For my presentation I kept it to what I had experienced in the classroom and tried to back it up with an example, avoid making sweeping statements. Anything you feel you've learnt even if that is from observing someone else I would talk about it. I kept my points breif to try cover more, if that makes sense.
I talked about inclusion, behaviour, safeguarding, classroom layout, the kids work mentality, self reflection... I even stuck in about how my confidence has grown and how I had to teach my class a dance routine, def try fit in somewhere something only you will have! You will have so many experiences and formed your own opinions, convey them well and you'll do great!
Phonics is def a good one to talk about, link that in with children who have english as a second language, their big on that!
They breifly ask about your degree but that will be fine, my undergrad is in economics, couldn't be any more different lol just show your passion for teaching and you'll be fine. they do ask why you choose brunel though! Which was easy for me being a past student so played that up! very local, only 10min drive, you moving out? Brunel your first option?
You'll have to let me know how you get on!
