The authors present a quantitative content analysis to assess the use of mathematical information in the news of five generalist Portuguese newspapers during a three-month period. Misuses of mathematics were also studied in this context. Results show that only a small percentage of the news articles have mathematical information when compared to previous studies in the field. Furthermore, over 30% of the news articles containing mathematical information have some type of mathematical error. Different categories of errors are defined and reasons why these might occur are discussed.

The letter compares and contrasts thinking about making science accessible and relevant to children in science centres and museums with thinking about communication in social history museums.

This article provides a first statistical analysis of the typologies and characteristics of popular science web videos on YouTube. An analysis of 190 videos from 95 online video channels was conducted. Several factors such as narrative strategies, video editing techniques, and design tendencies with regard to cinematography, the number of shots, the kind of montage used, and even the use of sound design and special FX point to a notable professionalism among science communicators independent of institutional or personal commitments. This analysis represents an important step in understanding the essence of current popular science web videos and provides an evidence-based description of their distinctive features.

This study aims to investigate whether different types of museum visits have specific ways to influence the visitors' experience and learning. Three types of museum visits as offered by the Museo della Scienza e della Tecnologia "Leonardo da Vinci" in Milan, Italy were taken into consideration: free tour, guided tour, and lab. The study involved visitors over 25 years of age. The way visits took place, the visitors' learning and experiences were investigated based on evidence collected using methods such as Personal Meaning Mapping and observation. Our study has revealed that the outcomes of the visits vary in terms of visitor experience and depth of knowledge on the main subject. No significant differences were found as concerns the level of attention (visitors proved to be attentive while at the museum regardless of the type of visit).

The participation of non-professionally trained people in so-called citizen science (CS) projects is a much discussed topic at the moment. Frequently, however, the contribution of citizens is limited to only a few narrow tasks. Focusing on an initiative dedicated to the study of the human microbiome, this paper describes such a case where citizen participation is limited to the provision of funding, samples, and personal data. Researchers opted for a crowdsourced approaches because other forms of funding and recruitment did not seem feasible. We argue that despite the narrow understanding of participation in the context of some CS projects, they can address some of the democratic concerns related to scientific knowledge creation. For example, CS and crowdsourcing can help to foster dialogue between researchers and publics, and increase the influence of citizens on research agenda setting.

Despite the rapid expansion of citizen-based monitoring, data from these programs remain underutilized by natural resource managers, perhaps due to quality and comparability issues. We present the Bosque Ecosystem Monitoring Program as a case study of an initiative successfully meeting long-term monitoring needs of federal, state, tribal, and local natural resource managers, and informing public policy. To maximize potential for partnerships with managers, we recommend the creation of a five-year plan including scientific goals and financial solvency strategies prior to establishing a citizen science program, and offering multiple platforms for data-sharing and dialogue.

We investigate the development of scientific content knowledge of volunteers participating in online citizen science projects in the Zooniverse (http://www.zooniverse.org). We use econometric methods to test how measures of project participation relate to success in a science quiz, controlling for factors known to correlate with scientific knowledge. Citizen scientists believe they are learning about both the content and processes of science through their participation. We don't directly test the latter, but we find evidence to support the former — that more actively engaged participants perform better in a project-specific science knowledge quiz, even after controlling for their general science knowledge. We interpret this as evidence of learning of science content inspired by participation in online citizen science.

There is growing recognition that effective science communication should not merely focus on addressing scientific literacy but must also open dialogue between scientists and the public, build trust, and increase public interest in environmental research. Citizen science BioBlitzes offer a useful approach for science communicators to address many of these key aims. We explore the BioBlitz concept, learnings and outcomes based on a case study of a BioBlitz held in Sydney, Australia. We found that participants valued learning about biodiversity on the day and importantly, all participants (scientists and citizen scientists) rated interacting and learning from the experience as one of the main benefits.

Volunteer water quality monitors represent the intersection between citizen science and environmental stewardship. Understanding what motivates participation will enable project managers to improve recruitment and retention. This survey of 271 volunteers from eight water quality monitoring organizations in the U.S. found the strongest motivators to participate are helping the environment or community and contributing to scientific knowledge. No variation by gender was found, but younger volunteers have different motivations and preferences than older volunteers. Volunteers value the communication of tangible results more than recognition or reward.

Online citizen science projects have demonstrated their usefulness for research, however little is known about the potential benefits for volunteers. We conducted 39 interviews (28 volunteers, 11 researchers) to gain a greater understanding of volunteers' motivations, learning and creativity (MLC). In our MLC model we explain that participating and progressing in a project community provides volunteers with many indirect opportunities for learning and creativity. The more aspects that volunteers are involved in, the more likely they are to sustain their participation in the project. These results have implications for the design and management of online citizen science projects. It is important to provide users with tools to communicate in order to supporting social learning, community building and sharing.
