These ideas have come directly from @heymilly and can be seen in her presentation on BYOD.
We have a class that values AKO, where we see ourselves as all being teachers. This really takes the 'stress' of as you are not the only one who knows. The class bubbles will just make this explicit to both our class and our buddy class also. They will be placed in our central 'cloak-bay' so it can be developed as a shared space and the expertise can be seen as a shared resource.
Developing 'What to do if…' charts: While we need to identify further areas as a class that we need to develop these in, I have begun by creating two. These are the two that drive me most crazy as the students struggle to manage themselves on these.
