Concepts underpinning participatory science communication have much to offer science communication training and capacity building. This paper investigates a capacity building program with 15 science communicators from nine African countries involved in a six-week program in Australia. Data was collected via surveys, observations, informal interactions and ongoing relationships tracking program outcomes. Key features with a participatory nature included: holistic programs giving participants diverse skills and entry points; ensuring participant's freedom, agency, autonomy and self-efficacy; real-world networking as a self-directed participatory process; participant-led design processes to build skills for creating programs; and, embedding training in real-world contexts with deliberately selected publics.

In this practice insight, an art-based, participatory intervention (#finaltrashtination) is presented as higher education assignment in environmental and climate change communication. The project #finaltrashtination made dominant environmentally destructive ways of wasting visible and stimulated students to take responsibility, advocacy and authorship for transformation. Beyond the one-day eco-culture jam, the project engaged the wider public through conversations about a specific environmental problem. Thus, the project shows how conversational problematization and sensemaking around scientific facts can be initiated by using eco-culture jams promoting very unsettling moments of reflection.

Despite the societal relevance of energy research, there is a distinct lack of citizen science initiatives in the field. This paper reports the experience of a participatory and innovative strategy to develop a citizen science initiative for solar energy research. A number of stakeholders participated in the definition and implementation of the initiative, and tools such as surveys and a hackathon were employed. The process described aims to provide a blueprint for transforming the relationship between citizens and research into societal challenges. Here we describe the collaborative process and analyse the main opportunities, limitations and future perspectives.

Young children are actors usually excluded from political decisions and also from many science communication projects. Participatory science communication models can help to connect their everyday life with both local policies and science-related content. Using visual methodologies for engagement, we aimed at understanding what preschool children prefer in the city landscape. Results show how young children envision a “better city” and how that construction might defy current scientific knowledge. It further illustrates how science communication can be used to co-produce new knowledge, contributing to the debate about people's needs and perceptions related to science-based options.

The ‘Born or Built? — Our Robotic Future’ (‘BOB?’) exhibition examines relationships between humans, robots and artificial intelligence. It encourages visitors to explore ethical and social issues surrounding these new technologies and invites visitors to post their own questions. We examine visitor responses to the exhibit “A of the Day”, which encourages visitors to engage by writing down their own question prompted by their experience in ‘BOB?’. As responses were submitted, it became apparent that the questions posed by visitors were potentially a valuable contribution to future science communication policy about robotics, and to those designing and implementing these technologies. We performed a content analysis that distilled themes in visitors' open-ended questioning that conveyed visitor knowledge and insight into what science communication about robotic technologies needs to address. Taken this way, visitors' questions form a moment of dialogue between the public and science communicators, engineers and researchers in which visitors contribute their knowledge and ideas about robotics. Such moments of dialogue are potentially valuable if the public is to be included in the development of robotics technology to build trust in robotics technology.

Despite being a critical environmental problem, soil pollution is not usually considered as a relevant issue by the general public. This disinterest derives from traditional procedures to assess soil pollution that are quite complex and costly, not considering any form of citizen involvement. Seeking to challenge this situation, the project “Nuestros Suelos” (Our Soil) aimed at designing and testing a low-cost participative soil pollution assessment toolkit. The final prototype included several participative modules, going from an assessment of the history of local soils to measuring heavy metals such as Arsenic and Copper. Tested with low-income communities in northern Chile, the toolkit was able not only to produce multiple kinds of data but also a public that started to understand and care about the issue.

This paper is the culmination of several meaning-making activities between an external researcher, PES practitioners, and social scientist researchers who considered the unique contributions that can be made through RPPs on PES (that is, research-practice partnerships on public engagement with science). Based on the experiences from three RPP projects, the group noted that the PES context may be particularly suited to RPPs, and identified the importance of working as thinking-partners who support reciprocal decision-making. Recommendations are made in support of using these approaches to advance practical knowledge-building and reduce shared frustrations about the disconnect between research and practice in PES.

Public engagement with science activities need to be extended beyond traditional learning venues (e.g., museums, schools) to increase public access. Scientists are motivated to carry out this work; however, it is difficult to scale up training to support the implementation of engagement activities in non-traditional venues. Such training would need to be applicable to different engagement contexts, while avoiding a “one size fits all” approach. We describe the guiding principles, challenges, and design choices of a training program in the United States to support scientists in designing and implementing audience-specific engagement activities in a range of non-traditional venues.

As several recent National Academies of Sciences reports have highlighted, greater science communication research is needed on 1) communicating chemistry, and 2) building research-practice partnerships to advance communication across science issues. Here we report our insights in both areas, gathered from a multi-year collaboration to advance our understanding of how to communicate about chemistry with the public. Researchers and practitioners from science museums across the U.S. partnered with academic social scientists in science communication to develop and conduct multi-strand data collections on chemistry communication and informal education. Our focus was on increasing interest in, the perceived relevance of, and self-efficacy concerning chemistry through hands-on activities and connecting chemistry to broader themes concerning everyday life and societal impacts. We outline challenges and benefits of the project that future collaborations can gain from and illustrate how our strands of work complemented each other to create a more complete picture of public perceptions of chemistry.

Podcasts are gaining traction in academic practice and debates. This article reflects on the experience of “The Sources of the Nile”, a podcast on media, science, and water diplomacy. By presenting the podcast structure and production process, we sketch a “podcast pathway” that might serve as a guide for others. We share the results of a survey conducted among our listeners and we review the episodes discussing what we learned on distributions of voice, knowledge and water in the Nile basin. We conclude by reflecting on the connection between the technical production of the podcast and the type of knowledge that it generates, and by pointing at the importance of placing the podcast within a broader community of interests and practice.
