This article adopts a conceptual approach to define cooperation and its key features, based on a systematic literature review. This approach allowed us to design 21 features of cooperation and build indicators that enable us to measure these features between citizen scientists. These 21 features of cooperation allow us to account for the plurality of citizen scientists’ meanings and practices in SSH. The indicators, which we refer to as “cooperation analytics,” can be deployed in a digital platform to provide direct and constant feedback to the actors themselves while their project is still under development. These analytics can serve as a tool for reflexivity, that is, to reflect on the assumptions that we make when producing knowledge, where cooperation is considered as a learning process under continuous revision and not as a criterion for conformity. Ultimately, cooperation analytics contribute to establishing new conventions for an enhanced citizen science, and to providing accountability and robustness in knowledge production and policymaking.","PeriodicalId":514738,"journal":{"name":"Citizen Science: Theory and Practice","volume":"34 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141682325","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are now software tools that facilitate the development of citizen science apps. However, apps developed with these tools rely on individual human skills to correctly collect useful data. Machine learning (ML)–aided apps provide on-field guidance to citizen scientists on data collection tasks. However, these apps rely on server-side ML support, and therefore need a reliable internet connection. Furthermore, the development of citizen science apps with ML support requires a significant investment of time and money. For some projects, this barrier may preclude the use of citizen science effectively. We present a platform that democratizes citizen science by making it accessible to a much broader audience of both researchers and participants. The SmartCS platform allows one to create citizen science apps with ML support quickly and without coding skills. Apps developed using SmartCS have client-side ML support, making them usable in the field, even when there is no internet connection. The client-side ML helps educate users to better recognize the subjects, thereby enabling high-quality data collection. We present several citizen science apps created using SmartCS, some of which were conceived and created by high school students.","PeriodicalId":514738,"journal":{"name":"Citizen Science: Theory and Practice","volume":"32 8","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141685201","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Unlike many biodiversity programs, which typically emphasize programmatic outcomes, this study examined how Blue Thumb, an Oklahoma water quality citizen science program, influences volunteer behaviors, interests, and motivations using an explanatory survey based on Phillips et al.’s (2018) evaluation framework. Although there were no significant differences in behaviors and interests between new and experienced volunteers (N = 74), motivations varied significantly, distinguishing between intrinsic and extrinsic reasoning. Blue Thumb volunteers already displayed pro-environmentalism and strong scientific interests before joining, and these traits persisted rather than being cultivated through participation. The study’s insights informed Blue Thumb’s future volunteer recruiting and retention strategies. While contributing to research utilizing a common framework, future studies should incorporate qualitative methods to provide context for a deeper understanding of the quantitative findings.","PeriodicalId":514738,"journal":{"name":"Citizen Science: Theory and Practice","volume":"63 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141687146","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.\u0000In 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.","PeriodicalId":514738,"journal":{"name":"Citizen Science: Theory and Practice","volume":"17 10","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140982384","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Science Products Inventory (SPI) is one tool to assist with participatory science evaluation that extends beyond scientific outputs such as publications. Its use cases were limited to a cohort of projects during its initial development, so here we explored its utility and flexibility for use cases across multiple US federally-funded participatory science projects. We examined the tool’s formative and longitudinal utility, accessibility, and adaptability with contributory projects spanning different sizes, scopes, and goals. We found that the tool was easily customizable, making it suitable for individual project needs, including meeting the needs of funders for evaluation. It was easy to use, making it suitable for data gathering by non-expert evaluators, and it enabled practitioners to reflect on ways to enhance a project’s impact. We also found it useful for comparing evaluation data over time and between projects. Ultimately, citizen science includes elements across various dimensions that can be examined using quantitative indicators—like those in the SPI—and qualitative means. A combination of evaluation approaches could be appropriate for individual project goals and stakeholders, but we show how the simplicity and customizability of the SPI can provide benefits across a range of projects and programs.","PeriodicalId":514738,"journal":{"name":"Citizen Science: Theory and Practice","volume":"19 44","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141020205","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We explored how traits of orb weaving spiders impact data in iNaturalist, using the invasive Jorō spider as a case study. This species is an outlier among orbweavers due to its large size and bright coloration, and was the most frequently reported species, with the most identifications and research-grade observations. It was also reported by less experienced users on average, highlighting its potential role as a gateway species into community science participation. This bias towards large, flashy orbweaver species suggests underrepresentation of smaller, drab species. Given the increasing importance of open access digital biodiversity records, we encourage researchers to engage more with the iNaturalist community and contribute their expertise