I teach at high school and all in all my classes aren't too badly behaved. I try to make most of my lessons interesting and fun for the students and it seems to work in most cases. However I have been having trouble with one class who just talk and talk whatever the weather. Last week I flipped at them and said if they continued to behave badly we would just do a tests, dictation or other boring material instead. I don't want this to be an empty threat. I asked my co-teacher and she said the only past English papers they had been used or were 'unavailable'. I'm wondering if anybody has any 'boring but worthy' material' I could use next time they start playing up?
