”Roteco” - a Swiss teacher community for educational robotics.

Computer Science has been introduced as a new subject in the com- pulsory school curriculum in Switzerland. Research on educational robotics has highlighted potentials of using robots as a hands-on tool to foster computational thinking skills. However, to date these kind of activities are not carried out systematically in schools. To support teachers, a teacher community for educational robotics and computer science education "Roteco" has been established. Teachers can register for free to a digital platform to find classroom-ready activities, news, articles, and information about training and work- shops in their region. Roteco further organizes webinars and events to build the community. Within two years, more than 1,400 teachers have joined the community. In this abstract, we present Roteco, our experiences in establishing the community, platform analytics data as well as a short summary of results from two surveys conducted in 2020 with 87 and in 2021 with 48 teachers. Detailed results can be found in the corresponding journal article [11].
