Communities of practice in science communication can make important contributions to public engagement with science but are under-researched. In this article, we look at the perspectives of a community of practice in astronomy communication regarding (relations with) their public(s). Most participants in this study consider that public(s) have several deficits and vulnerabilities. Moreover, practitioners have little to no contact with (and therefore make no use of) academic research on science communication. We argue that collaboration between science communication researchers and practitioners could benefit the science-public relationship and that communities of practice may be critical to that purpose.

Knowing how specific publics understand and experience science is crucial for both researchers and practitioners. As learning and meaning-making develop over time, depending on a combination of factors, creative possibilities to analyze those processes are needed to improve evaluation of science communication practices. We examine how first grade children's drawings expressed their perceptions of the Sun and explore their views of a major astronomical body within their social, cultural and personal worlds. We then examine how the observation of the Sun through a telescope led to changes in graphical representations, and how learning and meaning evolved after several months.

Climate change is a multi-faceted issue. It relies on deep scientific bases, but merges with politics, economics, ethics and culture in a complex and strongly nonlinear social debate. This interview focuses on the relationships between public communication on climate change (with emphasis on the so-called ‘new media’) and the decision making processes. It argues that more productive and sustainable forms of communication on climate change are needed due to problems related with validation of information in the Web.
