A special method of teaching Physics: Outdoors radioactivity measurements

We recognised that students can be motivated by those issues they are personally affected by. Such topic can be nuclear radiation that we live in. The realization led to the school project of radioactivity measurement. We joined the international Safecast projekt. Safecast is an outdoors radioactivity measurement project that represents a long-term and effective way of informal teaching of Physics outside classroom environment.. We noticed a unique contradiction between the demand of developed nuclear technologies and the societal attitude declining these. After the disaster of Fukushima, people's nuclear sense of security has decreased in a global extent. This model is a successful initiative worldwide for the restoration of trust. Results of the measurement can be viewed by people all around the world on Google Maps and they are incredible impressive. The implemented project is a decent combination of formal and informal learning, based on the model of research-based teaching. After our 1-year observation, we were able to encourage 20% of inactive students to participate in Safecast project – using an informal teaching style. In groups of 20 and 25, the sense of nuclear safety of members increased 18% and 22%. (paper)
