I'm a software developer and cognitive scientist (currently working at Space Applications Services, Belgium).
Previously I used StarLogo to teach programming to a young student (age: 13) and recently I've been using Scratch to introduce computational thinking concepts to studens (age grou: 11-12). My experience for the last 3 months have been very positive and I want to teach more children.
