A main premise in school-based citizen science is that through their participation, students and teachers make meaningful contributions to the advancement of science. However, such initiatives may encounter difficulties in drawing on students' and teachers' knowledge and incorporating their voice in research processes and outcomes, partly due to established knowledge hierarchies in both science and schools. This research theoretically examines misuses of students' and teachers' knowledge in school-based citizen science that can be defined as an epistemic injustice. This term describes wrongful evaluations and considerations of people's knowledge or perspectives. Based on existing theoretical work on epistemic injustice, we first map out epistemic justifications for public participation in science and discuss deficiencies in current forms of citizen science that lead to the perseverance of epistemic injustice. Then, we identify and characterize four forms through which epistemic injustice may be manifested in school-based citizen science. Our theoretical analysis is complemented by illustrative examples from citizen science projects enacted in schools, demonstrating cases where epistemic injustice toward students and teachers was either instigated or mitigated. We discuss implications toward educational goals and the design of school-based citizen science, suggesting that epistemic injustice can be reduced or avoided by delegating authorities to schools, maximizing teacher and student agency, and leveraging schools' community connections. Overall, this research establishes theoretical grounds for examinations of epistemic injustice in school-based citizen science.</p>","PeriodicalId":48369,"journal":{"name":"Journal of Research in Science Teaching","volume":"62 5","pages":"1350-1387"},"PeriodicalIF":3.6,"publicationDate":"2024-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/tea.22006","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143846146","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Drawing from the dual synergy between translanguaging and science education on multimodalities and social justice agenda, this systematic review synthesized the key features of empirical research published from 2010 to 2023 that reported translanguaging practices in global K-12 formal and informal science education settings. The results indicated high heterogeneity in the studied socio-geographic landscapes and in the definition, implementation, and implication of translanguaging practices. Analysis of the science sense-making practices indicates some epistemic practices are more widely represented than others, with marginal global differences observed.

Course syllabi are one potential resource that can address these needs, and we asked to what extent biology syllabi are used for this purpose. We collected a national sample of introductory biology syllabi and used content analysis to determine if syllabi are learner-centered and whether they incorporate information on study behaviors, metacognition, and academic help-seeking. We found that most syllabi are not learner-centered, encourage ineffective study behaviors, did not include metacognition recommendations, and include incomplete academic help-seeking recommendations.

Studies carried out across diverse contexts converge in their commitment to fostering equity in science and engineering learning for linguistically marginalized learners. However, the rapid growth of this research area has exposed different approaches to conceptualizing “equity” itself. The purpose of this review of literature was to examine what equity approaches have undergirded research on translanguaging in US K–12 science and engineering education and whether these approaches vary over time and across contexts. We systematically analyzed studies (<i>N</i> = 15) using the four equity approaches articulated in a recent report by the National Academies of Sciences, Engineering, and Medicine (2022). Findings of our review indicate that, while studies aimed at increasing opportunity and access to high-quality science and engineering learning (Approach 1) and, to a lesser extent, identification and representation with science and engineering (Approach 2) were the two most prevalent equity approaches, studies focused on expanding what constitutes science and engineering (Approach 3) and seeing science and engineering as part of justice movements (Approach 4) were somewhat less common. Furthermore, justice-oriented approaches to equity (Approaches 3 and 4) were increasingly visible in the literature since 2020 as well as in research carried out in nontraditional educational contexts (e.g., out-of-school programs, classes outside of the core school subjects). Based on these findings, we propose the need for future research that (a) explicitly conceptualizes and operationalizes constructs related to equity (e.g., what is meant by “achievement” and how it is measured), (b) examines the possibilities and tensions associated with expanding what constitutes science and engineering in traditional educational contexts, (c) leverages the affordances of multiple STEM subjects for addressing justice issues impacting linguistically marginalized communities, and (d) iterates on the equity approaches themselves.</p>","PeriodicalId":48369,"journal":{"name":"Journal of Research in Science Teaching","volume":"62 1","pages":"15-48"},"PeriodicalIF":3.6,"publicationDate":"2024-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/tea.22012","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143114542","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To date, these beliefs have been predominantly investigated regarding teaching and learning in general or for a particular science subject (e.g., physics). It remains to be determined whether these beliefs are similar across different goals within a subject. The study reported addresses this question by investigating and comparing beliefs about teaching and learning regarding two prominent main goals of science education: content goals that refer to scientific phenomena, laws, theories, and disciplinary core ideas and procedural goals that refer to scientific procedures and practices. To that end, data from 170 German teachers were collected in 2019 and 2020 with an online questionnaire. After modeling the data and assessing the quality of measurement via Rasch analysis techniques, subsequent <i>t</i>-tests were employed to compare beliefs. Results reveal that science teachers' beliefs vary between both main goals. For instance, teachers believe that achieving procedural goals requires primarily doing science with lesser relevance of discussing and elaborating with students explicitly the rules and strategies for engaging appropriately in scientific practices (e.g., control of variables strategy). In contrast, teachers believe that for achieving content goals, explicit instruction about corresponding conceptual knowledge is of higher relevance. Furthermore, the analysis reveals differences in teachers' beliefs about their own abilities. Teachers typically believe they are more able to teach and deal with content goals compared with procedural goals. The differences reported may help to understand research on teachers' classroom practice and can inform teacher training and professional development.</p>","PeriodicalId":48369,"journal":{"name":"Journal of Research in Science Teaching","volume":"62 5","pages":"1388-1413"},"PeriodicalIF":3.6,"publicationDate":"2024-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/tea.22003","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143845885","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While integrating CT into science classrooms broadens exposure to computing, it may not be enough to ensure equitable participation in the science classroom. Equitable participation is crucial because providing students with an environment in which they are able to fully engage and participate in science and computing practices empowers students to learn and continue pursuing CT and science. To foreground equitable participation in CT-integrated curricula, we undertook a research project in which researchers and teachers examined teacher conceptualizations of equitable participation and how teachers design for equitable participation by modifying a lesson that introduces computational modeling in science. The following research questions guided the study: (1) What are teachers' conceptualizations of equitable participation? (2) How do teachers design for equitable participation through co-design of a CT-integrated unit? Our findings suggest that teachers conceptualized and designed for equitable participation in the context of a CT-integrated curriculum across three primary dimensions: accessibility, inclusion, and relevancy. Our contributions to the field of science teaching and learning are twofold: (1) obtaining an initial understanding of how teachers think about and design for equitable participation is crucial in order to support teachers in their pursuit of creating equitable learning experiences for CT and science learners, and (2) our findings show that we can study teacher conceptualizations and their design choices by examining specific modifications to a CT-integrated science curriculum.
