<< Objectives >>Our main objective is to improve STEM scientists’ ability to communicate their science to diversified audiences. Communicating science beyond expert audiences has been recognized as a key societal priority. Yet, resources and training designed to enable scientists to do so are lacking. This project will contribute to solving this problem by creating digital resources for professional development to assist STEM scientists (in particular women) to better communicate their science to society.<< Implementation >>We will conduct an ethnomethodological study to obtain data from EU STEM scientists (in particular women) on digital science communication practices and identify their good practices. Informed by this study, we will create instructional materials and develop a fully digital (online) training course, a MOOC and a virtual resource hub to help EU STEM scientists communicate more effectively to public audiences through different modes and digital media and enhance their cross-cultural sensitivity.<< Results >>Using empirical data, we will create an inventory of good practices for communicating science online to multidisciplinary audiences. We will create a sustainable infrastructure (a digital communication training hub) to support the resources for the two course types (testimonials of female scientists on digital communication practices, videotutorials, multiliteracy skills development tasks, guidelines for trainers). We target STEM scientists but the hub will be inclusive of non-STEM scientists.
