Using video recordings of students and learning assistants interacting in a variety of contexts including remote, in-person, and hybrid classrooms in introductory chemistry and physics at two universities, we developed an analytical framework that can characterize learning in the moment of interaction, is sensitive to different kinds of learning, and can be used to compare interactions.

The basis of the technology becomes the basis of what it finds. There are correlations between questions that designers face in sampling and gathering data that is rich with context, and those that large-scale machine learning faces in how it approaches the rich context and subjectivity within its training data. AI, however, processes enormous amounts of data and produces models that can be explored. This makes its form of pragmatic inquiry that is amenable to optimisation. Finally, the paper explores implications for education that stem from how we apply AI to pedagogy and explanation, suggesting that the availability of AI-generated explanations and materials may also push pedagogy in directions of pragmatism: the evidence that explanations are effective may precede explorations of why they should be.</p></div>","PeriodicalId":771,"journal":{"name":"Science & Education","volume":"34 2","pages":"807 - 824"},"PeriodicalIF":3.1,"publicationDate":"2024-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s11191-024-00517-z.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140624173","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}

Considered were approaches that science teachers can use in science classes in secondary schools. They were analyzed and discussed against the backdrop of critical pedagogy by Paulo Freire and the educational theory by Hannah Arendt, which constitutes a novelty in science education research. The review used meta interpretation combined with systematic searches in the ERIC database. It is, thus, limited to works published in English. A total of 930 articles (2013–2021) were identified out of which 64 were fully analyzed. The analysis shows that most approaches strive to provide more equal access to the existing science knowledge and structures of the community. This corresponds to the introduction to the “old world” in a conservative interpretation of Arendt's term. I argue that in addition, it is necessary to employ a more radical interpretation of the “old world” as fundamentally plural which is done in translanguaging and grappling with racism. Further, the transformative nature of science education needs to be strengthened in terms of Freire's critical pedagogy and Arendt's concept of natality. This means allowing students to become aware of oppressive structures to induce change. Only youth participatory science, youth participatory action research, and grappling with racism explicitly aim for this. This shows that nuanced perspectives on equity in science education are needed.</p>","PeriodicalId":771,"journal":{"name":"Science & Education","volume":"108 4","pages":"1191-1221"},"PeriodicalIF":4.3,"publicationDate":"2024-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/sce.21868","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140587434","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}

The data of this exploratory study were collected through clinical interviews and analyzed both qualitatively and quantitatively. The findings indicated that preschoolers’ mean score improved in both conditions for each subject domain, (probably) as a result of their participation in the experimentation phase of the interviews, across all domains and conditions. No statistically significant difference in preschoolers’ learning between the two conditions was found in the balance beam domain. In the sinking/floating domain, VM were found to be more conducive to preschoolers’ learning than PM, whereas in the springs domain PM were found to have enhanced preschoolers’ learning more than VM did. These findings have important implications for science teaching and learning in the early childhood years.

ChatGPT, a state-of-the-art (SOTA) AI released in November 2022, has attracted global interest for its exceptionally high performance in generating human-like natural language answers to almost any questions a user queries. Its ability to generate knowledge raises questions about what human knowledge means in science education in the digital age. The researchers of this study consider ChatGPT as an epistemic agent that is capable of generating new scientific knowledge and as an eligible interviewee to provide data for the study of AI and human episteme. The researchers interviewed ChatGPT and analysed its responses to questions about the future of human epistemic agency in science education to elicit ontological and relational implications between humans and AI. Based on ChatGPT’s articulations, it was suggested that SOTA AI-generated knowledge is <i>non-bodied</i>, <i>robust</i>, and <i>detached</i>, which can be summarised as <i>automatous</i>. In contrast, it was suggested that human-generated knowledge is <i>embodied</i>, <i>value-laden</i>, and <i>engaged</i>, which can be summarised as <i>personal</i>, in light of Michael Polanyi’s thoughts. As a result, this study insists that there are still unique characteristics of human-generated scientific knowledge compared to those of AI.

While providing access and opportunity for research experiences is an important equity endeavor, a focus solely on broadening participation neglects the role of institutions in perpetuating hegemonic views of science.

Although many participants successfully disrupted damaging discourses of science as elite and disconnected, as well as discourses of accountability and the role of standardized testing, they were not able to disrupt deficit discourses that resulted in positioning themselves as outside of their students' worlds, often as saviors.

Transferring this practice from expert settings to the classroom is invaluable yet challenging. Teachers often perceive struggles as incidental, negative, and uncomfortable, assuming they stem from students' deficiencies in knowledge or understanding, which they feel compelled to promptly address to progress. While some empirical research has explored the role of scientific uncertainties in driving productive student struggle, few studies have explicitly examined or provided a framework to unpack scientific uncertainty as it manifests in the classroom, including the sources that lead to student struggle and how teachers can manage it effectively. In this position paper, we elucidate the importance of incorporating scientific uncertainties as pedagogical resources to foster student struggles through uncertainty from three perspectives: scientific literacy, student agency, and coherent trajectories of sensemaking. To develop a theoretical framework, we consider scientific uncertainty as a resource for productive struggle in the sensemaking process. We delve into two types (e.g., conceptual, epistemic), four sources (e.g., insufficiency, ambiguity, incoherence, conflict), and three desirability considerations (e.g., relevance, timing, complexity) of scientific uncertainties in student struggles to provide a theoretical foundation for understanding what students struggle with, why they struggle, and how scientific uncertainties can be effectively managed by teachers.

We thereby focus on specific types of conceptualizations of the greenhouse effect that have been identified in previous research and furthermore investigate the coherency of them. To do so, we analyzed answers of <i>N</i> = 604 grade 11 students in Austria and Germany and interpreted them from different theoretical perspectives.

However, especially for a reflection-based framework of the greenhouse effect, our results demonstrate that students' conceptions show some form of coherency. We argue that our results can inform the development of effective teaching strategies that address students' existing knowledge and alternative conceptions. In terms of practical implications, the findings suggest that teaching strategies should provide opportunities for students to integrate their knowledge pieces into a more coherent understanding of the greenhouse effect.
