Much has been written about how effective nature of science instruction must have a significant explicit and reflective character. However, while explicitly drawing students’ attention to NOS issues is crucial, learning and teaching the NOS are essentially matters of conceptual change. In this article, how people learn and learners’ responses to the demands of conceptual change are used to explain how students may exit from instruction with fundamental NOS misconceptions left intact or only slightly altered, despite being explicitly and reflectively attended to more accurate ideas. The purpose of this concept paper is to set within a theoretical framework of learning, and bring some coherence to, what has rapidly become a large body of empirical research regarding effective NOS instruction. Toward these two ends, this article: (1) illustrates how a conceptual change framework can be used to account for learners’ responses to NOS instruction and what teachers might do to promote understanding NOS and transferring it to new contexts; (2) characterizes popularly advocated NOS instructional approaches along a continuum marked by increasing connection to the workings of science, and decreased ability to dismiss NOS lessons as extraneous to authentic science; and (3) proposes that NOS instruction would likely be more effective if teachers deliberately scaffolded classroom experiences and students’ developing NOS understanding back and forth along the continuum.  相似文献

Two fundamental questions about science are relevant for science educators: (a) What is the nature of science? and (b) what aspects of nature of science should be taught and learned? They are fundamental because they pertain to how science gets to be framed as a school subject and determines what aspects of it are worthy of inclusion in school science. This conceptual article re-examines extant notions of nature of science and proposes an expanded version of the Family Resemblance Approach (FRA), originally developed by Irzik and Nola (International handbook of research in history, philosophy and science teaching. Springer, Dordrecht, pp 999–1021, 2014) in which they view science as a cognitive-epistemic and as an institutional-social system. The conceptual basis of the expanded FRA is described and justified in this article based on a detailed account published elsewhere (Erduran and Dagher in Reconceptualizing the nature of science for science education: scientific knowledge, practices and other family categories. Springer, Dordrecht, 2014a). The expanded FRA provides a useful framework for organizing science curriculum and instruction and gives rise to generative visual tools that support the implementation of a richer understanding of and about science. The practical implications for this approach have been incorporated into analysis of curriculum policy documents, curriculum implementation resources, textbook analysis and teacher education settings.  相似文献

Scholars have argued that the history of science should be included in the science curriculum because it provides meaningful perspective about scientific concepts, processes, and context. This article begins with a review of efforts to humanize science education by including the history of science, and a review of the rationale for including the history of science in the science education curriculum. The authors then synthesize a conceptual framework for examining the role of the history of science in science education. The framework is organized around realms in the history of science: a) conceptual understanding, b) procedural understanding, and c) contextual understanding, and includes approximately 3 sub-elements within each realm. The framework has been used previously to study the inclusion of the history of science in high school physics textbooks (Wang 1998). In this study, it is used to examine the perceptions and practices of elementary and secondary school teachers in using the history of science in their classrooms. Thirty-eight teachers completed a questionnaire which used Likert scale items to assess their perception of the value of the history of science, and practice in using it in their classroom. A sub-set of teachers were then interviewed to understand the interconnection of these views in more detail. Teachers believe that the inclusion of the history of science should not be used for elementary school students. Teachers who believe in and practice the inclusion of the history of science identify many benefits for their students. However, they believe that it is difficult to include the procedural realm of understanding. The authors conclude that humanizing science isn't a matter of making it fun so much as making it a human and meaningful endeavor.  相似文献

This paper draws attention to basic philosophical perspectives which are of theoretical and methodological interest for science education, general education and curriculum research. It focuses on potential contributions philosophy class can offer if philosophy education opens up for science and for a collaboration of teachers in the context of post-compulsory education. A central educational goal is to connect basic philosophical skills with any curricular intellectual practice. This implies the possibility of crossing disciplinary boundaries. Hence, the present paper questions the disciplinary rigidity of education and aims at bridging the artificial gap between teaching philosophy and teaching science in order to enrich the individual school subjects involved. Towards this end, this article sketches out a conceptual framework for the issue of interdisciplinarity with regard to philosophy and science in upper secondary school. This framework takes into account aspects of the nature of science (NOS), history and philosophy of science (HPS) and the critical thinking approach which have significant implications for teaching. It aims to facilitate a basic understanding of the significant positive impact philosophy could have on improving scientific literacy as well as decision-making in general. I set forth methods of cross-curricular teaching which can promote innovation in education as interdisciplinarity already does in research since there is growing appreciation of collaboration and partnership between philosophy and science.

