I'm an NQT and wasn't strict enough with this Yr 10 group at the start and I am still suffering for it. The naughty girls think I'm a joke and the good girls have despaired of me. The system I have been using involves telling students to get their planners and put them on my desk for a warning, then this goes to a detention if I have to speak to them again, This works fine for most of my classes but I'm still not on top of this one Yr 10 class who play me up so much I lose track of whose planners I have and it disrupts the class so much to be constantly asking them to get planners which gives them an opportunity to flounce across the class and take forever looking for it etc. SO I am considering changing my approach and having all of their names up on a flip chart and adding ticks for good work and crosses for any disruption (ticks - merits, crosses - detention etc). I think this will help me to keep track during the lesson and means I am in control of reporting the transgressions not worrying about them sneaking off with their planners at the end. However, I'm quite nervous as my HOD has advised me not to change tack as he wants the whole dept to use the same system. I'm also worried if it looks a bit primary school and won't work for them. However, I'm at the end of my tether and I'm really failing them as a teacher, so I'd really appreciate your thoughts on this and any other advice you may have. Thanks!
