This thread is really revealing and possibly just a bit grating. Now don't start to bristle, because what it reveals to me is not something necessarily linked to diving, but education in general. You see, I teach in Texas and there is a bit of a teacher shortage. To alleviate that dilemma, our legislature has passed a law allowing persons to become certified as public education teachers. All they need is a degree (in just about anything), pass a short series of online "modules" or courses, and then pass a proficiency exam in the area in which they desire to teach. Presto! They are "teachers".
What's ironic to me is that every post on this board so far says that is inadequate for scuba. We desire and even demand that instructors have experience, advanced training, and good teaching skills so that students get the most from their training (as it should be). But then our society will condone and even promote the practice of "certifying" untrained people into the ranks of professional educators, and they will teach our children from kindergarten to grade 12. Amazing.
Thanks for allowing me to vent for a bit. (breath in....breath out....breath in...breath out...)
sigh. I feel better now. : ) Have a great day!
