The Stack of Activities for Teaching Computer Science

Teaching computer science with abstract lectures? Boring! We prefer active learning methods. That's why we created the Stack: an open-source collection of teaching activities for understanding and practicing CS concepts.

Each activity in the Stack features a thorough description, printable handouts, and supporting materials for teachers to easily use in their classes. For free.


You can browse the full list of activities. Or just have a quick look at our flagship activities:

Contributing authors

The Stack was conceived and is maintained by Valdemar Švábenský, a member of the Teaching Lab community at the Faculty of Informatics, Masaryk University.

However, the Stack wouldn't exist without the significant contributions of other Teaching Lab members, especially Martin Ukrop, who laid the foundations with his awesome Encryption modes activity, and Ondráš Přibyla, who shared his great teaching experience with us.

A big 'thank you' goes to the authors of the activities (in alphabetical order): Bibiána Ťureková, CSIRT-MU team, Jakub Žák, Jan Horáček, Jaroslav Čechák, Karel Kubíček, Lukáš Daubner, Martin Macák, Martin Ukrop, Matej Troják, Michaela Pokludová, Phillip Abramson, Radka Cieslarová, Štefan Bojnák, and Vlasta Šťavová.

Finally, thanks to Waldemarski for creating the logotype.
