In 2020, National Science Week events shifted online in response to Australian COVID-19 restrictions. Our research captures this rapid pivot from in-person to online science events, exploring experiences through audience and presenter questionnaires, and follow-up interviews. We examine characteristics of audiences for online science events, benefits and barriers of these events, and opportunities for online engagement. Key benefits were ease of attendance, new experiences enabled online, and greater control and flexibility. Lack of social interaction, technology issues, and audience reliability were identified as barriers. Our research suggests online events operate in a different sphere to in-person events and informs the delivery of engaging online experiences.

This paper synthesizes the efforts of an interdisciplinary, University-convened communication task force in the U.S. that used science communication theory to develop an effective strategy during the early stages of the COVID-19 pandemic. We outline recommendations for researchers and practitioners who are, or are interested in, implementing theory-based communication practices while describing how we dealt with the unforeseen realities we faced. Overall, we recommend that effective public health and science communication should be based on theory and formative evaluation while relying on established infrastructure, real-time data, a deep understanding of intended target audiences, and intentional coordination with community partners.

In this editorial, we reflect on our new roles as Editor-in-Chief and Deputy Editor of JCOM. We acknowledge the work of previous editors of JCOM, the Editorial Office and the wider JCOM community who have contributed to the success of the journal. We introduce the new Editorial Board and future directions for the journal, and we encourage suggestions from authors, reviewers and readers for taking the journal forward.

This essay approaches the question: ‘What does participatory science communication for transformation mean in Colombia?’ The answer comes from an examination of the public policy instruments that have promoted participatory scientific communication through the concept of social appropriation of science, technology, and innovation (STI). In the gaze of these public policy instruments, it is evident how the social appropriation of STI has been intended as a means of transformation.

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.

Participatory science communication featured in several sessions and individual papers at the 2021 online conference of the Public Communication of Science and Technology (PCST) Network. This coverage recognises the drive away from linear communication to more participatory forms of science communication. In this special edition we present practice insights, papers and essays that explore participatory science communication. These contributions explore definitions, processes and describe case-studies of participatory science communication which involve a variety of publics, from young school students to Indigenous groups to farmers. In this introductory editorial we reflect on the papers, describe the growth of a participatory approach as part of the continuing evolution of science communication; explore a definition for participatory science communication; and consider some of the key concepts and issues that emerged.

Traditionally, the Royal Institution's Christmas Lectures have always adopted a deficit model for communication, with one or two invited scientists giving lectures to an audience present at the Royal Institution (Ri) and, since 1936, an audience watching the lectures on television at home. As trends in public engagement have tended towards more dialogue or participatory models, the Ri has made efforts to create a programme of events around the lectures: extending the experience outside of the lecture theatre and giving audiences more opportunities to experience live events and participate in discourse. In this paper, we explore data collected as part of an 18 month evaluation of the Christmas Lectures and their associated events. We focus on data collected at events designed to create live and interactive experiences beyond the lectures and evaluate these participatory approaches. The paper shares this learning to enhance the extension of traditional science communication towards science participation.

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.

While short-term participatory science communication activities have been well researched, long-term programs have received scant attention. Analysing survey data and participant discussions, I investigated interactions between Australian farmers and scientists engaged in the Climate Champion Program (2009–2016). I compared their interactions to three theorised science communication models: deficit, dialogue and participatory. I found their interactions illustrated a mix of the characteristics of all three models. While farmers and scientists appeared to be motivated to interact by deficit and dialogue objectives, respectful and trusting relationships emerged from long-term participation, which was key to making deficit- and dialogue-style communication more effective.

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.
