Justice-centered STEM education engages all students in multiple STEM subjects, including data science and computer science, to explain and design solutions to societal challenges disproportionately impacting minoritized groups. We articulate the affordances of justice-centered STEM education for one minoritized student group that has been traditionally denied meaningful STEM learning: multilingual learners (MLs). Justice-centered STEM education with MLs leverages the assets they bring to STEM learning, including their transnational experiences and knowledge as well as their rich repertoire of meaning-making resources. In this position paper, we propose our conceptual framework to chart a new research agenda on justice-centered STEM education to address societal challenges with all students, especially MLs. Our conceptual framework incorporates four interrelated components by leveraging the convergence of multiple STEM disciplines to promote justice-centered STEM education with MLs: (a) societal challenges in science education, (b) justice-centered data science education, (c) justice-centered computer science education, and (d) justice-centered engineering education. The article illustrates our conceptual framework using the case of the COVID-19 pandemic, which has presented an unprecedented societal challenge but also an unprecedented opportunity to cultivate MLs' assets toward promoting justice in STEM education. Finally, we describe how our conceptual framework establishes the foundation for a new research agenda that addresses increasingly complex, prevalent, and intractable societal challenges disproportionately impacting minoritized groups. We also consider broader issues pertinent to our conceptual framework, including the social and emotional impacts of societal challenges; the growth of science denial and misinformation; and factors associated with politics, ideology, and religion. Justice-centered STEM education contributes to solving societal challenges that K-12 students currently face while preparing them to shape a more just society.</p>","PeriodicalId":48369,"journal":{"name":"Journal of Research in Science Teaching","volume":"62 5","pages":"1202-1231"},"PeriodicalIF":3.6,"publicationDate":"2024-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143846253","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using the dual lenses of socio-spatial relationality and politicized trust, we explore how the socio-spatial relationality of place, materials, and educator–youth interactions allowed for the shifting of power dynamics that were foundational to supporting youth in navigating a coding process that centered who they were and their interests, in the moment. We employ participatory design research aimed at reducing power dynamics by remediating who has power within a setting, grounded in dismantling and disrupting traditional power hierarchies through actively involving the community in the design process. We present two case studies that map the learning trajectories of Donovan and Jabria, two middle-school aged Black boys. Their learning trajectories include the following phases: tensions related to coding with Scratch, pivotal interaction with the educator, and development of critical agency. We unpack how the socially produced space supported Donovan, Jabria, and Worsley to critically read the world of coding, rewrite coding through political action, and establish politicized trust. Throughout this process, we see through Donovan and Jabria's interactions they were constantly editing and producing their interactions with coding which led to newly created learning opportunities by developing their critical agency in coding. Four main points were identified: continuous access to materials, sustained engagement to reimagine possibilities, understanding that all disengagement is not equal, and being explicit in communicating expectations followed by concrete action. Across these points, the salience of relational politicized trust between educator and youth was a cross cutting thread.</p>","PeriodicalId":48369,"journal":{"name":"Journal of Research in Science Teaching","volume":"62 4","pages":"1073-1102"},"PeriodicalIF":3.6,"publicationDate":"2024-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/tea.21992","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143646307","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}

However, preservice teachers (PSTs) can have limited opportunities to develop CKT, and little is known about how to support PST CKT development in elementary science teacher preparation. In our work, we developed instructional materials (i.e., “CKT Packets”) intended to support teacher educators (TEs) in developing elementary PSTs' CKT for one content area—matter and its interactions. We facilitated a professional learning community for TEs to support their learning how to implement the materials in their courses.

Nesting PSTs within their TEs' courses, and controlling for PSTs' prior CKT, engagement time on the assessments, prior coursework, and TE time-invariant effects, we found preliminary evidence that PSTs achieved greater CKT when TEs implemented more CKT Packets. Salient factors that we hypothesize influenced TEs' productive uses of CKT Packets included disruptions to courses/contexts, TEs' sources of motivation for implementing Packets, TEs' entry points for the alignment of curricular materials with existing topics and pedagogical course emphases, TEs' approaches for first-time use of curricular materials, and TEs' experiences with the instructional routines of the Packets.