Understanding the nature of science (NOS) has long been a desired outcome of science education, despite ongoing disagreements about the content, structure, and focus of NOS expectations. Addressing the concern that teachers likely focus only on student learning expectations appearing in standards documents, this study examines the current state of NOS in science education standards documents from nine diverse countries to determine the overt NOS learning expectations that appeared, NOS statements provided near those learning expectations, but not identified as learning outcomes (such as chart column headers or footnotes), and NOS statements found in ancillary text (e.g., introductory material or appendices). Findings indicate that NOS ideas rarely occur as expectations for student learning and are far more commonly found in ancillary material. Moreover, consensus was not apparent in the overt learning outcomes for students. Given the well-documented poor state of NOS instruction and the consistent lack of NOS appearing in published curriculum materials, the NOS standards appearing in nearly all documents analyzed are unlikely to provide sufficient conceptual or pedagogical support for NOS to be accurately interpreted or translated into meaningful experiences for students.  相似文献

The inclusion of Nature of Science (NOS) in the science curriculum has been advocated around the world for several decades. One way of defining NOS is related to the family resemblance approach (FRA). The family resemblance idea was originally described by Wittgenstein. Subsequently, philosophers and educators have applied Wittgenstein’s idea to problems of their own disciplines. For example, Irzik and Nola adapted Wittgenstein’s generic definition of the family resemblance idea to NOS, while Erduran and Dagher reconceptualized Irzik and Nola’s FRA-to-NOS by synthesizing educational applications by drawing on perspectives from science education research. In this article, we use the terminology of “Reconceptualized FRA-to-NOS (RFN)” to refer to Erduran and Dagher’s FRA version which offers an educational account inclusive of knowledge about pedagogical, instructional, curricular and assessment issues in science education. Our motivation for making this distinction is rooted in the need to clarify the various accounts of the family resemblance idea.The key components of the RFN include the aims and values of science, methods and methodological rules, scientific practices, scientific knowledge as well as the social-institutional dimensions of science including the social ethos, certification, and power relations. We investigate the potential of RFN in facilitating curriculum analysis and in determining the gaps related to NOS in the curriculum. We analyze two Turkish science curricula published 7 years apart and illustrate how RFN can contribute not only to the analysis of science curriculum itself but also to trends in science curriculum development. Furthermore, we present an analysis of documents from USA and Ireland and contrast them to the Turkish curricula thereby illustrating some trends in the coverage of RFN categories. The results indicate that while both Turkish curricula contain statements that identify science as a cognitive-epistemic system, they underemphasize science as a social-institutional system. The comparison analysis shows results such as the “scientific ethos” category being mentioned by the Irish curriculum while “social organizations and interactions” category being mentioned by the Turkish curriculum. In all documents, there was no overall coherence to NOS as a holistic narrative that would be inclusive of the various RFN categories simultaneously. The article contributes to the framing of NOS from a family resemblance perspective and highlights how RFN categories can be used as analytical tools.  相似文献

In recent years, there has been upsurge of interest in the applications of interdisciplinary perspectives on science in science education. Within this framework, the implications of the so-called “economics of science” is virtually an uncharted territory. In this paper, we trace a set of arguments that provide a dialectic engagement with two conflicting agendas: (a) the broadening of science education to include the contextual positioning of science including economical dimensions of science, and (b) the guarding of the proliferation and reinforcement of those aspects of economics of science such as commodification of scientific knowledge that embraces inequity and restricted access to the products of the scientific enterprise. Our aim is broadly to engage, as science education researchers, in the debates in economics of science so as to investigate the reciprocal interactions that might exist with science education. In so doing, we draw out some recommendations whereby the goals of science education might provide as much input into the intellectual debates within philosophy of science on issues related to the commercialisation and commodification of scientific knowledge. We explore some implications of commodification of science in the context of modelling and argumentation in science education.  相似文献

