There is wide consensus that learning in science must be considered a process of conceptual change rather than simply information accrual. There are three perspectives on students’ conceptions and conceptual change in science that have significant presence in the science education literature: students’ ideas as misconceptions, as coherent systems of conceptual elements, and as fragmented knowledge elements. If misconceptions, systems of elements, or fragments are viewed implicitly as “regular things”, these perspectives are in opposition. However, from a complex dynamic systems perspective, in which students’ conceptions are viewed as dynamically emergent structures, the oppositions are lessened, and the integrated view has significant implications for theory and practice. 相似文献

Although the concept of “rural” is difficult to define, rural science education provides the possibility for learning centered upon a strong connection to the local community. Rural American adolescents tend to be more religious than their urban counterparts and less accepting of evolution than their non-rural peers. Because the status and perception of evolutionary theory may be very different within the students’ lifeworlds and the subcultures of the science classroom and science itself, a cultural border crossing metaphor can be applied to evolution teaching and learning. This study examines how a teacher may serve as a cultural border crossing tour guide for students at a rural high school as they explore the concept of biological evolution in their high school biology class. Data collection entailed two formal teacher interviews, field note observations of two biology class periods each day for 16 days during the Evolution unit, individual interviews with 14 students, student evolution acceptance surveys, student evolution content tests, and classroom artifacts. The major findings center upon three themes regarding how this teacher and these students had largely positive evolution learning experiences even as some students continued to reject evolution. First, the teacher strategically positioned himself in two ways: using his unique “local” trusted position in the community and school and taking a position in which he did not personally represent science by instead consistently teaching evolution “according to scientists.” Second, his instruction honored local “rural” funds of knowledge with respect to local knowledge of nature and by treating students’ religious knowledge as a form of local expertise about one set of answers to questions also addressed by evolution. Third, the teacher served as a border crossing “tour guide” by helping students identify how the culture of science and the culture of their lifeworlds may differ with respect to evolutionary theory. Students negotiated the cultural borders for learning evolution in several ways, and different types of border crossings are described. The students respected the teacher’s apparent neutrality, sensitivity toward multiple positions, explicit attention to religion/evolution, and transparency of purposes for teaching evolution. These findings add to the current literature on rural science education by highlighting local funds of knowledge for evolution learning and how rural teachers may help students navigate seemingly hazardous scientific topics. The study’s findings also add to the current evolution education literature by examining how students’ religious perspectives may be respected as a form of expertise about questions of origins by allowing students to examine similarities and differences between scientific and religious approaches to questions of biological origins and change. 相似文献

The notion of “science for all” suggests that all students—irrespective of achievement and ability—should engage in opportunities to understand the practice and discourse of science. Improving scientific literacy is an intrinsic goal of science education, yet current instructional practices may not effectively support all students, in particular, students with special needs. Argument‐based inquiry approaches, such as the Science Writing Heuristic (SWH), require all students to construct their scientific understandings by engaging in investigations and negotiating their ideas in multiple contexts, such as discussions and writing. Various SWH studies demonstrated that students engaged in appropriating the language, culture, practice, and dispositions of science generally improved their critical thinking and standardized test scores. The implementation of such an approach has several implications for science and special education research and practice, including how learning environments should be established to encourage the inclusion of all students’ ideas, as well as how scaffolded supports can and should be used to support science learning. 相似文献

This article intends to show that the defense of “understanding” as one of the major goals of science education can be grounded on an anti-reductionist perspective on testimony as a source of knowledge. To do so, we critically revisit the discussion between Harvey Siegel and Alvin Goldman about the goals of science education, especially where it involves arguments based on the epistemology of testimony. Subsequently, we come back to a discussion between Charbel N. El-Hani and Eduardo Mortimer, on the one hand, and Michael Hoffmann, on the other, striving to strengthen the claim that rather than students’ belief change, understanding should have epistemic priority as a goal of science education. Based on these two lines of discussion, we conclude that the reliance on testimony as a source of knowledge is necessary to the development of a more large and comprehensive scientific understanding by science students. 相似文献

