STACK is a computer aided assessment system for mathematics.
The current version is integrated into Moodle.
I know from the volume of email I receive that STACK is being widely used, in some places by large numbers of students. E.g. up to 4000 users at a single site. However, while companies have data on customers, open source software is available for free download. To get a better idea of the extent to which STACK is being used with students I would invite you to take part in a short survey:
I appreciate the value of your time, but it would assist me greatly in making a case for future funding to support the development of STACK if current users could provide me with some details of their usage.
For colleagues who have looked at STACK but decided not to make use of it, I would very much like to know why they have chosen not to do so.
In releasing the STACK computer aided assessment system we invited colleagues to join the STACK online community
Those people who use, or are interested in, STACK are again invited to join and contribute to this site.
If you would like to contact me directly about STACK, rather than completing the survey, then please feel free to do so.