Explicit instruction of the nature of science (NOS) may be problematic if the NOS is portrayed as either a solely a cognitive or discursive endeavor, overlooking other aspects of epistemology, such as aesthetic ways of knowing. Here the aesthetic stance refers to individual’s responses during reading as they create links between the text and their own lives, prompting personal and emotional connections. From an aesthetic orientation, exploring historical nonfiction science texts via literature circles allows alternative possibilities for participants to create personal connections to the NOS. This article presents practical techniques and theoretical rationales for teaching the NOS using literature circles and concluding thoughts regarding narrative pedagogy and research possibilities associated with this instructional approach in elementary science teacher education.  相似文献

Nature of science (NOS) is beginning to find its place in the science education in China. In a study which investigated Chinese science teacher educators’ conceptions of teaching NOS to prospective science teachers through semi-structured interviews, five key dimensions emerged from the data. This paper focuses on the dimension, NOS content to be taught to prospective science teachers. Among a total of twenty NOS elements considered by the Chinese science teacher educators to be important ideas to be taught, five were suggested by no less than a half of the educators. They are (1) empirical basis of scientific investigation, (2) logics in scientific investigation, (3) general process of scientific investigation, (4) progressive nature of scientific knowledge, and (5) realist views of mind and natural world. This paper discusses the influence of Marxism, a special socio-cultural factor in China, on Chinese science teacher educators’ conceptions of NOS content to be taught to prospective science teachers. We argue the importance of considering ideological traditions (mainly those in general philosophy and religion) when interpreting views of NOS or its content to be taught in different countries and regions and understanding students’ conceptual ecology of learning NOS.  相似文献

Developing pre-service science teachers’ epistemic insight remains a challenge, despite decades of research in related bodies of work such as the nature of science (NOS) in science education. While there may be numerous aspects to this problem, one critical element is that the NOS is a meta-concept that demands higher-order cognitive skills. One possible strategy to facilitate pre-service teachers’ understanding of epistemic aspects of science is visualisation. Visual representations of objects and processes can be tools for developing and monitoring understanding. Although the NOS and visualisation literatures have been studied extensively, the intersection of these bodies of literatures has been minimal. Incorporating visual tools on the NOS in teacher education is likely to facilitate teachers’ learning, eventually impacting their students’ learning of the NOS. The objective of this paper is to illustrate how the visual tools of scientific knowledge and practices aspects of the NOS can be integrated in science teacher education in order to develop pre-service teachers’ epistemic insight. The paper presents an empirical study that incorporated visual tools about the NOS in primary science teacher education. Data on 14 pre-service teachers’ are presented along with in-depth case studies of 3 pre-service teachers illustrating the influence of the teacher education intervention. The qualitative analysis of visual representations before and after the intervention as well as verbal data suggests that there was improvement in pre-service teachers’ perceptions of the NOS. Implications for future research on visualisation of the NOS are discussed.  相似文献

This study examined the inclusion of nature of science (NOS) in popular science writing to determine whether it could serve supplementary resource for teaching NOS and to evaluate the accuracy of text mining and classification as a viable research tool in science education research. Four groups of documents published from 2001 to 2010 were analyzed: Scientific American, Discover magazine, winners of the Royal Society Winton Prize for Science Books, and books from NSTA’s list of Outstanding Science Trade Books. Computer analysis categorized passages in the selected documents based on their inclusions of NOS. Human analysis assessed the frequency, context, coverage, and accuracy of the inclusions of NOS within computer identified NOS passages. NOS was rarely addressed in selected document sets but somewhat more frequently addressed in the letters section of the two magazines. This result suggests that readers seem interested in the discussion of NOS-related themes. In the popular science books analyzed, NOS presentations were found more likely to be aggregated in the beginning and the end of the book, rather than scattered throughout. The most commonly addressed NOS elements in the analyzed documents are science and society and empiricism in science. Only one inaccurate presentation of NOS were identified in all analyzed documents. The text mining technique demonstrated exciting performance, which invites more applications of the technique to analyze other aspects of science textbooks, popular science writing, or other materials involved in science teaching and learning.  相似文献

