I am wondering if anyone can suggest any strategies for dealing with students who are particularly unpleasant - as in, will often go out of their own way to try and knock you down a peg as a teacher and make it appear as though you don't know what you are talking about. I teach in an FE college and I had a student who needed to do a level 3 maths course (despite getting an E grade in AS Maths and thus already having a level 3 qualification) which I presume he needed to do as he was only doing two A-levels and an enrichment programme, so that he could continue at college. It was my first year teaching this course (as well as teaching full stop) and it also a very new course, which has meant that I have had to try and improvise more and rely on the limited resources available. This student was frequently badly behaved, and sent me a sassy email when I emailed his tutor about it. In class he often made cutting remarks, tried to insinuate that I didn't know what I was talking about, deliberately ask awkward questions to try and trip me up, tried pointing out flaws in points I made and claim on more than one occasion that I said something inappropriate (even though the things I did say were more meant as light-hearted jokes). He also used his phone rather a lot in lessons once he had completed the work (classroom management is really not one of my strong points). Overall, he was a nuisance to teach, partly because he was actually completing all the work, never missed a lesson (and so I couldn't think of any plausible reason to punish him other than him being a general ****) and he came up with some good points in lessons which I genuinely liked. He is on course to achieve an A grade in that course. I just didn't like him or the way he said things in such an abrasive way. He even called me an awful teacher at the end of the year (although attempted to be subtle about it by pretending to go back into the classroom to pick something that was left behind). I wish I had taken a more firm line with this student earlier on in the year but I just kept telling myself it wouldn't be long before I'd no longer need to teach him again (not a good approach). Teaching in my first year alone has been a very daunting and emotionally challenging experience, and having to deal with this student has further had a negative effect on my confidence. I am aware that as a first year teacher I will have gotten a lot of things wrong (and I don't feel I did the course justice) but this sort of low-level disruption does not help. However, I am aware that this sort of student is a standard affair and I need to devise some strategies for dealing with this sort of behaviour. What can you suggest?
