still have hundreds/thousands of car accidents each day.