This paper articulates the importance of epistemological beliefs (EBs) and draws a parallel between EBs literature in educational psychology and nature of science (NOS) literature in science education. The paper stresses that EBs in science and NOS ideas have common ground and they can be best improved through explicit-reflective instruction informed by conceptual change theory. The paper concludes that future studies should explore the factors that mediate the development of EBs in science and NOS ideas rather than documenting the changes in students’ and teachers’ EBs in science and NOS ideas after explicit-reflective instruction through pre- and post assessments.  相似文献

Communication is an important part of scientific practice and, arguably, may be seen as constitutive to scientific knowledge. Yet, often scientific communication gets cursory treatment in science studies as well as in science education. In Nature of Science (NOS), for example, communication is rarely mentioned explicitly, even though, as will be argued in this paper, scientific communication could be treated as a central component of NOS. Like other forms of communication, scientific communication is socially and symbolically differentiated. Among other things, it encompasses technical language and grammar, lab communications, and peer reviews, all of which will be treated in this paper in an attempt to engage on an empirical and theoretical level with science as communication. Seeing science as a form of communicative action supplements the epistemological view of science that is standard to both NOS and the philosophy of science. Additions to the seven NOS aspects on Lederman’s (Handbook of research on science education. Lawrence Erlbaum, Mahwah, pp. 831–879, 2007) list are put forward as well as preliminary thoughts on the inclusion of scientific communication into NOS instruction.  相似文献

The purpose of this study was twofold: (a) develop a conceptual framework for environmental science literacy; and consequently (b) examine the potential of science standards/curricula to prepare environmentally literate citizens. The framework comprised four pillars: science content knowledge, scientific inquiry, nature of science (NOS), and socioscientific issues (SSI). A conceptual understanding of these pillars as interconnected was presented and justified. Then the developed framework was used to examine the potential of the Qatari science standards to prepare environmentally literate citizens. Results showed that the secondary Qatari science standards generally take up the pillars of science content and scientific inquiry in an explicit manner. The NOS pillar is rarely addressed, while the SSI pillar is not addressed in the objectives and activities in a way that aligns with the heavy emphasis given in the overall aims. Moreover, the connections among pillars are mostly manifested within the activities and between the science content and scientific inquiry. The objectives and activities targeting the environment were less frequent among the four pillars across the Qatari standards. Again, the connections related to the environment were less frequent in conformity with the limited environmental objectives and activities. Implications from this study relate to the need for the distribution of the four pillars across the standards as well as the presentation of the different pillars as interconnected.  相似文献

Considerable work over many years has explored the contribution technology can make to science learning, at all levels of education. In the school sector, historically this has focused on the use of fixed, desktop-based or semi-mobile laptop systems for purposes such as experiment data collection or analysis, or as a means of engaging or motivating interest in science. However, the advent of mobile devices such as iPads supported by a huge array of low or no cost apps, means that new opportunities are becoming available for teachers to explore how these resources may be useful for supporting ‘hands on’ science learning. This article reports outcomes from a study of primary (elementary) school students’ use of a series of apps integrated with practical science activities, in a topic exploring Energy concepts. It used an innovative display capture tool to examine how the students used the apps and features of their iPads to scaffold their practical work at different stages during the experiments. Results identify device functions and app-based scaffolds that assisted these students to structure their experiments, understand procedures, think about the influence of variables and communicate and share outcomes. However, they also discovered limitations in the apps’ ability to support conceptual knowledge development, identifying the critical role of teachers and the importance of task structure and design to ensuring conceptual knowledge objectives are met.  相似文献
