Effective classification of large datasets is a ubiquitous challenge across multiple knowledge domains. One solution gaining in popularity is to perform distributed data analysis via online citizen science platforms, such as the Zooniverse. The resulting growth in project numbers is increasing the need to improve understanding of the volunteer experience; as the sustainability of citizen science is dependent on our ability to design for engagement and usability. Here, we examine volunteer interaction with 63 projects, representing the most comprehensive collection of online citizen science project data gathered to date. Together, this analysis demonstrates how subtle project design changes can influence many facets of volunteer interaction, including when and how much volunteers interact, and, importantly, who participates. Our findings highlight the tension between designing for social good and broad community engagement, versus optimizing for scientific and analytical efficiency.

Identifying private gardens in the U.K. as key sites of environmental engagement, we look at how a longer-term online citizen science programme facilitated the development of new and personal attachments of nature. These were visible through new or renewed interest in wildlife-friendly gardening practices and attitudinal shifts in a large proportion of its participants. Qualitative and quantitative data, collected via interviews, focus groups, surveys and logging of user behaviours, revealed that cultivating a fascination with species identification was key to both ‘helping nature’ and wider learning, with the programme creating a space where scientific and non-scientific knowledge could co-exist and reinforce one another.

The 15th international conference of the Public Communication of Science and Technology network took place from April 4–6, 2018. Given its location in Dunedin, New Zealand/Ōtepoti, Aotearoa, it was a natural venue for two sessions on communicating science across cultures.

This paper presents the first study ever conducted on the profile of visitors to the Museum of Human Evolution of Burgos (Spain), which exhibits the finds of the Atapuerca archaeo-paleontological sites. The research was guided by the principles of public communication of science and the methodology of the studies on museum visitors. The analysis reveals a positive perception; the Museum is associated with the sites and they are valued as cultural heritage. Complaints are very limited but useful to produce a set of recommendations to further improve the exhibition. In addition, the findings are placed in the context of similar research carried out at other museums in Spain.

We explored the potential of science to facilitate social inclusion with teenagers who had interrupted their studies before the terms set for compulsory education. The project was carried out from 2014 to 2018 within SISSA (International School for Advanced Studies), a scientific and higher education institution in physics, mathematics and neurosciences, and was focused on the production of video games using Scratch. The outcomes are encouraging: through active engagement, the participants have succeeded in completing complex projects, taking responsibilities and interacting with people outside their usual entourage, within a background in which they have been valued and respected.

It can be argued that ethical considerations in science communication are a significantly overlooked area although these considerations are implicit in many ongoing academic debates within the field, and within the practical implications of work which is being both constructed and shared within the discipline. Priest, Goodwin and Dahlstrom's [2018] edited collection, ‘Ethics and Practice in Science Communication’, is therefore a significant step forwards in allowing for contemporary reflection on the ethical considerations currently influencing the field. In shining a light on some of the ethical questions currently concerning the field of science communication, this enjoyable and detailed selection of chapters draws together a number of key examples and authors, to begin to consider such ethical quandaries, as well as identifying spaces, which are primed for further ethical exploration in the future.

Environmental Pedagogies and Practice is divided into four sections: changing environmental pedagogies, teaching practices, examples of transformative approaches and a toolkit of lesson plans. While the book focuses on environmental communication, the chapters offer insights that are also relevant in a range of science communication contexts.

According to the Gateway Belief Model, scientists and science educators should stress the scientific consensus when engaging with the lay population across a wide variety of mediums, including debates. The purpose of this study, then, was to determine if engaging in such debates does more harm than good in terms of persuading individuals towards accepting the scientific consensus of controversial issues. Participants (N = 208) read a manipulated debate segment altered by the issue discussed as well as the position/title of the skeptic debater. Results indicate that it is possible to influence individuals exposed to these debate segments, but the effects are issue-contingent. Limitations and future research related to science education are discussed.

In November 2016, within an Environmental studies course at the University of Venice, students carried out an experiment aimed at collecting scenarios of the Venetian coast's future starting from lessons learnt during the episode of storm surge 50 years ago (Aqua Granda ‘flood’). The students built scenarios able to anticipate the effect of sea level rise on coastal areas in Venice, based not only on scientific input but also on a methodology called “Futurescape city Tours” (FCT) involving inhabitants of the barrier islands of Lido and Pellestrina. This paper will explore three main questions: (i) Can participatory and experiential methodologies, such as FCT help students behave in an anticipatory and inclusive way in their future professional activities? (ii) Can we talk about post-normal science teaching? — i.e. one that acknowledges and works with science and other knowledges to address societal issues? (iii) Can such an approach challenge students thinking in relation to knowledge hierarchies?

This paper is a reflective account of a public participation project the authors conducted in Japan in 2012–2015, as part of the central government's initiative for evidence-based policy-making. The reflection focusses on three key aspects of the project: setting a precedent of involving public participation in policy-making; embedding an official mechanism for public participation in policy-making process; and raising policy practitioners' awareness of public participation. We also discuss why we think engaging with policy practitioners, while problematic in various ways, is and will continue to be important in promoting institutionalised practice of public participation.
