We've just run a workshop on looking at STACK (and also NUMBAS) for maths e-assessment going through the author quick start guides to give staff a feel of what is possible/doable.
Is there any general sharing of STACK questions? When looking at NUMBAS, there is a very public repo of questions that allows a question bank to be built up quickly and existing questions to be expanded: this would be great for the introductory maths and formative cases that would initially be exploring. It would be great if people do want to share STACK questions in a similar way, and obviously we'd encourage staff here to reciprocate!
