Citizen science against the plastic soup: background, motivation and expectations of volunteers studying plastic pollution on Dutch riverbanks

In the field of investigating and addressing plastic pollution, the public is increasingly involved in research as citizen scientists. Long-term monitoring for this topic is needed, and recruiting and retaining volunteers is challenging. Therefore, it is important to learn more about the demographic background, motivations and expectations of involved citizen scientists, and if these change during participation. Our research studied these aspects of the citizen scientists in the Dutch Clean Rivers project, who monitor plastic pollution on riverbanks. Participants (n = 122) completed pre- and post-survey after one year of the project. While there was no gender bias, the participants were mostly middle-aged and highly educated, and almost half had previous experience with scientific research. Their motivation to participate was mostly activistic, as they wanted to tackle the source of plastic pollution and contribute to solutions. More personal motivations, such as wanting to learn more and because it is fun to do scientific research, decreased significantly after one year of participation. Their expectations were in line with the main motivations. Understanding the background, motivations and expectations of volunteers helps this project, and the field of citizen science in plastic pollution research

Making citizen science count: best practices and challenges of citizen science projects on plastics in aquatic environments

There is considerable scientific and societal concern about plastic pollution, which has resulted in citizen science projects to study the scale of the issue. Citizen science is a cost-effective way to gather data over a large geographical range while simultaneously raising public awareness on the problem. Because the experiences of researchers involved in these projects are not yet adequately covered, this paper presents the findings from ten semi-structured qualitative interviews with researchers leading a citizen science project on micro- or macroplastics. Our results show it is important to specify the goal(s) of the project and that expertise on communication and data science is needed. Furthermore, simple protocols, quality control, and engagement with volunteers and the public are key elements for successful projects. From these results, a framework with recommendations was drafted, which can be used by anyone who wants to develop or improve citizen science projects.Science Communication and Societ

Gender Stereotypes in Science Education Resources: A Visual Content Analysis

More men are studying and working in science fields than women. This could be an effect of the prevalence of gender stereotypes (e.g., science is for men, not for women). Aside from the media and people’s social lives, such stereotypes can also occur in education. Ways in which stereotypes are visible in education include the use of gender-biased visuals, language, teaching methods, and teachers’ attitudes. The goal of this study was to determine whether science education resources for primary school contained gender-biased visuals. Specifically, the total number of men and women depicted, and the profession and activity of each person in the visuals were noted. The analysis showed that there were more men than women depicted with a science profession and that more women than men were depicted as teachers. This study shows that there is a stereotypical representation of men and women in online science education resources, highlighting the changes needed to create a balanced representation of men and women. Even if the stereotypical representation of men and women in science is a true reflection of the gender distribution in science, we should aim for a more balanced representation. Such a balance is an essential first step towards showing children that both men and women can do science, which will contribute to more gender-balanced science and technology fields.Science Communication and Societ

A Theory of Rational Attitude Polarization

Numerous experiments have demonstrated the possibility of attitude polarization. For instance, Lord, Ross & Lepper (1979) partitioned subjects into two groups, according to whether or not they believed the death penalty had a deterrent effect, and presented them with a set of studies on the issue. Believers and skeptics both become more convinced of their initial views; that is, the population polarized. Many scholars have concluded that attitude polarization shows that people process information in a biased manner. We argue that not only is attitude polarization consistent with an unbiased evaluation of evidence, it is to be expected in many circumstances where it arises. At the same time, some experiments do not find polarization, under the conditions in which our theory predicts the absence of polarization

Longitudinal study of motivation, attitude, and knowledge of citizen scientists monitoring plastic pollution on Dutch riverbank

Across the world, the number of citizen science projects focusing on plastic pollution is increasing. These projects often last for multiple years, which makes retaining volunteers challenging. However, our knowledge is limited regarding the effect of long-term involvement on citizen scientists’ motivation, attitude, and knowledge, especially for plastic pollution projects. Therefore, this study measured citizen scientists’ motivation, attitude, and knowledge in the Dutch Clean Rivers project before and during monitoring plastic pollution on riverbanks between 2017 and 2021.In total, 403 Clean Rivers participants completed a pre-survey, and a portion of them participated in one or multiple post-surveys throughout the years of monitoring. They were especially driven by Project Action motivations and Environmental motivations like tackling the source of pollution and doing something about the plastic soup, rather than being motivated by an Interest in Scientific Research like the desire to learn about scientific research. Project Action motivations increased significantly, especially within the first year of participation. Participants’ attitudes towards nature and science were initially high and did not increase significantly. Furthermore, while participants’ knowledge of plastic pollution was already high at the start, their knowledge of scientific research was not, and both increased significantly, especially in the first year of participation. The findings of this longitudinal study can contribute to improving the recruitment and retention of volunteers in current and future citizen science projects.Science Communication and Societ

Reasoning about objects in a natural history museum: the effect of complexity of questions on object labels

In natural history museums, a large part of the educational mission is to facilitate family learning with and about objects. Questions on object labels can play a role in this learning process. In the current study, we investigated the effect that different types of questions on object labels can have on the reasoning conversations among family members. We audio-recorded family conversations at an exhibit that included a fossilized dinosaur egg and a text label containing a question. Sixty-six families participated in three conditions differing in the level of complexity of the question on the label. We found that a question of moderate complexity facilitated the longest conversations, with the largest number of complex inferences, compared to the simpler and the more complex question. When reasoning, families most often used evidence from prior knowledge and other parts of the exhibition, but did not often relate to personal experiences. During the longer and more complex conversations, parents took up a larger role in the conversation, facilitating their family's reasoning process. We suggest that open-ended, moderately complex questions on labels can facilitate family reasoning conversations. Providing enough context within the surrounding exhibits and connecting to prior knowledge may help the reasoning process.Science Communication and Societ

From Hitler’s sweater to dinosaur fossils: An essentialist outlook on authenticity

Over the past two decades, the concept of authenticity has been the subject of considerable disagreement and debate. Although there have been attempts at reconciling various existing approaches, the literature is still short on a definition that is both practical and precise. This article proposes to make significant headway to that effect by suggesting that authenticity can be accounted for by an underlying psychological phenomenon known as essentialism. In making our case, we first provide an overview of present-day objectivist and constructivist positions and point out their shortcomings, after which we introduce an essentialist account of authenticity. We then argue essentialism has profound benefits over contemporary views and might be the best overarching framework we have, if we intend to reach consensus on the meaning of authenticity.Science Communication and Societ
