There is now a staff user guide for Dewis, which will help you get to know the system and set up assessments (note: it does not cover coding questions).
The Dewis e-Assessment Sytem was developed at UWE to allow sophisticated generation and automatic marking of mathematical and statistical questions (though it can be used in other ways). It has been used for assessment in Mathematics, Statistics, Business, Engineering and Computing subjects, among others, both at UWE and other institutions.
The guide includes links to further information to find out more about Dewis and how it might be used in your subject.
If you have any questions, please contact firstname.lastname@example.org.
