I have done loads of things and it is difficult to say which one I think it was the most interesting. But if I would have to choose, I would say that being part of the core organising committee for the Teacher In-Service Program Week 2016 was the most interesting one.
The event is a sort of outreach event, and we train teachers to teach hand-on activities in schools. When we started the event, we were aiming for 200 teachers to participate. When we had the event, we had a total of 650 teachers. The event took place in 15 different countries during a week in October, and we want to make it even bigger this year.
