STACK (www.stack.ed.ac.uk) is a CAS-based plugin for Ilias and Moodle that allows randomization of mathematical tasks and provides feedback based on individual answers. It is a powerful tool for computer aided assessment and feedback, similarily in formative and summative settings.
The 3rd International STACK Conference was planned to be held in Tallinn, Estonia and hosted by the TTK University of Applied Sciences (TTK UAS). But due to the COVID 19 outbreak it took place in a virtual environment on April 27, 2020. (https://sites.google.com/tktk.ee/27-28april2020tallinnestonia).
