In the fifth episode of the "Arqus Knowledge Pills", we talk to Valentina Dagienė, a professor of informatics at Vilnius University. She is one of the founders of the “Bebras Project”, a worldwide network that strives to kindle enthusiasm for Computer Science in children, teenagers and teachers. Valentina tells us how the challenges are organized in the partner countries around the world, why it is so important to foster computational thinking and also why a beaver is the mascot of this project.
