The great increase in visitor studies on science museums and centres (SMC) has been marked also by a shift in approach to these studies, paying more attention to the social context of the visits and the nature of the experience. Evaluations have influenced directly SMC exhibition practices but more attention needs to be paid in research about the personal experiences of visits, how these are interpreted and how they contribute to scientific literacy.

Metaphors and visualizations are important for science communication, though they may have limitations. This paper describes the development and evaluation of a novel interactive visualization, the "Dynamic Evolutionary Map"' (DEM), which communicates biological evolution using a non-standard metaphor. The DEM uses a map metaphor and interactivity to address conceptual limitations of traditional tree-based evolutionary representations. In a pilot evaluation biology novices used the DEM to answer questions about evolution. The results suggest that this visualization communicates some conceptual affordances differently than trees. Therefore, the described approach of building alternative visual metaphors for challenging concepts appears useful for science communication.

An evaluation toolkit developed as part of the EU-funded PLACES project was applied in 26 case studies across Europe. Results show, among other things, the contribution of science communication initiatives to public curiosity, professional networking and perception of cities where these initiatives are stronger.

Evaluations of science communication activities before, during and after their implementation can provide findings that are useful in planning further activities. As some selected examples show, designing such evaluation is complex: they may involve assessment at various points, a mix of quantitative and qualitative methods, and show that impacts differ when seen from different perspectives.

As science museums and centres (SMC) broaden their practices to include the development of scientific citizenship, evaluation needs also to take account of this dimension of their practices. It requires complex methods to understand better the impacts of public participation in activities mediated by SMC, including their impacts on the governance of the SMC themselves.

This paper explores media coverage of climate science through a selection of Spanish newspapers (El País, El Mundo, ABC, Expansión and Levante). We selected a stratified random sample of 363 items to be studied for eleven years (2000-2010). Content analysis allowed us to find out media attention paid to climate science, prevalence of informative tables, evaluation and characterization of news, as well as the presence of questioning or rejection of climate change. According to main results, press coverage of climate science in Spain was mainly focused on the consequences rather than on the causes or natural sources, and media attention paid to it was limited. Overlapping with social and macroeconomic problems in the country also contributed to communication of climate science as a controversial and uncertain science through informative framings.

The study investigated the extent to which transmission and cognition, the first two stages in the research use process, are accomplished for winemakers. “Transmission-cognition” was operationalized as the frequency of engagement with information sources considered to be carriers of scientific research. The study also investigated the prominence of four types of research use among winemakers (conceptual, symbolic, instrumental and persuasive) together with their inter-relationship. Conceptual use of scientific information was reported by 90% of winemakers and is a precursor to the other types of research use. Findings are discussed with reference to knowledge creep and the dissemination of scientific research through central winemakers acting as nodes in social networks.

In the last two years SISSA Medialab designed, tested and evaluated two projects aiming at empowering children (in one case) and teenagers (in the other) to act as science journalists in order to promote a personal, critical attitude towards science and technology. The two groups produced a paper magazine and a blog, respectively, in a participatory process, in which adults acted as facilitators and experts on demand, but the youths were the leaders and owners of the products. Special care was taken to ensure inclusiveness, by involving in the project children and teenagers from any social class including those not especially interested in science and technology before participating in the project.

In the editorial of this issue of JCOM, we underline how children are on one hand one of the main target group for science communication, and on the other hand a largely excluded group in the shift from a linear diffusion model to a dialogic model of science communication. In this series of comments, stimulated by the EU - FP7-Science in society project `SiS-Catalyst - 2013 children as change agents for science in society' (a four year programme aimed at crossing the science in society and the social inclusion agendas), we would like to explore methods and approaches that can ensure that, in science communication contexts, children can be listened to, that they are given the chance to express their view, and that they can be empowered in building their own relationship with science, and thus a sense of ownership for scientific knowledge.

Children’s issues have become a greater priority on political agendas since the UN General Assembly adopted the Convention on the Rights of the Child (UNCRC). Each government has agreed to ensure that all those working with and for children understand their duties in relation to upholding children’s rights including the obligation to involve children in decisions that affect them (Article 12). Respecting children’s views is not just a model of good pedagogical practice, but a legally binding obligation. However, there is a limited awareness of Article 12, and how to actualise it. While many people speak about the ‘voice of the child’ or ‘student voice’, these concepts do not capture the full extent of the provision. Lundy (2007) developed a model, which helps duty bearers involve children meaningfully in decision-making. According to this model four separate factors require consideration: Space, Voice, Audience, and Influence. In this paper, we provide an overview of these four factors and a summary of the main implications of the model.
