One initiative is to hold collapsed-timetable days once a term, when the whole year group gathers to debate topics. The last two have been on crime and justice, and asylum seekers and refugees.
The day starts with an ice-breaker. I set up a carousel with a ring of girls on the inside facing out and a ring on the outside facing in.
The girls are given a topic to discuss, such as different types of justice - deterrence, punishment, rehabilitation and retribution - based on discussions we have had.
They can spend about a minute talking to the person in front of them and then they shift round to the next person. It's great for creating a hubbub of noise that gives everybody the confidence to speak out without embarrassment.
We follow this up by dividing pupils into groups to make a presentation on one of these topics. The last session of the day involves role-play based on a crime case study where we have lawyers, a judge and a jury.
On our asylum and refugee day we used this final session for a formal debate, with motions such as: "Refugees are the cause of higher crime rates, discuss". Pupils learn the art of arguing on behalf of someone else and presenting in public
