It gives me great pleasure to report the successful use of STACK 3.0 over the last academic cycle.
We started using STACK in Birmingham last September with groups of 250 first year mathematics majors. Each week these students have worked on formative assessed quizzes consisting of STACK questions covering core calculus and algebra. A small number of minor bugs have been fixed, and a number of other improvements made to the software since then, but really it has been an ongoing and quiet success.
I am now confident that the current version of STACK is working well, and would encourage others to take a look for the next teaching cycle. Care is still needed to ensure sufficient server resources, and to optimise the connection to the CAS (which can be slow) and we are working on a number of improvements here.
A demonstration server is now available on http://stack.bham.ac.uk/moodle/
Note that the "demonstration course" is freely distributed with the STACK code, so all these questions are available for potential use with your students. This includes about 450 randomly generated calculus and algebra questions which have been converted to STACK 3.0 and arranged into quizzes.
I know from experience that we have not made the full use of the features STACK offers. Indeed, we have been quite modest in our own use up to this point. That said, I'm very happy to receive suggestions for improvements or feature requests. We have development plans available online at https://github.com/maths/moodle-qtype_stack/blob/master/doc/en/Developer/Future_plans.md
Please post any bug reports or feature requests online at https://github.com/maths/moodle-qtype_stack/issues or send me an email directly.
I'm very keen to find out who is really using STACK, so please send me a message if you make use of this question type. I'm also always happy to receive contributions to the system itself, to the documentation etc.
I'm very grateful to those colleagues who have written code, translated the language packs, tested the system and encouraged me to continue this project. Thank you. I'm now sure this is a very worthwhile addition to the online assessment potential of Moodle, and I'm very glad that in Jan 2012 I decided to commit to the question type as part of the Moodle quiz.
