Energy is an abstract science concept, so the ways that we think and talk about energy rely heavily on ontological metaphors: metaphors for what kind of thing energy is. Two commonly used ontological metaphors for energy are energy as a substance and energy as a vertical location. Our previous work has demonstrated that students and experts can productively use both the substance and location ontologies for energy. In this paper, we use Fauconnier and Turner's conceptual blending framework to demonstrate that experts and novices can successfully blend the substance and location ontologies into a coherent mental model in order to reason about energy. Our data come from classroom recordings of a physics professor teaching a physics course for the life sciences, and from an interview with an undergraduate student in that course. We analyze these data using predicate analysis and gesture analysis, looking at verbal utterances, gestures, and the interaction between them. This analysis yields evidence that the speakers are blending the substance and location ontologies into a single blended mental space.  相似文献

The meaning of the term energy varies widely in scientific and colloquial discourse. Teasing apart the different connotations of the term can be especially challenging for non-science majors. In this study, undergraduate students taking an interdisciplinary, general science course (n?=?49) were asked to explain the role of energy in five contexts: radiation, transportation, generating electricity, earthquakes, and the big bang theory. The responses were qualitatively analyzed under the framework of conceptual metaphor theory. This study presents evidence that non-science major students spontaneously use metaphorical language that is consistent with the conceptual metaphors of energy previously identified in the discourse of students in introductory physics, biology, and chemistry courses. Furthermore, most students used multiple coherent metaphors to explain the role of energy in these complex topics. This demonstrates that these conceptual metaphors for energy have broader applicability than just traditional scientific contexts. Implications for this work as a formative assessment tool in instruction will also be discussed.  相似文献

In this paper, we report an analysis of metaphors used by three science teachers in their classroom discourse and consider the implications of this research for the image of science that students are likely to construct. Teacher beliefs about the nature of science are implicit and entrenched and may be contrary to both contemporary philosophies of science and constructivist theory. We argue that the presence of metaphors such ateaching as a journey, knowledge as object andteacher as pathfinder in teachers' classroom discourse signify the implicit existence of a powerful objectivist epistemology that governs teachers' pedagogies. If students are to construct contemporary views of the nature of science and if constuctivist pedagogy is to develop in the science classroom then science teachers need to reflect on their use of these role-determining objectivist metaphors.  相似文献

This article examines the role elementary school children’s spontaneous metaphors play in learning science. The data consists of tape recordings of about 25 h from five different schools. The material is analysed using a practical epistemology analysis and by using Dewey’s ideas on the continuity and transformation of experience. The results show the rich and varied meanings that children put into their spontaneous metaphors. Their metaphors deal with facts as well as norms and aesthetics in relation to the science content taught and they influence learning both through what is made salient, as well as through their relations to the children’s possibilities of proceeding with their undertakings. Often one and the same metaphor encompassed all these cognitive, aesthetic and normative aspects at the same time. It is discussed how this rich meaning can be cultured in a productive way, and how the children’s spontaneous metaphors, with all their relations, can be used to enhance conceptual learning and also learning about the nature of metaphor use in science. Through their connection with various experiences of the children, it is also shown how children’s spontaneous metaphors have the potential to enliven and humanise the subject.  相似文献

Building on the idea that "discourse does ideological work" (Wodak, 1996), this article examines how school leaders use metaphors that convey as well as construct concepts of diversity, intergroup relations, and equity. The author draws on data from interviews with school leaders in the United States who were focusing on improving race relations in their schools. An analysis of metaphors in these interviews reveals differing ideologies of equity and intergroup relations. Based on this analysis, the author suggests that professional development programs for school leaders ought to include a critical approach to language to enhance leaders' awareness of the way discourse creates and reinforces ideologies, and to enable them to use language strategically to support equity-based reforms.  相似文献

In this article, we utilize the concepts of conceptual metaphors, cultural models, and master myths to discuss the ways by which three new immigrant children, native speakers of Spanish, were developing conceptions of English language, literacy, and learner's identities. Our findings point to 3 main metaphors that were often implicit in the school environment: (a) writing as procedures, (b) English as success, and (c) learners as test scoring categories. These metaphorical conceptualizations appear to be a reflection of the discourse around No Child Left Behind (NCLB) policies that permeate American school contexts. We argue that this discourse can serve to promote reduced conceptions of literacy (and writing in particular), to essentialize learners' identities, and to preserve the hegemony of English. We suggest that a focus on meaning during literacy instruction can be helpful in providing opportunities to counteract these conceptions and to foster the development of more robust ones.  相似文献

