Do I doubt the modern educators capacity to adopt new technologies in the class room? No. Many do it very well and with wonderful results. Does the class room need to change so drastically that it is unrecognizable to a time traveler? No.
I also don’t think the parable was just a demonstration. He used the parable to create a dichotomy of schoolers and yearners. My point is, if the chapter is about changing the philosophy of the education system, the parable need not put such emphasis on technology, creating a false dichotomy, then making the “schoolers” seem out of touch for nor immediately embracing technology, and the “yearners” out to be some enlightened educated group.

Your list of qualities you want to avoid reminds me of an episode of “How I Met your Mother” where the main character is fretting about teaching his first architecture lecture. He’s going back and forth about what kind of professor he wants to be. He’s over thinking it in a comical sitcom type of way. He gets up in front of the class, and he has thought about it so much that he starts fumbling and comes off as… fake I guess is the best way to describe it. But, he is saved by the fact that the class he just embarrassed himself in front of wasn’t the class he was supposed to be teaching. He has to run across campus to his actual classroom, and he is so late and flustered that he doesn’t have time to overthink; he just acts himself and does fine. I think being aware of the qualities you want to avoid is a great thing. Self awareness is a great quality. Having a this conversation with yourself about what kind of teacher you want to be is spectacular. I guess my point is, don’t let the list consume you. You’ll do great.

I’ve had conversations with a few people about professional distance. Each of those people seem to have found what works best for them. Some have their students call them by their first name, dress very casually, and really get to know their students on a personal level. Some make sure they wear a tie to every class session because it helps them feel as though they have set themselves apart from their students.I think it’s finding what you are comfortable with and what works for you. The hardest part, at least that I’ve found, is what I’m comfortable with and what works for me doesn’t always line up with the teacher I want to be. I think, like with anything, it’ll take time to hone in the craft of teaching. Maybe one day I will be the teacher I think I should be. For now, however, I’m sticking with what I have found works for me.
