Tutorials STACK

STACK Video-Tutorials


STACK is a task tool with which closed as well as open mathematical tasks can be implemented. It is possible for STACK to generate tasks randomly and provide students with differentiated and adaptive feedback.
In this course you will get to know STACK and learn how to create your own tasks with the help of numerous video tutorials and corresponding sample tasks.

At the very bottom you will also find a STACK wiki created by us, a PDF short manual for the tool and a link collection with further support for STACK and Maxima. You will also find the "playground" where you can try out STACK yourself and create your own tasks.

This course is completely public and accessible without login. However, to use all functions without restrictions, an account for the Moodle of the Ruhr-University Bochum is required. If you don't have an account yet, you can create one free and easy by following this link.
