CCTC 2021
Catrobat Computational Thinking Conference

Virtual Conference – 24th September 2021 –

Smartphones have become the predominant way teenagers and children interact online, and mobile apps offer a unique way to engage this audience. Catorbats apps are used in this area, particularly for playing and creating apps and games, thus teaching basic programming skills. 

In 2020, Catrobat celebrated it's 10th anniversary!

This year we will catch up with this event with an online academic workshop/demo day on September 24 2021, and a celebration with the development team and contributors on September 25 2021 on-site at Graz University of Technology. 

Catrobat Conference is seeking submissions for Demos and Workshops that focus on visual block-based programming, Computational Thinking, and design and making in education. We welcome submissions from multiple sectors and disciplines, including but not limited to academia, industry, and education, aiming for transdisciplinary understanding. Key areas of interest are:
