We are pleased to welcome into the world the new journal “Citizen Science: Theory and Practice” – one hope for this Citizen Science Today aggregator site is to bring forward grey literature from e.g. blog posts and promote it as an important part of the emerging conversation on citizen science that CSTP will only enhance. — LFF — The…

Abstract: Online Citizen Science platforms are good examples of socio-technical systems where technology-enabled interactions occur between scientists and the general public (volunteers). Citizen Science platforms usually host multiple Citizen Science projects, and allow volunteers to choose the ones to participate in. Recent work in the area has demonstrated a positive feedback loop between participation and…

We could have filled this month’s edition of Citizen Science Today with articles from this special edition of JCOM. Instead, follow the link below to read widely and deeply about the field. – CJL – JCOM is an open access journal on science communication. Since the world of communication and the scientific community are now…

Abstract: 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…

Abstract: The human auditory system is adept at detecting sound sources of interest from a complex mixture of several other simultaneous sounds. The ability to selectively attend to the speech of one speaker whilst ignoring other speakers and background noise is of vital biological significance—the capacity to make sense of complex ‘auditory scenes’ is significantly…

This isn’t a new book, but it’s an interesting take on an old story not much discussed in the citizen science community. Perhaps historians of twentieth century citizen science are needed alongside their more common nineteenth century colleagues. – CJL – Technological advances come in such small increments that we rarely think about their accumulated…

Abstract: 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…

Abstract: Citizen science has the potential to expand the scope and scale of research in ecology and conservation, but many professional researchers remain skeptical of data produced by nonexperts. We devised an approach for producing accurate, reliable data from untrained, nonexpert volunteers. On the citizen science website www.snapshotserengeti.org, more than 28,000 volunteers classified 1.51 million images…

Abstract: The first Ocean Sampling Day (OSD) took place on June 21, 2014. In a coordinated effort, an internationally distributed group of scientists collected samples from marine surface waters in order to study microbial diversity on a single day with global granularity. Concurrently, citizen scientists enriched the OSD initiative through the MyOSD project, providing additional…

Abstract: Crowdsourcing can efficiently complete tasks that are difficult to automate, but the quality of crowdsourced data is tricky to evaluate. Algorithms to grade volunteer work often assume that all tasks are similarly difficult, an assumption that is frequently false. We use a cropland identification game with over 2,600 participants and 165,000 unique tasks to…
