How to boil an egg

Every now and then our team shares ideas about their teaching - things that have worked and things that haven't. One of the problems I'm often faced with is wanting to make learning experiential but being limited by teaching large numbers of students (50+), in a short space of time (1 hour) in an inappropriate teaching space for experiential learning (a lecture theatre).

One of my particular frustrations was (is) trying to teach presentation skills by telling rather than by doing (because of the limitations mentioned above). This isn't anything ground breaking  but here are a couple of slides I've used recently to try and get students experiencing what it's like to present from a text heavy slide versus a visual slide. I get them to pair up and have a go and then take feedback on how they found it.

Does anyone else have any bright ideas?