Responsible Research and Innovation (RRI) is a contemporary approach to promote science with and for society for aligning scientific innovations with societal needs. Literature about education for RRI is limited because it is not a widespread practice at the moment. To explore this gap, this study examines teachers’ views about a novel inquiry game with Augmented Reality to foster inquiry skills for RRI. This game about Genetic-Modified food was used by 18 educators from Secondary and Higher Education who engaged 390 students to form opinions about risks and benefits of GM cereal. The thematic analysis of qualitative data: semi-structured questionnaires, teaching reports and focus groups, revealed motivations and practices that influence teachers’ adoption of OER created with new technologies. Findings revealed that the 3-phase-model approach used in the game engaged students to “CARE” about global issues, “KNOW” science concepts and “DO” actions through an active open schooling network. The key drivers for educators’ adoption of AR inquiry games are to make learning more meaningful and engaging through students-centred approaches and topical resources for them to develop scientific knowledge and skills. However, the key requirements for that are easy-to-use technologies and pedagogical strategies for identifying learner’s achievements and difficulties. 相似文献

When evaluating equity, researchers often look at the “achievement gap.” Privileging knowledge and skills as primary outcomes of science education misses other, more subtle, but critical, outcomes indexing inequitable science education. In this comparative ethnography, we examined what it meant to “be scientific” in two fourth‐grade classes taught by teachers similarly committed to reform‐based science (RBS) practices in the service of equity. In both classrooms, students developed similar levels of scientific understanding and expressed positive attitudes about learning science. However, in one classroom, a group of African American and Latina girls expressed outright disaffiliation with promoted meanings of “smart science person” (“They are the science people. We aren't like them”), despite the fact that most of them knew the science equally well or, in one case, better than, their classmates. To make sense of these findings, we examine the normative practice of “sharing scientific ideas” in each classroom, a comparison that provided a robust account of the differently accessible meanings of scientific knowledge, scientific investigation, and scientific person in each setting. The findings illustrate that research with equity aims demands attention to culture (everyday classroom practices that promote particular meanings of “science”) and normative identities (culturally produced meanings of “science person” and the accessibility of those meanings). The study: (1) encourages researchers to question taken‐for‐granted assumptions and complexities of RBS and (2) demonstrates to practitioners that enacting what might look like RBS and producing students who know and can do science are but pieces of what it takes to achieve equitable science education. © 2011 Wiley Periodicals, Inc., Inc.

Working at scientists’ elbows is one suggestion that educators make to improve science education, because such “authentic experiences” provide students with various types of science knowledge. However, there is an ongoing debate in the literature about the assumption that authentic science activities can enhance students’ understandings of scientific practice. The purpose of the study is to further address the debate in terms of the ethnographic data collected during an internship programme for high school students right through to their public presentations at the end. Drawing on activity theory to analyse these presentations, we found that students presented scientific practice as accomplished by individual personnel without collaboration in the laboratory. However, our ethnographic data of their internship interaction show that students have had conversations about the complex collaborations within and outside the laboratory. This phenomenon leads us to claim that students experienced authentic science in their internships, but their subsequent representations of authentic science are incomplete. That is, participating in authentic science internships and reporting scientific practice are embedded activities that constitute different goals and conditions rather than unrefracted reflections of one another. The debate on the influence on students’ understanding of science practice is not simply related to situating students in authentic science contexts, but also related to students’ values and ideology of reporting their understanding of and about science. To help students see these “invisible” moments of science practice is therefore crucial. We make suggestions for how the invisible in and of authentic science may be made visible. 相似文献

Why would individuals who are capable of learning opt not to? Learning is important for stability and success. It would seem rational that students in groups that are frequently underrepresented or marginalized would be motivated to learn. However, negotiation of multiple identities and self-beliefs can impact motivations to learn. For example, young African American males frequently adopt a “cool pose” in their approach to education. They maintain that they do not care and will not try to be a part of the existing educational system. To better understand these issues, we studied African American males in the Glitch Game Testers program. High school students in the Glitch program worked as paid game testers and took workshops in computer science. More than 65% of the participants went on to study computing after high school. We found that these students persisted with education and computing because they navigated around motivations to not learn by creating many different faces for their involvement with Glitch. In this article, we explore the use and design implications of face-saving tactics these young men used to “geek out” on computer programming, choose computer science for their career, and maintain their current identities with friends and families. 相似文献