We demonstrate that a particular blended learning space is especially productive in developing understanding of energy transfers and transformations. In this blended space, naturally occurring learner interactions like body movement, gesture, and metaphorical speech are blended with a conceptual metaphor of energy as a substance in a class of activities called Energy Theater. We illustrate several mechanisms by which the blended aspect of the learning environment promotes productive intellectual engagement with key conceptual issues in the learning of energy, including distinguishing among energy processes, disambiguating matter and energy, identifying energy transfer, and representing energy as a conserved quantity. Conceptual advancement appears to be promoted especially by the symbolic material and social structure of the Energy Theater environment, in which energy is represented by participants and objects are represented by areas demarcated by loops of rope, and by Energy Theater's embodied action, including body locomotion, gesture, and coordination of speech with symbolic spaces in the Energy Theater arena. Our conclusions are (1) that specific conceptual metaphors can be leveraged to benefit science instruction via the blending of an abstract space of ideas with multiple modes of concrete human action, and (2) that participants’ structured improvisation plays an important role in leveraging the blend for their intellectual development.  相似文献

Scientists’ science differs remarkably from school science. In order to be taught to students, science is recontextualized from scientific research communities to science classrooms. This paper examines scientific discourse in scientific research communities, and discusses its transformation from an internally-persuasive and authoritative discourse to a purely authoritative discourse under recontextualization. It presents the challenges that recontextualization of science poses for achievement of science literacy goals, and discusses remedial steps that science education community can take to meet them.  相似文献

ABSTRACT

It has been suggested that metaphors have a crucial influence on the way we perceive and construct the world. As a result, metaphor analysis has been used as a way to reveal, analyse and understand conceptions of teaching in higher education. This paper introduces a different way to analyse metaphors for teaching than the ones previously used in higher education. By focusing on temporarily stable, spontaneously uttered metaphors in conversation data, the unfiltered metaphors for teaching are analysed. Through a thorough analysis of eight interviews with lecturers from business management, it is established how teaching in this context is conceptualised as a vehicle on tracks and as having levels as well as depth and width. It is discussed how the identified metaphors open up a space of possibilities for the lecturers and to what extent these results can be generalised beyond this context.  相似文献

This paper discusses the metaphors and discourses employed in the current Skills for Life Strategy in terms of the identity of potential adult literacy learners. It argues that metaphors and discourses are necessarily value laden and reflect the beliefs of those with authority to influence others. The current Strategy, it is argued, is based on a discourse of deficit, outcomes and employability that positions adult literacy learners as ‘depersonalised others’.  相似文献

Scientific facts are loaded with values, but, it is argued, this does not viciously compromise the objectivity of scientific claims, because the values that permeate scientific discourse (a) are loaded in turn with facts, (b) are not immune from critical revision, and (c) have changed in the past and continue to be subjected to revision. In science, unlike such enterprises as Scientific Creationism, values are discovered, introduced, tested and challenged in the same way that other aspects of scientific discourse are. All of this makes scientific discourse relevant to the contemporary exploration and critique of human values in general, particularly as more aspects of life become illuminated by science.Research for this paper was made possible in part by RF-CUNY (grant PSC-CUNY 669106). A preliminary version of this paper was given at Universite de Fribourg, Switzerland, May 1990.  相似文献

Classroom discourse can affect various aspects of student learning in science. The present study examines interactions between classroom discourse, specifically teacher questioning, and related student cognitive engagement in middle school science. Observations were conducted throughout the school year in 10 middle school science classrooms using the Electronic Quality of Inquiry Protocol, which is designed, among other things, to measure observable aspects of student cognitive engagement and discourse factors during science instruction. Results from these observations indicate positive correlations between students’ cognitive engagement and the following aspects of classroom discourse: questioning level, complexity of questions, questioning ecology, communication patterns, and classroom interactions. A sequential explanatory mixed-methods design provides a detailed look at each aspect of classroom discourse which showed a positive effect on student cognitive level during science instruction. Implications for classroom practice, teacher education, and professional development are discussed.  相似文献

