I'm not a "Professional educator" nor do I play one on Television. But I DO teach SCUBA to HIGHSCHOOL kids, (Prerequisite: NAUI Instructor Cert and a full stock on asprin)
As far as adding to the course, I found myself adding "Dog" to the end of many topics and when I ask if everyone has understood, I substitute "are ya feelin' me"? ie. Ascend no faster than 30 feet per minute or no faster than your smallest bubbles, Dog. Are ya feelin' me? Praise is accomplished with "Dog, that's pretty dope".
All this can be learned in my new NAUI EBONICS FOR DIVE LEADERS course. So, while you're chillin', consider learning how to speak "teenager", take this course and you too wil be able to "throw the mack down" on your lectures, dog! Get down wit yer bad self.
We also offer "Diving for Homeys", One homey brings in a bunch of other homies in a relaxed innercity environment, The instructor using the techniques learned in NAUI EBONICS FOR DIVE LEADERS will be able to slash through the language barrier without a strap, subjects include "reef tagging".
DISCLAIMER: There is no such thing as a NAUI EBONICS FOR DIVE LEADERS, so for those who were actually thinking of this specialty (as there inevitably are), YO perish the thought! It's all in jest, DOG!
