This study applies social network analysis to explore the role that one science festival has played in building the state's STEM learning ecosystem. It examines the breadth and extent of collaboration among STEM educators and their partners, reviewing past and present partnerships across 449 events during the 2015 festival. Three case studies provide in-depth illustrations of partnerships. These findings represent an important step towards (a) mapping a STEM learning ecosystem, and (b) trying to understand how a festival affects the ecosystem itself. Together, study results demonstrate how the festival has served to stimulate and foster STEM partnerships.

Celebrating 15 years of success and growth, the STS Conference Graz on May 9 and 10, 2016, gathered nearly 200 delegates from all over the world who had the opportunity to discuss and share research and experiences on 6 main themes: Policy and Technology; Gender and Queer STS; Mobility, Energy and Sustainability; Responsible Research and Innovation Studies; Nutrition, Health and Biomedicine; and Information and Communication Technologies, Surveillance and Society.

The twenty-first century has witnessed a shift in science communication ideals from one-way science popularization activities towards more reflexive, participatory approaches to public engagement with science. Yet our longue duéee histories of science communication's antecedents focus on the former and have neglected the latter. In this paper I identify parallels between modern science communication ideals and an iconic Enlightenment text, Condorcet's Sketch for a Historical Picture of the Progress of the Human Mind (1795). I show that Condorcet's carefully negotiated balance between scientific reason and radical principles of democracy has much in common with twenty-first century debates about science communication.

This issue forms Part II of JCOM's collection of articles and essays exploring the field of citizen science. Here I introduce the articles in Part II, outlining how they contribute to our understanding of the ways that volunteers participate in citizen science projects, what motivates this participation and what learning arises as a result of participation.

Community-based water monitoring (CBWM) provides essential baseline information on watershed health and engages the public in science, but those involved often encounter barriers to informing environmental management. We conducted qualitative interviews with watershed group coordinators and government counterparts from four CBWM organizations to explore instances where CBWM successfully influenced governmental decision-making. Our findings show that the level of rigor for quality standards, inclusion of volunteers, available resources, and desired goals are important considerations when designing community-based monitoring programs. Integrated program designs that include adequate quality standards and engage volunteers are more apt to maximize resources and realize both scientific and educational goals.

In recent years, citizen science has gained popularity not only in the scientific community but also with the general public. The potential it projects in fostering an open and participatory approach to science, decreasing the distance between science and society, and contributing to the wider goal of an inclusive society is being explored by scientists, science communicators, educators, policy makers and related stakeholders. The public's participation in citizen science projects is still often reduced to data gathering and data manipulation such as classification of data. However, the citizen science landscape is much broader and diverse, inter alia due to the participation opportunities offered by latest ICT. The emergence of new forms of collaboration and grassroots initiatives is currently being experienced. In an open consultation process that led to the "White Paper on Citizen Science for Europe", the support of a wide range of project types and innovative forms of participation in science was requested. In this paper we argue for mechanisms that encourage a variety of approaches, promote emerging and creative concepts and widen the perspectives for social innovation.

Citizen Science is part of a broader reconfiguration of the relationship between science and the public in the digital age: Knowledge production and the reception of scientific knowledge are becoming increasingly socially inclusive. We argue that the digital revolution brings the "problem of extension" — identified by Collins and Evans in the context of science and technology governance — now closer to the core of scientific practice. In order to grasp the implications of the inclusion of non-experts in science, the aim of this contribution is to define a role-set of non-certified knowledge production and reception, serving as a heuristic instrument for empirical clarifications.

Citizen science is one of the most dramatic developments in science communication in the last generation. But analyses of citizen science, of what it means for science and especially for science communication, have just begun to appear. Articles in this first of two special issues of JCOM address three intertwined concerns in this emerging field: The motivation of citizen science participants, the relationship of citizen science with education, and the implications of participation for creation of democratic engagement in science-linked issues. Ultimately these articles contribute to answering the core question: What does citizen science mean?
