Organized by Fab Lab Zagreb during the Croatia #STEAM Week, this lecture + workshop aims to open the mind and inspire Croatia teachers from formal K12 education through a hands on distributed and active learning activity. The main objective was to understand the process, tools and framework for prototyping #steam and maker-centered learning projects. We will accompany and train the trainers so they can learn and develop key digital skills and competencies and facilitate the transition to educational communities to become digital social innovators who respond to the challenges posed by Sustainable Development Goals (ODS 11, Cities and sustainable communities).
