Had all this effort been positively utilised the student could have been an instructor by now standards permitting
Until yesterday, I never heard any DM or DM trainee use the phrase “my student,” first or otherwise.
OP is not training to be an instructor. Even when he finishes his program, he still won’t be qualified to teach.
So no, “all this effort“ could not have been re-directed to make the OP an instructor.
That’s one of the friction points in this thread.
And, as I said yesterday, my criticism is aimed at the instructor, not the OP.
On the occasions I’ve had DM candidates assist with my courses, it has never occurred to me to have them introduce skills. Why? Because they are present primarily for their own preparation to be divemasters and secondarily to help the course run more smoothly. Having them teach would not help them prepare to be a DM, because DM duties don’t involve teaching. Having them give pre-dive briefs, supervise gear setup, and helping herd and pay attention to divers are relevant to their future employment as a DM, so I do ask them to assist in these areas.
I can’t think of a valid pedagogical reason to have a DMT perform the teaching tasks the OP was assigned.
If she had a reason, she should have prepped him to explain the performance requirement and relevance of each skill, told him what errors students are likely to make, told him how to spot and constructively correct those errors, and told him how best to position himself to provide assistance or reassurance if the student gets flustered or panics. These are all instructor concerns that DM candidates don‘t need to know to become effective DM’s—whose primary job is to lead qualified divers..
From where I sit an ocean away, she put him in an untenable position, didn’t advance his preparation to become a DM, short-changed her students, and created a false impression that providing scuba instruction doesn’t require much special preparation, which is sort of true only when everything goes right.