This study examines metaphors about learning produced by a group of eighteen students at a big public university in Malaysia. The learner perspective is placed within a wider discourse on education in order to explore whether the images employed by the learners to describe their learning reflect the dominant conception of education as “production”. The metaphors supplied by the participants were analyzed and classified into several themes. None of the metaphors generated by the students alluded to the images that link education with “production”. The study contends that the student perspective on education can enrich educational discourse and highlight the previously obscured notions on education and learning.  相似文献

In this study discourse and conversation analyses were performed on talk by science and mathematics teaching faculty participating in reforming content courses for teacher candidates participating in a mathematics and science teacher preparation project (upper elementary and middle level). The context of the study was the Maryland Collaborative for Teacher Preparation (MCTP), a National Science Foundation funded project in the USA. The study's goal was to explore the use of discourse and conversation analyses as ways to understand faculty beliefs concerning mathematics and science, two disciplines the MCTP project aimed to connect. Discussion focused on two areas: (1) the comparison of the discourse on science and mathematics by the science, mathematics, and pedagogy content specialists, and (2) the impact of collaboration on the science and mathematics teaching faculty's conversation on science and mathematics. An implication of this study is to promote the analysis of talk as way to inform and direct faculty transformation in science and mathematics teacher education programs. Future research is recommended.  相似文献

Research suggests that understanding new images of mathematics is very challenging and can contribute to teacher resistance. An explicit exploration of personal views of mathematics may be necessary for pedagogical change. One possible way for exploring these images is through mathematical metaphors. As metaphors focus on similarities, they can be used to express already-held perceptions about the nature of mathematics. In addition to providing a way of talking about current views of mathematics, the analogous dimensions of metaphors can prompt new ways of thinking about these images. In this article, I consider the use of metaphors as a strategy for explicating elementary teachers’ views of mathematics. I claim that the investigation of metaphors of mathematics helped create a shared communicative space and enhanced the quality of the discussion with the teachers. In particular, our exploration of the metaphor mathematics is a language encouraged a consideration of the humanistic dimensions of mathematics and contributed to a varied re-imaging of mathematics.  相似文献

ABSTRACT:  The paper explores the current rationale for primary science in England with a focus on how competing perspectives arising from perceptions of educational ideology and policy discourse have helped to shape current practice. The aim will be to provide a conceptual understanding of this by focusing specifically on how policy has influenced practice. In particular it will consider the way in which discourse and policy text have contributed to the emergent rationale for primary science which in many ways reflects conflicting influences, views and policies. Data were collected over a year from a regional survey and from four case-study primary schools. The findings suggest that teachers in primary schools face tensions between promoting both an educational and a political rationale for learning primary science. The paper will conclude by suggesting that the justification for primary science should be based on what we already know about how children learn science as well as helping them to develop an understanding of science and how it influences and is intrinsically linked to the needs of society.  相似文献

In recent studies of learning theories, a new methodology that integrates two prevailing metaphors of learning (acquisition and participation) has been discussed. However, current analytical techniques are insufficient for analyzing how social knowledge develops through learners' discourse and how individual learners contribute to this development. In this paper, we propose a novel approach to analyzing learning from an integrative perspective and present a social network analysis application that uses learner discourse as input data: Knowledge Building Discourse Explorer (KBDeX). To investigate the utility of this approach, discourse data analyzed in a previous study is re-examined through social network analysis supported by KBDeX. Results suggest that social network analysis can qualitatively and quantitatively support the conclusions from the previous study. In addition, social network analysis can reveal potential points that are pivotal for social knowledge advancement in groups, and can identify each individual's contribution to this advancement. On the basis of these results, we discuss how social network analysis could be integrated into existing in-depth discourse analysis.  相似文献

ABSTRACT

This paper analyses the psychometric paradigm for understanding educational measurement and standard setting by considering the extent to which that understanding is based on metaphors. I argue that through the metaphors ‘more is up’ and ‘good is up’ we spatialise concepts that are not intrinsically spatial. Human abilities form a distinct conceptual category, with complex and varying rules for the correct usage of different ability terms. The fact that most abilities can be discussed in terms of both ‘possession’ and of ‘more or less’ invites reification, spatialisation, and hence the application of measurement metaphors. Insights into the measurement of abilities can be gained by careful consideration of how ability terms are used in normal discourse, especially of athletic abilities which are partly quantified in terms of attributes that are physically measureable. The fuzziness of natural language creates some of the problems in understanding standards in both psychometrics and physical measurement.  相似文献