in improving the data quality wherever possible.","PeriodicalId":514738,"journal":{"name":"Citizen Science: Theory and Practice","volume":"30 24","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140659954","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this case study, we examined several factors relating to self-efficacy and skill growth in STEM and non-STEM majors in life science courses of different levels at one university. Four life science classes in Fall 2022 (n = 109 students) voluntarily participated in a self-guided pollinator training module. Motivations, previous awareness, participation, and self-efficacy and self-identification for citizen science participation and for general scientific inquiry were assessed through pre- and post-surveys before and after module training. Students characterized themselves as STEM or non-STEM majors to understand self-identity. In having students self-report their identity in STEM, we found a trend (79.2%) of natural resource and agricultural majors ranking themselves as non-STEM. Across all participants, we observed a significant increase for learning outcomes between pre- and post-survey results (ɑ = 0.05). Self-reported non-STEM students showed a positive trend between surveys across survey questions. In comparison, self-reported STEM students showed very little increase across surveys but ranked highly in both pre- and post-survey results (mean = 3.42 out of 4). Overall, our findings suggest that even small-scale citizen science–based projects may increase students’ familiarity with concepts based in scientific inquiry and meet learning outcomes benefitting the goals of both higher education and citizen science initiatives.","PeriodicalId":514738,"journal":{"name":"Citizen Science: Theory and Practice","volume":"78 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140239695","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, data generated from such projects can be considered “use-agnostic.” Nevertheless, such projects can yield important insights about species distributions. Many of these projects use a class-based data schema, whereby contributors must supply a species identification. This can limit participation if contributors are not confident in their identifications, and can introduce data quality issues if species identification is incorrect. Some projects, such as iNaturalist, circumvent this with crowdsourced species identifications based on contributed photographs, or by grading confidence in the data based on attributes of the sighting and/or contributor. An alternative to a class-based data schema is an open-ended (instance-based) one, where contributors are free to identify their sighting at whatever taxonomic resolution they are most confident, and/or describe the sighting based on attributes. This can increase participation (data completeness) and have the benefit of adding additional (and sometimes unexpected) information. The regionally-focused citizen science website NLNature.com was designed to experimentally examine how class-based versus instance-based schema affected contributions and data quality. Here, we show that the instance-based schema yielded not only more contributions, but also several of ecological importance. Thus, allowing contributors to supply natural history information at a level familiar to them increases data completeness and facilitates unanticipated contributions.","PeriodicalId":514738,"journal":{"name":"Citizen Science: Theory and Practice","volume":"6 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140439231","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Still, the intention to educate citizens sometimes prevails over an open and honest exchange. Because of this overemphasis on education, researchers may more easily label lay opinions invalid if uninformed or based on distorted beliefs. Our experience with uninformed and poorly informed (UPI) opinions in an online public engagement initiative (the DNA Debate) has taught us to think differently. First, UPI opinions might be ethically instructive, provided that one searches for the implicit message participants try to convey related to their values, fears, or needs. Since there will always be less informed or uninformed citizens, that would avoid rejecting their voices. Second, UPI opinions may highlight misconceptions in the general population for which more targeted education is necessary. This article is an invitation to reflect ethically on why and how researchers should deal with UPI opinions, illustrated by quotes from the DNA Debate.","PeriodicalId":514738,"journal":{"name":"Citizen Science: Theory and Practice","volume":"152 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139842722","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Dengue alone is endemic in more than 100 countries and causes more than 96 million symptomatic cases and approximately 40,000 deaths annually. The recent surge in arboviral disease outbreaks, coupled with the World Health Organization’s newly published vector control guidelines, accentuates the imperative to understand the dispersion of disease-carrying mosquitoes across diverse spatial and temporal scales. However, traditional surveillance mechanisms often fall short because of workforce limitations, logistical complexities, jurisdictional boundaries, and budgetary constraints, especially in low- and low-middle-income countries. In this article, we systematically report the design, implementation, and iterative enhancement of a groundbreaking school-based citizen science initiative for augmenting mosquito surveillance in the Solomon Islands. Key reflections encompass the initiative’s role in supporting routine government-led disease vector monitoring, sustainability through integration and fostering participant engagement, and the amalgamation of citizen-collected data with government surveillance activities. The article also discusses the impact of the citizen science initiative with regard to the Solomon Islands’ pursuit of the Sustainable Development Goals. Our findings underscore the potential of citizen science methods to support and extend public health surveillance activities and to serve as a community-engagement-for-behaviour-change tool in resource-constrained contexts.","PeriodicalId":514738,"journal":{"name":"Citizen Science: Theory and Practice","volume":"323 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139842795","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
