There is a reason why the person that leads the WT Study is called a "Conductor" and not a teacher. He merely follows a set course of "study". Don't think outside the box Brother. Stick to the print. Even an orchestra conductor has more latitude with "interpretation" than a WT Conductor, but he still needs to stick to the notes.
In the old days, the Theocratic Ministry School Overseer at least got to teach speaking and oral presentation skills, that was until the Leadership--in their infinite wisdom--decided to get rid of Public Counsel. Everyone's a Winner! Woo-hoo, no matter how much you suck the TMS Overseer still needs to say "Good job! Atta-brother/sister. No sit down." We can't risk damaging someone's "self-esteem" by actually suggesting ways to improve. God knows it's hard enough for the TMS to consistently get the publishers to keep their commitments. It's curious the school is so stressful for so many since it's really dumbed down. Most of the friends would completely flounder if they actually tried going to a real college or university! ... but I digress ...
The Bible Reading even used to allow some opportunity for expressing research and individual insight and application, but again, the Leadership--in their infinite wisdom--got rid of that too: "Just read the ink Brother. Don't comment. No we don't care what you have to say. No original thought is required or even encouraged."
Some KM parts had a little wiggle room to actually teach, but not much. They kept the timing constraints so tight that you couldn't really squeeze much in that wasn't in the article. More and more they became a mini-WT type of setting:
Ask questions, regurgitate answers, call it food. Which brings a thought to mind, isn't pre-digested food usually referred to as VOMIT! Mmmmm, gotta' get me soma' that! Yum!!! - Mt. 24:45
Please, sir. I want some more!
