I have STACK up an running successfully. only problem is that i am not any good at authoring questions. anyone have a guide on authoring STACK questions in the works? I know there is an authoring guide on the STACK wiki but it really assumes you know what your are doing already which I for one do not.
Hope this helps,
Chris Sangin, the creator of stack, is involved in a project called FETLAR, which is about building up banks of assessment question as Open Educational Resources. Building Stack questions is part of FETLAR, and I think it is mostly aimed at Secondary/High School level maths.
very interesting. thank you for the lead.
