Hi Kathy,
Thanks for sharing your draft conceptualisation tool. I have done something similar with children to visualise and enact the workings of a city. It was helpful for the children to have a 'menu' of operations / movements / meanings. We used projected images and maps of the city in question (London) to visualise and identify the elements of the system and to create the menu.
Having the menu supported their thinking about the 'construction' or 'coding' of the elements and interactions of the system (city) they where trying to recreate.
I like the idea of using an online environment to document the system decisions. It creates a usable record.
Thanks for your ideas!
Kindly,
Claire
