If at some point the teacher finds him/herself searching for a way to attract attention
This line caught my attention because the best teachers I ever had taught me new ways to see and were able to make things that I once thought boring interesting. I can't imagine that they didn't consciously or unconsciously put a lot of thought and effort into communicating their topic (and passion) in a way that first drew me in and then drew out my creative engagement.
And yet, there is something true in what you are saying as well. I wonder what the difference between searching for ways to get attention as a sign of trouble and searching for ways to get attention as a sign of excellence? Any further thoughts?
