After celebrating ten years of Communicating Science workshops this spring, the AAAS Center for Public Engagement with Science & Technology recently hit another milestone: its 200th workshop. These workshops have provided more than 6,400 scientists and engineers around the United States – and sometimes beyond (AAAS workshop facilitators have traveled as far as Kuwait and Chile) – the opportunity to learn core communication skills and to think strategically about their goals for engaging in two-way conversations about science with non-technical audiences.
