This article contributes to reflective practice amongst scientists who engage with citizens in the digital public sphere, by exploring the scientists' experiences and underlying perspectives on their role repertoires in online science-society interactions. Semi-structured interviews were held with 26 European scientists to investigate their focus and contribution in boundary interactions, perspective on appropriate model of science communication, and activities, outputs and addressees in the digital public sphere — together comprising a role repertoire. The intended role of scientists often did not match with their deployed repertoire in online interactions with citizens. Participants were left with the feeling that the digital public sphere provides hollow interactions, devaluates scientific expertise or even represents a hostile environment. In order to capitalise on the promise of the digital public sphere for constructive interactions with a diverse public, a reflective practice is needed that aligns scientists' intended contribution to science-society interactions with the scientists' perspective and deployed online repertoires.

Communities are rarely seen as the ideal level at which to focus science communication efforts, compared to the individual, psychological or mass, societal levels. Yet evidence from allied fields suggests building interpersonal relationships with specific communities over time is key to meaningful engagement, so orienting science communication towards communities is warranted. In this paper, we argue this case. We review previous studies, identifying three existing models of community-oriented science communication, which we label ‘neighbourly’, ‘problem-solving’ and ‘brokering’. We illustrate the effectiveness of the ‘problem-solving’ approach and the desirable ideal of ‘brokering’ using recent examples of community-oriented science communication from Australia.

Science communication continues to grow, develop and change, as a practice and field of research. The boundaries between science and the rest of society are blurring. Digitalization transforms the public sphere. This JCOM special issue aims to rethink science communication in light of the changing science communication landscape. How to characterize the emerging science communication ecosystem in relation to the introduction of new media and actors involved? What new practices are emerging? How is the quality of science communication maintained or improved? We present a selection of papers that provide different perspectives on these questions and challenges.

Although the need to improve quality of science communication is often mentioned in public discussions, the science communication literature offers few conceptualizations of quality. We used a concept mapping approach, involving representatives of various science communication stakeholder groups working collaboratively, to propose a framework of quality. The framework organizes individual elements of quality into twelve indicators arranged into three dimensions: trustworthiness and scientific rigour, presentation and style, and connection with society. The framework supports science communicators in reflecting on their current practices and designing new activities, potentially improving communication effectiveness.

Citizen science is a transdisciplinary approach that responds to the current science policy agenda: in terms of supporting open science, and by using a range of science communication instruments. In particular, it opens up scientific research processes by involving citizens at different phases; this also creates a range of opportunities for science communication to happen This article explores methodological and practical characteristics of citizen science as a form of science communication by examining three case studies that took different approaches to citizens' participation in science. Through these, it becomes clear that communication in citizen science is ‘÷always’ science communication and an essential part of “doing science”.

In this essay the authors reflect on some recent trends in science communication research, celebrating it as an inherently interdisciplinary endeavour. Some current tendencies in science communication are more limiting, however: they present theoretical and strategic prescriptions that do not adquately reflect the variety and cultural diversity of science communication internationally. Rethinking science communication in the context of such diverse practices and cultural reorientations, the authors revise some of their own views and revisit notions of communication as conversation to propose an inclusive definition of science communication as the social conversation around science.

In this essay, we explore what happens when science meets comic art and how such meeting offers an opportunity to rethink science communication. We base our discussion on our own experience, as research scholars, of engaging in a collaboration with a comic artist. Three key reflections are developed: how comic art may help to (1) conceptualize ideas in an early research phase, (2) clarify the main argument by making the (un)written word visible; and (3) communicate science with an open end. These aspects contribute to an increased understanding of science communication in both research and society.

We lack a good framework to characterize media-related adaptations of researchers. This paper explores Estonian scientists visible in the media to propose five dimensions to characterize the degree of mediatization of a researcher, and describes two basic types of visible scientists. Representatives of one type (‘adapters to media logic’) are able to explain the project simply and engagingly in the media, while those of the second type (‘adopters of media logic’) proactively create media interactions and manage them to achieve strategic aims. The results show how individual actors translate communication objectives into media practices, explaining variabilities in scientists' media presence.

In this commentary we are concerned with what mainstream science communication has neglected through cultural narrowness and ambient racism: other practitioners, missing audiences, unvalued knowledge, unrecognised practices. We explore examples from First Nations Peoples in the lands now known as Australia, from Griots in West Africa and from People's Science Movements in India to help us reimagine science communication. To develop meaningfully inclusive approaches to science communication, we argue there is an urgent need for the ‘mainstream’ to recognise, value and learn from science communication practices that are all too often seen as at ‘the margins’ of this field.

Many people are under-served by existing informal science learning (ISL) provisions and under-represented in STEAM (Science, Technology, Engineering, Arts, Mathematics/Medicine) study choices and careers. This paper reflects upon SMASHfestUK which was established, as both a STEAM festival and research platform, to explore methods and approaches for lowering the barriers to engagement with ISL in marginalised communities. To do this SMASHfestUK located its events in the heart of communities and worked with these communities to create those events. This paper tells their story through the voices of participating communities.
