Me and some colleagues are starting to work on adaptive diagrams in JSXGprah for STACK questions. I understand that this might be relevant to several STACK users and I would be happy to understand what other people are doing with this, what progress might have been made for successful implementation or get new ideas to try to implement.
Currently we are looking specifically at using JSXGraph events and states to test graph sketching skills in a number of ways but second in the list is looking at dynamic geometry apps that work for secondary school style geometry questions, but could also be applied in other contexts - I imagine for example many questions in mechanics were getting the right diagrams is an essential component and a similar approach could work.
If anyone is interested in sharing ideas or working in collaboration I welcome comments in this thread. I will soon comment myself with some examples.
