The 'resurrection' of this thread may be useful for other student divers about to begin training, or certified divers pursuing additional training beyond initial certification. There have been a number of threads on SB, including several sticky notes, regarding selection of the 'best' instructor. And, I am always intrigued by the variety of perspectives. I am also very much of the opinion that the student's perspective(s) substantively influence the outcome of any learning process.
This has been brought home to me over the past several months through participation in a non-scuba activity, somewhat simultaneously by coincidence, with a friend / acquaintance. The two of us have participated in a personal development process, begun at slightly different times (he several months before me), involving the same pair of professionals - essentially what might be deemed 'instructor' equivalents. We have had virtually the same types of exposures to the course material, and the same periodic interactions with the professionals. But, we have come away with very different reactions to the program and the professionals. At first, my friend was positive about the two professionals and, before I started the course, was quite enthusiastic about them. Over time, he has essentially moved to the opposite end of the satisfaction spectrum, and now complains that they do not listen to him, that they don't give credence to his comments / concerns, and he regularly voices suspicions that they are somehow trying to 'cover up' their inadequacies or hide something from him. On the other hand, I have had what I consider to be a consistently positive experience with them and the program, I believe that they are competent, caring, and communicate rather well.
From my perspective, the two professionals are the same, the difference is in the mindset of the 'students'. I don't say this to suggest that my friend is wrong, and I am right. it i possible that we could find our 'roles' reversed with a different course, or set of professionals. Rather, the bottom line for me is that there are often subjective factors that influence process and outcome in any learning / development process, including but not limited to scuba. And students / divers can have very different experiences with the same program / people. I am usually hesitant to criticize another instructor from afar, based only on the description provided by one individual student. That doesn't mean the individual is wrong, only that not every student is 'right' for every instructor, nor every instructor 'right' for every student. The revelation doesn't rise to the level of rocket science or amazingly unique insight on my part. But, it is a useful reminder for me as an instructor, and a learner.
