The ability to storyboard or communicate with non-specialist audiences are key skills, highly regarded by graduate employers. Recent research (Lewis, unpublished) has shown that there are limited opportunities within UK STEM undergraduate programmes for students to be provided, either with science communication training, or to participate in public engagement activities yet there is considerable demand from students for such provision. In addition, the “Working towards your Future” report (CBI & NUS, 2011) recommended that Universities provide opportunities, outside of the curriculum, for students to develop employability skills and gain relevant work experience.In response to this demand, ES (student) and DL (staff) founded Pop-Up Science, a student-led, public engagement volunteer scheme. The objective, for students to work in teams to create and deliver public engagement activites; their audience predominantly “hard to reach” sections of the community or those that do not normally engage with science. This scheme was advertised to to all undergraduate students within the Faculty of Biological Sciences and 23 students, who collectively represented all disciplines and year groups across the Faculty, were recruited. Students attended a public engagement training workshop, they then worked collaboratively in self-selected groups to create sessions on, for example, “Healthy hearts”, “Bendy bones” and “Sporting performance”. The initial public engagement event was led by the scheme student lead. Students on subsquent sessions were mentored in the creation and delivery of their sessions by the student lead or by students who had participated in earlier events. Individual sessions were delivered at venues across Yorkshire including the Eureka (National Children’s Museum), the Yorkshire Big Bang Festival, Springtime Live (family funday at the Yorkshire Showground) and the Yorkshire Festival (prelude to the Tour de France Grand Départ). To gain the most out their participation, students are required to reflect on their experiences and the skills gained, both before and after delivery of an event, and to blog these reflections.To date, the scheme has recieved excellent feedback from the public, event organisers and the student volunteers; the latter recognising the key skills gained. “became more confident in myself….better at explaining in a way that was both fun and interesting””being able to think on my feet and adapt to different audiences….a challenge speaking in very lay terms, communication skills definitely benefited…..good team-working was essential”This scheme enables students to develop key science communication skills and gain valuable public engagement experience. It provides significant benefits for the Faculty in enhancing the student learning experience, developing graduate attributes and in the promotion of its activities.
