It's not even that. She says - very unconvincingly mind you - that she will get crap grades and it's all my fault
I can totally understand how you can take that to heart - I would certainly affect me very badly if anyone said that sort of thing to me. But the truth is that if she gets bad grades, it will be
her fault for not studying, not engaging with the subject - basically, not caring about her own education.
I guess everyone deals with things in different ways, but as a teacher you cannot afford to let the students hurt you like that. I don't think you should be upset or hurt. I think you should be angry.
I mean,
how dare these kids, who you dedicate so much time and effort to, treat you like that?
How dare they blame you for their own failings in attitude?
Feel confident in yourself, and what you're doing, and be perfectly happy to be angry if the students don't respect you. Okay, maybe that's not your personality - but teaching is a bit of a performance, so act out the part of a hard-bastard teacher if needs be.
Thinking back on my own school days, the teachers who I ended-up having the most respect for were the ones that, as a 1st year, I was most scared of. They were fair, but very commanding. By the time I left, I respected them - but even then wouldn't dream of stepping out of line with them.
Okay, I know that I have it very easy - I teach at a university, so I don't have anywhere near the hassle from the students that school teachers get. But, for what it's worth just this afternoon I was teaching a course that I've been doing for a few years now.
They are a good bunch, but quite boisterous. The first time I taught them I found it quite intimidating - I really didn't know how to cope with them. But in the few years since then I've gone into the lessons knowing that they're going to be boisterous.
As a result, I've gone in with a rather more assertive attitude than normal (which isn't my usual character at all) and it's worked really well.
Sorry for such a long, boring, rambling post, but let me boil it down to the following:
1. Be prepared to be a dominant personality - if it's not you, then act. Teaching is a performance anyway, so why not make out like you're the most important person in the room? And what difference would it make if a student was missing from the room? What difference would it make if you were missing?
2. It may be your job to educate the students, but part of the deal (a very big part) is that the students have to engage with the process, too. If they don't, then on their heads be it. Is it your fault that they cannot plug in learning like in The Matrix? No. You can only show them the Fountain of Knowledge - if they choose not to drink, that's up to them. If they die of thirst later on, it's their fault, not yours.
And finally, be assured that the there are a great many of us out here who really respect you for being a teacher - it's an amazing job, done by amazing people. Just like you.