Here, we examined the professional teacher identity development of 13 science teachers as they collaborated in networked professional learning communities (PLCs) to implement and revise a culture-setting unit focused on the science of COVID and engaging in collaborative inquiry cycles to identify and refine justice-centered ambitious science teaching (JuST) practices in classrooms. These JuST practices are conceptualized as a synthesis of justice-centered pedagogies and ambitious science teaching. To accomplish our research aims, we drew on qualitative methods, where we relied on transcribed video recordings of 21 PLC meetings and three transcribed end-of-year focus group interviews of two PLCs (i.e., 13 secondary science teachers, mostly white) across a year-long period. As a result of our analyses, we identified how professional learning arranged through PLCs, culture-setting units, and collaborative inquiries supported professional JuST identity development by, among other affordances, providing space for the critical and emotional work of learning to discuss race, affording teachers strategies for getting to know their students and the assets they bring to classrooms, and recognition and positioning of teachers as professionals capable of identifying or developing, refining, and contributing to knowledge about JuST science teaching and learning. Challenges identified included, among others, identifying how the culture-setting units could be effectively integrated into existing curriculum maps and the uneven implementation support from administrators. In the end, what is revealed helps better conceptualize how engaging teachers in PLCs around tasks like curriculum implementation and refinement or collaborative inquires support professional JuST identity development and how such experiences can be more carefully negotiated.</p>","PeriodicalId":48369,"journal":{"name":"Journal of Research in Science Teaching","volume":"62 4","pages":"1040-1072"},"PeriodicalIF":3.6,"publicationDate":"2024-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143645684","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Undergraduate students with disabilities are underrepresented in STEM, and disciplines requiring major field components are some of the least diverse, at least in part because fieldwork has been traditionally viewed as hard, physical, and masculine. Disability Studies in Education (DSE) frames the research questions, inclusion criteria and results. Studies were coded by disability model used, barriers and strategies to accessibility in field science, and meaningful involvement of persons with disabilities in research on fieldwork education. Although most studies asserted a view of disability as a social, cultural, and political phenomenon, some deficit language and interpretations persisted. Few studies included author positionality, and even fewer disclosed author disability status. The main instructional recommendations emphasize flexibility and adaptability, presuming student competence and making small-scale changes consistently over time. Multiple studies emphasize the need for proactive planning, including robust contingency plans, and explaining how these plans can negate the need for complex modification. Twenty-four additional non-empirical studies are identified as resources for discipline-specific guides and checklists for inclusive fieldwork. We conclude that important steps are being taken to investigate and critique barriers to fieldwork participation for students with disabilities, but there is still much work to be done in addressing systemic barriers beyond the control of individual instructors.</p>","PeriodicalId":48369,"journal":{"name":"Journal of Research in Science Teaching","volume":"62 4","pages":"1006-1039"},"PeriodicalIF":3.6,"publicationDate":"2024-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/tea.21989","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143645747","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}

As such, teachers are being asked to possess or take up conceptions of science that challenge the status quo. Are teachers making these shifts? Do they conceive of science in these anti-traditional ways? To explore this matter, I developed a conceptual framework around five key science topics: (1) Revision/Static; (2) Scientific Method; (3) Objective/Subjective; (4) Society and Culture; and (5) Critical Space, then surfaced traditional and anti-traditional conceptions regarding each topic drawn from science standards and prior literature. I operationalized this framework to critically analyze 20 secondary science teachers' discourse to determine whether they aligned with a traditional science ideology, an anti-traditional ideology, or somewhere in the middle (conflicting ideology). I found that for the most part participants demonstrated alignment with the anti-traditional conception when it came to the first two topics, however, when it came to the latter three topics, tensions arose and there was noticeably less consensus. As participants discussed concepts related to the latter topics, which I argue are more closely related to society, culture, and humanness, they demonstrated strikingly greater alignment with the traditional conceptions. These findings have implications for science teachers' capacity to teach science with NOS and CRST in mind. Findings also highlight key areas of consideration for teacher educators, curriculum developers, and policymakers when guiding teachers on the journey to attend to NOS and CRST.</p>","PeriodicalId":48369,"journal":{"name":"Journal of Research in Science Teaching","volume":"62 2","pages":"525-552"},"PeriodicalIF":3.6,"publicationDate":"2024-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143114239","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As an alternative, slightly longer engagement exceeding 72 h, coupled with sustained support over 6 months, has proven to be the second most effective option for PD. Furthermore, an active learning approach within PD programs (ḡ = 0.794, s.e. = 0.066, 95% <i>CI</i> [0.656, 0.926]) has emerged as a pivotal influence on PD effectiveness.

This study captures the firsthand experiences of marginalized domestic and international women (Black, Hispanic/Latina, Asian, Pacific Islander, and Indigenous) pursuing graduate degrees in chemistry. We conducted semi-structured interviews with 29 participants to understand how their social identities might impact the development of their science identities. Intersectionality and the Science Identity Model informed both the interview guide and the interpretation of our data. Deductive and inductive coding, constant comparative analysis, and thematic analysis were used to examine the interplay between participants' identities and experiences. We found that recognition had a critical impact on women's science identities. Results show that participants received more positive recognition than negative from their academic community. The participants who received mostly positive recognition developed research, teaching, and altruistic science identities. Most of the positive recognition was associated with research accomplishments, which is not surprising since doctoral programs in chemistry focus primarily on research training. Conversely, the participants who received mostly negative forms of recognition developed disrupted science identities. These women described being tokenized, taken advantage of, and having their accomplishments dismissed because of their gender, race, and ethnicity.