Nuclear science has uses and applications that are relevant and crucial for world peace and sustainable development, so knowledge of its basic concepts and topics should constitute an integral part of civic scientific literacy. We have used two newspaper articles that deal with uses of nuclear science that are directly relevant to life, society, economy, and international politics. One article discusses a new thermonuclear reactor, and the second one is about depleted uranium and its danger for health. 189 first-year undergraduate physics and primary education Greek students were given one of the two articles each, and asked to answer a number of accompanying questions dealing with knowledge that is part of the Greek high school curriculum. The study was repeated with 272 first-year undergraduate physics, physics education, science education, and primary education Turkish students. Acceptable or partially acceptable answers were provided on average by around 20 % of Greek and 11 % of Turkish students, while a large proportion (on the average, around 50 % of Greek and 27 % of Turkish students) abstained from answering the questions. These findings are disappointing, but should be seen in the light of the limited or no coverage of the relevant learning material in the Greek and the Turkish high-school programs. Student conceptual difficulties, misconceptions and implications for research and high school curricula are discussed. 相似文献

This study conducts a textbook analysis in the frame of the following working hypothesis: The transformation of scientific knowledge into school knowledge is expected to reproduce the problems encountered with the scientific knowledge itself or generate additional problems, which may both induce misconceptions in textbook users. Specifically, we describe four epistemological problems associated with how the concept of “ecosystem” is elaborated within ecological science and we examine how each problem is reproduced in the biology textbook utilized by Greek students in the 12th grade and the resulting teacher and student misunderstandings that may occur. Our research demonstrates that the authors of the textbook address these problems by appealing simultaneously to holistic and reductionist ideas. This results in a meaningless and confused depiction of “ecosystem” and may provoke many serious misconceptions on the part of textbook users, for example, that an ecosystem is a system that can be applied to every set of interrelated ecological objects irrespective of the organizational level to which these entities belong or how these entities are related to each other. The implications of these phenomena for science education research are discussed from a perspective that stresses the role of background assumptions in the understanding of declarative knowledge. 相似文献

This study examined the Swedish national tests in chemistry for implicit and explicit values. The chemistry subject is understudied compared to biology and physics and students view chemistry as their least interesting science subject. The Swedish national science assessments aim to support equitable and fair evaluation of students, to concretize the goals in the chemistry syllabus and to increase student achievement. Discourse and multimodal analyses, based on feminist and critical didactic theories, were used to examine the test’s norms and values. The results revealed that the chemistry discourse presented in the tests showed a traditional view of science from the topics discussed (for example, oil and metal), in the way women, men and youth are portrayed, and how their science interests are highlighted or neglected. An elitist view of science emerges from the test, with distinct gender and age biases. Students could interpret these biases as a message that only “the right type” of person may come into the chemistry epistemological community, that is, into this special sociocultural group that harbours a common view about this knowledge. This perspective may have an impact on students’ achievement and thereby prevent support for an equitable and fair evaluation. Understanding the underlying evaluative meanings that come with science teaching is a question of democracy since it may affect students’ feelings of inclusion or exclusion. The norms and values harboured in the tests will also affect teaching since the teachers are given examples of how the goals in the syllabus can be concretized. 相似文献

This essay discusses Anna Danielsson’s article “In the physics class: university physics students’ enactments of class and gender in the context of laboratory work”. The situated co-construction of knowledge and identity forms the crucial vantage point and I argue that it is a point of intersection between the history of science and research in science education. The former can provide a valuable understanding of the historicity of learning science. I thus highlight the importance of knowledge as situated in time and space, for instance the importance of the historical division between “head and hand” clearly visible in the discourse of Danielsson’s informants. Moreover, the article discusses how identity is produced in specific knowledge contexts through repeated performances. The article closes by briefly suggesting analytical alternatives, in particular “belonging” and “imitation”. Both draw on post-structuralist ideas about the citational nature of identity. Belonging is created by citing and reinstating norms. Imitating knowledge, identity and norms is an issue that should be brought to the fore when we speak of education and training. 相似文献

