I have been in schools where the SAME disruptive year 11 or year 10 class goes suddenly quiet and respectful when a certain teacher walks in. I am doing long term cover and I have seen and experienced this many times. To be honest, I am quite easy going, but fair. I think my problem might be not enforcing my seating plan each lesson, but my classes had 6 different classrooms and I found it so hard to keep creating a seating plan for each one, so I let it slide. Then the year 10s and year 11s had lost respect for me so simply sat where they liked and it became too hard for me to try and re-introduce another seating plan. It was becoming farcical because of all the different class room layouts. So I eventually gave up on it. So then of course had behaviour issues. I know that I am rubbish at enforcing my seating plan and I have let it slide, so that it is hard to get the pupils back into it. The pupils come in and sit where they like and I find it exhausting to keep reminding them, so then I let it slide. It was really depressing that I couldn't then control the class because of this. Teaching my year 11s from the front of the class became impossible so then I just gave the work out in groups and let them get on with it. What other options are there if you are in different classrooms all the time?? I didn't have enough time in the school day and stay late and re-do the seating plans properly and evenings I was too tired. I have a morning and after school run myself, so had to leave at 4.30pm each day. However, it is deeply demoralising to see this happening. I feel depressed that I am not able to control the behaviour like some other teachers who get so much respect. I have excellent subject knowledge, so I know that is not the problem. Any suggestions please?
