I often tell people that my strength isn't teaching, per se, it's my ability to have a relationship with my students. Part of that relationship is getting them to do what I know they need to do, and as any parent or teacher knows, this involves a fair amount of manipulation, for their own good. I don't mean pathological manipulation, I mean healthy manipulation.
I first wrote about outsmarting teenage boys here. I had another episode with a boy I'm tutoring and I was very proud of myself.
Me: I need you to read your writing aloud so that you can catch your mistakes.
Him: That is too embarrassing. If I do that, I will be embarrassed.
Me: Is that a picture of you in a TeleTubby costume on the wall?
Him: Fine, I'll read it.
This is what I mean by "healthy manipulation." We could have wasted the whole session arguing. Instead, it took 20 seconds, he caught his mistakes, he realized how to edit his own writing, (and I think he liked the attention of me noticing that photo as well).
