Hi Mary,
So sorry for the delay in getting back to you on this one! We had a little discussion about it with members of the OpenLab’s Community team. This is definitely an interesting question and approach!
The consensus within the group over here was that they have indeed evolved their course sites over time, though not perhaps to the extent you describe – for instance, making things more prominent as they are needed, then filing them away (so to speak) after that part of the course is done. We recommend using categories, as this makes it much easier to move things around – and, obviously, ensuring students understand what’s happening to avoid confusion! 🙂
We have also seen people work with their students on building out sites as a course project – one great early example, unfortunately no longer live, was a student-developed guide to City Tech and the local environment. They built it privately then did a big reveal with a launch party!
But we couldn’t think of anyone doing exactly what you’re talking about – do let us know how it’s going! 🙂 BTW, this is exactly the kind of thing we imagine people being able to discuss on the Community Hub, so we’re looking forward to getting started on building that…
Charlie
