I am having difficulty getting full attention from the class when I need it. It was slipping last term and I see it still slipping. They are often fairly quiet but there is a bit of chat and there is a definite feeling of even if they are quiet, they are not paying attention or thinking through what I am saying. I have tried a lot of things and I am tired of talking at them. I teach secondary (fifteen-year-olds) and they KNOW they need to listen. I work in a good, private school with good behaviour and supportive parents. My usual routine is give them a warning, a reflection on their behaviour, then a signed reflection, then an afternoon detention (this is a big deal in our school). I am tired of telling them what I am looking for. I want something simple and workable day-to-day as I also feel swamped with work at the moment. I am thinking that reporting students on, or meetings with parents could help, particularly for ones who in consequence of not paying attention, have poor grades. I am also thinking of less whole class teaching time and giving them more work at their desk so that I do not wear out their patience by talking at them frequently. (I am wondering if I tend to talk too much.) Advice is much appreciated!
