Lets see, teaching OW, consulting OW manual. Gee, sounds like a novel concept. Unless you have the manual memorized and can quote exactly where the student can find the statement in their manual.
I've known instructors that have been instructors for a lot more than 6 years that still consult and refer to the OW manual, and not just PADI. Sounds like a solid approach if you ask me.
I still use my OW manual when teaching. Yes, I can PROBABLY quote most of it, but that doesn't replace using it when you're discussing questions in the class.
Through this discussion, I didn't see one thing ever come up. Although it is copyright infringement to photocopy a page (and yes, it is wrong even if no one sees you do it), no where does it actually stipulate that the questions have to be on the page the students turn in with the answers.
I have had many students turn in the answers written on blank paper to keep the original book clean and complete. A side benefit is that the book could be reused by a family member in another class.
I will agree that during a class when families would share a book it sometimes really showed who was and who was not spending enough time with the book.
There's two sides to this one. I think that any step that reinforces a bit more solid of an approach to instruction is fine. But I have to say that I've seen more than my share of CHEAP divers. I've never heard my skiing buddies whine about equipment and instruction prices like divers do.
If someone does their OW and then another 2,000 dives without additional instruction, more power to them. And if another person likes the guided aspect of scuba instruction, great for them too.
Anyway, I'm down off of the old soap box now.
Next person???