Conversational functions for knowledge building communities: a coding scheme for online interactions
Stefano Cacciamani Vittore Perrucci Ahmad Khanlari 《Educational technology research and development : ETR & D》2018,66(6):1529-1546
The aim of this study was to develop a coding scheme rooted in the Knowledge Building model, named Conversational Functions for Knowledge Building (CF4KB), to analyze students’ interactions in an online undergraduate course. In order to develop the coding scheme, we analyzed students discourse and identified the kinds of “Conversational Functions” students performed. Connecting these identified functions with Knowledge Building Model principles, we developed the coding scheme to analyze knowledge building [In the present article, we used “Knowledge Building” to indicate the theoretical model and “knowledge building” to refer to the activity of the community members.] activity. Applying the resulting coding scheme, two independent judges coded 186 messages posted into Knowledge Forum by 26 students (5 men and 21 women) attending the online course of Educational Psychology at University of Valle d’Aosta to develop the coding scheme. The inter-coder agreements obtained were 77.3 and 78.0%, with Cohen’s K?=?0.68 and 0.66, respectively for Specific and Global Conversational Functions level. The theoretical implications and possible uses in different contexts for future inquiry of this instrument are discussed. 相似文献

The nature of knowledge in vocational education is often described in dichotomies such as theory versus practice or general versus specific. Although different scholars now acknowledge that vocational knowledge is more than putting bits of theoretical and practical knowledge together, it is still unclear how vocational knowledge should be theorised instead. In this article we theorise the idea of contextualising vocational knowledge to understand the nature of vocational knowledge and illustrate this process of contextualising with empirical examples from culinary education. We adopt an activity-theoretical focus on contextualising that involves both particularising and providing coherence. We posit a cognitive process of meaning making where meaning derives from seeing the relationships of parts to the whole. The aspects of the nature of coherence and the relation between concepts and actions seem rather underdeveloped in vocational education theory. To characterise this process at a micro-level, we enhance the activity-theory approach with an inferentialist one. Inferentialism offers a way to focus on reasons and inferential relations between concepts and actions that provides coherence in vocational knowledge. To characterise the broad spectrum of processes relevant for vocational knowledge, we propose the terms “conceptualising” and “concretising”. Conceptualising involves inferring what follows from understanding a concept in a particular situation in relation to the meaning of other concepts. Concretising involves inferring what follows from understanding an aspect of the occupational practice in which students are participating. We argue that this way of framing vocational knowledge helps to better understand its nature and development. 相似文献

Teacher education is in the grip of change. Due to the new Australian Curriculum, no longer is it possible to plan and implement lessons without considering the inclusion of Information and Communication Technologies. Simply knowing about the latest technology gadgets is not enough. Information literacy is essential in today’s information-rich learning and working environment. Students and teachers must be able to engage with diverse learning technologies efficiently and effectively in the search for the “right information” at the “right time” for the “right purpose”. Key information literacy and inquiry skills have been recognised as vital learning goals by the Australian Curriculum Assessment and Reporting Authority and the International Society for Technology in Education and are thus critical in science teacher education. This paper examines the overlap of technology, pedagogy and science content in the Technological Pedagogical and Content Knowledge (TPACK) framework and its affordances for science educators, at the intersection between technology knowledge, science pedagogy (information literacy and inquiry) and science content knowledge. Following an introduction of the TPACK framework for science education, the paper reports the research findings, which illustrate that 90% of pre-service teachers thought the experimental unit improved their understanding of the inquiry process, 88% reported more confidence in their understanding of science concepts and 94% of students reported an increase in their knowledge and confidence of Web 2.0 tools in supporting scientific inquiry in science. The implications of this study are that the online inquiry improved students’ knowledge and confidence in the skills and processes associated with inquiry and in science concepts. 相似文献
